 18/01/16

Set up as last week but with 8us shaping time.

With detector connected, still seeing rail-to-rail noise on waveforms in nnaida13 and double peaking in all nnaida.

Measured various resistances around the system to gauge quality of grounding connections (all measured in Ohms).

     - NIM crate to PCB LEMO connector:                                        4.8

     - NIM crate to mezzanine Cu block:                                           5.3    -> Plastic guide pins now installed.

     - Between LEMO connectors on the adapter boards:           0.19

     - nnaida11/12 drain wire to nnaida13/14 drain wire:            0.25

     - RH coupler nnaida13 to RH coupler nnaida11:                  1.4

     - LEMO to ribbon shielding nnaida13:                                     0.2

     - LEMO to RH coupler shielding nnaida13:                            0.4

Double peaking not seen in RIKEN or by PCS during his tests -> most likely pickup of external noise.

Connected multiple different cable types to see effect they have on the sinusoidal wave seen in the waveforms and on the double peaking.

       - nnaida11: LH coupler (not shielded) + 45cm ribbon (shielded) + RH coupler (shielded)

       - nnaida12: LH coupler (not shielded) + 45cm ribbon (shielded)

       - nnaida13: old style 90cm kapton (19/02/14 revision)

       - nnaida14: 45cm thin kapton (shielded) with foil over loose end

Setting as last week, with 2us shaping time.

Peak -to-peak differences in all nnaida for several channels:

               |   nnaida11    |                       nnaida12                    |   nnaida13   |   nnaida14    

    1.4.L  |       157          |                           123                           |         160        |   single peak of width ~400ch

Explains v. large peak width. (Attachments 3-5)

19/01/16

Swapped cables on nnaida11 and nnaida13. Now have:

       - nnaida11: old style 90cm kapton (19/02/14 revision)

       - nnaida12: LH coupler (not shielded) + 45cm ribbon (shielded)

       - nnaida13: LH coupler (not shielded) + 45cm ribbon (shielded) + RH coupler (shielded)

       - nnaida14: 45cm thin kapton (shielded) with foil over loose end

In nnaida13 see ripple on baseline of waveform with period ~30ch = 600ns (@20ns per ch) => frequency of 1.67 MHz.  (Attachment 6+7)
 

Resistance between drain wire end and ribbon shielding on nnaida13 cabele:   ~0.8 Ohms.

        "                                                          "     RH coupler shielding on nnaida13:    ~1.1 Ohms.

For shielded ribbon cable on nnaida13, see fairly flat waveforms. High frequency transients pass through, but no sign of sinusoidal wave over time window of 6us.   (Attachment 9)

After swapping cables on nnaida11 and nnaida13 (only change to system), now see single, Gaussian peaks in nnaida12 with widths ~40ch.

For nnaida12:

           Shaping time (us)     |     Avg peak width (ch)        (avg of 1.8/9/10/11.L peak widths)

                      0.5                     |                   35

                      1.0                     |                   39      (1.11 width ~50ch, all others ~37-42)

                      2.0                     |                   39      (   "                                                      "     )

                      4.0                     |                   35      (1.11 width ~45ch, all others ~32-38)

                      8.0                     |                   37

At 8us shaping time: in nnaida11 (old style cable), see single pulser peak of width ~150 ch.

                                           nnaida13, still see double peaking with peak separation of ~90ch and an extra structure, like a small shoulder, on the outside of the peaks.    (Attachments 8+10)

                                           nnaida14, not fully double peaked, more a peak with a shoulder ~40ch apart.

At 2us shaping time: in nnaida11, pusler peak width back to ~300ch.

                                           nnaida13, retains extra structure on outside of peaks, but peak searation increased to ~150ch.

                                           nnaida14, double peaked, with peak separation of ~65ch.

(Attachments 11-15)

Cannot see waveforms on nnaida12, so swapped cables with nnaida11. Also acts as test of whether the good performance seen in nnaida12 follows the cables or is something to do with the FEE.

Now have:

       - nnaida11: LH coupler (not shielded) + 45cm ribbon (shielded)

       - nnaida12:  old style 90cm kapton (19/02/14 revision)

Now see some Gaussian peaks in nnaida11 with width of ~60ch @2us shaping time, however some peaks seem to have a slight shoulder.

      > suggests issue causing double-peaking is still present (and likely was in nnaida12), but is more/less apparent in some channels than others.

Questions:

     ** Is this just a very well shielded cable, or something to do with the intrinsic properties of this specific cable?

     ** What happens if a RH coupler is added?

     ** What happens if the RH coupler is removed from the cable connected to nnaida13?

Added RH coupler to cable on nnaida11.

Measured some resistances of the shielding on the nnaida11 (good performance - single peaks) cable and the nnaida13 (double peaks) cable:

       - drain wire to far end of shielding:      nnaida11 = 0.2 Ohms           nnaida13 = 0.2 Ohms

       - drain wire to RH coupler:                    nnaida11 = 0.4 Ohms            nnaida13 = 0.5 Ohms

       - far end of nnaida11 cable shielding to far end of nnaida13 cable shielding:     0.05 Ohms   (this seems wrong considering pushing the multimeter probes together gets 0.14 Ohms, but was repeated several times and was always 0.05 Ohms)

With addition of RH coupler to nnaida11 (and shaping time still at 2us):       (Attachments 16+17)

     - nnaida11 peaks show slight shoulder and increased width of ~110ch.

     - nnaida12 now sees noise over full-scale range

     - nnaida13 now quad peaked.

     - nnaida14 still double peaked, but peak separation increased to ~150ch.

Removed RH coupler from nnaida11, all peaks go back to how they were previously, before its addition (Something is repeatable - excellent!)

     - some peaks in nnaida11 now non-Gaussian nad with widths ~130ch. Most Gaussian and width ~50ch.

Removed RH coupler from nnaida13:

    - no real change in the spectra of any nnaida    -> what is the difference between the cables on nnaida11/13???

Stock take of ribbon cables currently at DL:

     - 90cm                   = 16

     - 45cm                   = 16   (4 with me for testing in Edinburgh this week. Will be returned to DL next week)

     - LH couplers       = 10   (2 with me for testing in Edinburgh this week. Will be returned to DL next week)

     - RH couplers       = 10  (2 with me for testing in Edinburgh this week. Will be returned to DL next week) 

 25/01/16

On start up, received error when trying to access spectrum browser (attachment 1)   => required restart of 'Http for AIDA'

At 2us shaping time, and all other setting as last week, the situation remains the same

    - nnaida11 has width ~50ch, nnaida12 has width ~300ch, nnaida13 is quad peaked and nnaida14 is not quite Gaussian but has width of ~80ch (possibly two peaks very close together)

Change shaping time to 8us.

Swap cables to see if the cable is the source. Currently have two LH coupler + shielded ribbon cables connected to nnaida11/13 (11 good performance, 13 quad peaked)

     - swapped the ribbon cables over but left the couplers where they were to see if the good performance is a consequence of something intrinsic to a particular ribbon or coupler.

     - nnaida11 now has width ~40ch                  (attachment 2)

     - nnaida13 now back to double peaked       (attachment 3)

     - inconclusive.

Could old style kapton laid next to nnaida11 be shielding it due to the built in screen? (the kapton is laid against the ribbon cable)

     - removing the kapton makes no difference to widths, other than nnaida12 which comes down to ~15ch (as expected)

Clipping cable ends together makes no difference, and no combination of jumpers could improve the widths.

Bending cables through 90 degrees makes no difference either (if they were acting as aerials).

Swapped complete PCBs with cables still in place over. Test first thing tomorrow.

26/01/16

Swapping PCBs produced no difference

     - nnaida11 has widths of ~50-60ch, although some structure visible in some peaks

     - nnaida14 sees double peaks.

Clipping ribbon ends together now makes things worse.

Swapped PSU cables to nnaida11/14

     - nnaida11 now marginally worse @ ~70ch width

     - nnaida14 sees no obvious change

Connected PSU chasis to NIM crate - no change.

Added two more ribbon + HL/RH couplers to system. Now:

      - nnaida11 = LH + ribbon

      - nnaida12 = LH + ribbon + RH

      - nnaida13 = LH + ribbon + RH

      - nnaida14 = LH + ribon

Clipped drain wire to LEMO connectors on PCB instead of pulser BNC cable.

See marked improvement in performance. All nnaida now have single Gaussian peaks with widths now:   (attachments 4-6)

       - nnaiada11 at ~35ch

       - nnaida12 at ~70ch

       - nnaida13 at ~80-120ch

       - nnaida14 at ~45-55ch (3 at ~80-150ch)

Added RH coupler to nnaida11/14, with thin braid taped over joint in shielding to reduced resistance

       - nnaida11 widths increase slightly to ~40-60ch

       - nnaida14 widths increase slightly to ~60-80ch, few round ~100-120

This is consistent with the RH coupler increasing widths by ~25ch, as seen in previous tests.

See occasional ripple through waveforms in nnaida11/14    (attachments 7-11).

      - expanded view shows period of 34 samples  ==> 680ns   ==> frequency ~1.5MHz

Variation with shaping time (avg peak width over a several channels):

* = some non-Gaussian peaks

Connected detector, biased to +200V (+ve core to nnaida12, -ve braid to nnaida14) with leakage current = 9uA.

At 8us shaping time, and with Lk1 fitted on nnaida13/14 RevC adapter, peaks across all nnaida have widths ~70ch and are all single Gaussian peaks.   (attachments 12-15)

Currently running with a source, and everything seems to be running fine in terms of histograms doing what we expect, no error messages etc.

Tried to start the merger and tape server, but the merger reports as waiting for the first SYNC.

Checked the stats page and sure enough, no SYCs are being produced.

Performed a re-sync from the MasterTS page but nothing changed.

Started up system. Biased det to +200V 

08/02/16

Spoke to PJC-S -> Ethernet cables from FEEs to switch are all 4m Cat6.

System powered on with bias to detector of +200V and leakage current of 6.4uA at room temp 19.0oC.

Double peaking present again in nnaida11/12 -> individual peaks @ ~100ch FWHM with separation ~150ch @ 2us shaping time.

Double peaking also present in nnaida13/14 -> indiv peaks ~100ch FWHM and separation ~90ch.

Changing grounding had no effect.

Made ribbon cable with 2 separately shielded halves plus connecting Cu tape strip at FEE and + drain wire in contact with both halves - single peaks - widths of ~110-160ch.

09/02/16

Added conductive gasket to Cu mount blocks

      - resistance between Cu and gasket ~0.2 Ohms (probe-to-probe = 0.16 Ohms)

      - LEMO connector to Cu mount block ~0.35 Ohms

      - LEMO to LEMO (between adapter PCBs) ~0.55 Ohms (connected by heavy duty Cu braid)

Powered system on. Bias of +200V and leakage current = 5.5uA @ room temp 19.5oC.

With gasket added and heavy duty Cu braid between mount blocks, pulser FWHM in nnaida11 ~ 62ch and in nnaida13 ~72ch at shaping time of 8us.

I have been trying to compile the sort program I have been working on in Edinburgh so I can work on it locally
while at RIKEN.

When compiling i receive the error shown in make.log (attached) saying that there are undefined reference in
DataSource.cpp.
Also attached is the make output when compiled in Edinburgh - basically just 'unused variable' warnings.

This is exactly the same DataSource.cpp I am using in Edinburgh. I have carried out 'diff' on the DataSpyLib and
DataXferLib directories which are included
in the Makefile and no differences are present. I have also done this for DataSource directory and again, there
are no differences between what I am running here and in Edinburgh.

The only difference I have been able to observe so far is that in Edinburgh I am using g++ version:

      Unable to regain control of system. Power cycle FEEs while DK+NB install more shielding.

2:55 Made attempts to solve the noise issue that was plaguing DSSD1.
     Attempts at checking the cabling, making sure the detectors were light sealed and switching the bias cables
         around were unsuccessful.
     A blue cable was found to be laying across the snout of AIDA that runs as a temperature probe for one of the
         clover detectors.
     Moving this cable appears to have solved this issue (Has been locked in position). See pulser spectrum in

7:09 PPACs are discharging very frequently.

7:39 counted 8 discharges.  It's about once in four minutes.  An acceptable discharge rate is several times in
one shift.
     Firstly, each discharge damages the PPAC.  Even 10 to 20 discharges can easily cause dead regions of cm size.
     Secondly, with the frequency of discharge, we are now missing like as much as 25% of all events (at least
at a given PPAC)
     As the detector becomes more damaged, it can discharge more frequently.
     Moving the detector's position slightly can help to alleviate the problem by putting the beam on a fresh region
     Anyway, as for a parasitic run they can do whatever they want, but it seems they are mis-operating the PPACs
     Basically the voltage is too high or the detector is too old and needs to be replaced.

10.00 Powered system on and biased.
      Bias voltages and leakage currents ok (see att. 1). Ambient temp @23.1oC.
      
14.00 Shunji wanted to do some checks with the LN2 fill.
      Seems to perhaps be a problem with unshielded cables to the valve switches.
      With control box, outlet valve and cables to all valves behind LN2 tank, AIDA survives LN2 fill.
      Parts ordered to facilitate moving of components behind the LN2 tank, away from AIDA.
      Will carry out further tests once these have been fitted.

17.00 FWHM seem reasonable and similar to Dec 2016.
      n-side FEEs see average pulser FWHM of ~70-80ch. nnaida19 noticeably worse @ ~150ch. (att. 2+3)
      p-side FEEs worse with average pulser FWHM of ~200ch. nnaida13 worst of these, showing non-Gaussian peaks
with widths @ ~300ch. (att. 4+5)
      Will not attempt to solve this now as they must all be disconnected to sort problem with nnaida1.

10.00 Investigating DSSD2 (MSL BB18-1000 3058-9) missing channels, found broken bond wires on rear side (~1/4).
      Replaced with 3058-3.
      Stack order now:
            |   3058-4
      beam  |   3058-3
            |   2998-23
            |   3058-5
            |   3058-6
            V   3058-7

12.00 All detectors, including the new replacement bias correctly (see att. 1).

14.00 Shunji has mentioned moving AIDA+BRIKEN forward by ~1m due to concerns about focusing the accurately at such a rearward position.
      The afternoon was spent removing the EURICA rails to enable the push forward of AIDA+BRIKEN.

18.00 The DAQ was set running with the new detector included. All system checks passed apart from nnaida19 ADC calibration.
      Pulser peak widths are mostly ~70-90ch for all FEEs. This is similar to Tuesday for the n-side FEEs (att. 2-4) and an improvement for the p-side FEEs (att. 5-7).
      Having said that, some spectra show peaks with shoulders or tails and a few feature multiple discreet peaks.
      We will look at this over the next couple of days, depending on when the final move/alignment of AIDA+BRIKEN is completed.
