Spectrum s400 displays the frequency of bits 0-47 of the (MBS) 25MHz correlation scaler.

For those bits which can be expected to cycle often within the sampling period we would
expect to observe each bit with equal probability and this is observed for bits 0-31.
Conclude there is no evidence for hardware/firmware problems with the AIDA 25MHz correlation
clock for bits 0-31 and therefore probably not for bits 32-47 either.

I think the SyncCheck issues observed could due to:

1) the effect of sampling data from the AIDA TapeServer data buffers,
2) arithmetic/coding bug in the SyncCheck code
... or ?

I don't recall observing these issues before ...  does that mean we weren't looking? ... or
that there has been some change to hardware operation, software ... ?

Entry  Mon Nov 28 15:53:39 2016, AE, AT, RG, CG, DAQ synchronization  7x

We noticed a peculiar feature in the time-stamp synchronization monitor. The spectra of timestamp difference between pairs of DAQ systems show, for all possible pair combinations, a peak at Delta(ts)= 65535 = 2**15

This corresponds to a difference of 2.6 ms (for 25MHz correlation clock). See the attachments taken ~23:00 of Nov 28th.

We performed the AIDA system-wide checks (no errors) and a timestamp reset, but the second peak at 65K is still there (we also checked that there is no peak at 2*65K, at least in a short run period).

We also observed a double peak for timestam-differences close to zero, which we interpret as good correlations (attachment 2). Note, however, that this double peak became much supprese around midnight (see attachment 6 and 7).

From analysis of ion (BigRIPS) and implant (AIDA) correlations we have some confidence that these two DAQs are synchronized; see entry https://elog.ph.ed.ac.uk/AIDA/492 where we identify an implant for 20% ofions at F11 (and with an implantatin profile that, for example, is consistent with changes to the degrader configuration)

 

Entry  Mon Nov 28 13:12:31 2016, PV, AE, Liu, Implantation profile in AIDA with 8mm Al replacing 3 mm Pb 10.pngimp_dssd_106x.pngimp_pid_106x.pngimp_xy_106x.pngpid_r106x.png

Data for ~3 hrs: Nov 28th, 20:06 to 23:16

Bigrips run 1060 to 1062

AIDA run R30_ 2 to R30_40

Degrader setting: variable= (0.3mmW/1mmAl + 1mmW/1mmAl) + fixed= ( 8 mm Al)

IMPLANT PROFILE: Compare to previous setting (with 3mm Pb as fixed degrader) in elog entry https://elog.ph.ed.ac.uk/AIDA/487

In particular, attachment: https://elog.ph.ed.ac.uk/AIDA/161127_195411/run104x_imp_profile.png

The implantation positin for 40Mg seems to be well optimized (perhaps we can add ~0.5 mm Al to move it further downstream, but not more than that!).

IMPLANT EFFICIENCY: If we compare the number of Al and Mg ions in the ZDS PID for the three runs (~46000, see attachment 5) to the number of ions identified as implants (9389, see attachment 2), we get:

Implant efficiency ~ 20 %   (=9389/46000)

 

P/S: attachment: hit pattern in BRIKEN with F11 plastic (beam), only for BigRIPS run 40Mg1060

Entry  Sun Nov 27 22:35:37 2016, Liu, PV, AE, Ion hit pattern in AIDA after degrader changing aida_ion_hitpattern_run26_51to63.png

After changing degrader to optimize 40Mg, hit pattern in AIDA is shown in figure below.

The implantation position changed from right side position of  first DSSD to center position of last DSSD.

Entry  Sun Nov 27 19:33:00 2016, Liu, PV, AE, F11 degrader setting (night Nov27-Nov28) run1038_imp_profile.pngrun1038_imp_pid.pngrun104x_imp_profile.pngrun104x_imp_pid.png
Analysis of files for two more settings of F11 degrader to optimize implantation of 40Mg.

+ setting 1: from Nov 27th, 22:16
    Fixed degrader: 3 mm Pb + 1 mm Al, Variable degrader: 1.3 mm W + 2 mm Al
    AIDA run: R26_0 to R26_38
    BigRIPS run: 40Mg1037 (partial) to 40Mg1040
    see attachments: run1038_imp*png

+ setting 2: from Nov 28th, 1:38.
    Entered F11 during stripper foil change and removed 1mm Al fixed degrader (same as during Nov 26th - ~ run
40Mg1012).
    Fixed degrader: 3 mm Pb, Variable degrader: 1.3 mm W + 2 mm Al
    AIDA run: R26_39 to ...
    BigRIPS run: from 40Mg1041 to ...
    see attachments: run104x_imp*png (2 hours of data: run 1041 and 1042)

Setting 2 moved implantation depth one or two strips upstream (1.2 according to calculations). 40Mg seems to be
implanted about the third strip; a conclusion with LOW STATISTICS, but consistent with the trend of how the
implantation position depends on neutron number for the higher-count isotopes. 

Setting 2 seems to be our best option (at least without going into F11 and reconfiguring degraders). We will
continue accumulating data with it.

Attachments: the 1D plot shows the ion implant position (DSSD) gated for all ions and for Al and Mg gates in the
PID. The 2D plots show the PID with gates on implants in different DSSDs.

07.58 Bias and leakage currents ok (attachments 4+5).

09.00 Beam stopped for stripper foil change.
      1.4GB into R27_15.
      Will continue with R27.

9.13  Changed degraders and shields in F11
      Pb bricks between MUSIC 1 and MUSIC 2 were not changed, but we confirmed their positions and size of the
window.
         Width of window is 7.5 cm, height of window is larger than the MUSIC windows, depth of Pb to beam is 10 cm
      New Pb bricks placed downstream of the variable degrader
         Width of window is ~12 cm, height of window is larger than the MUSIC windows, depth of Pb to beam is 20 cm
      3 mm Pb degrader was moved from the front of the PE wall to the front of the upstream Pb shield 
         (between MUSIC 1 and 2 as described above)

9.15 BigRIPS run 1049

AIDA runs R27_15 (end portion) and all of _16, and the start of R27_17 include beam-off time.

The start of R27_18 should coincide nearly with beam on.

10.00 System-wide checks OK *except* clock status errors from amongst nnaida5, 7, 8, 15 & 16 - bit 2 always set
      and ADC calibration fail for nnaida13

10.50 BigRIPS run 1050 begins

11.02 We checked the timestamping, and it looks like BRIKEN and AIDA are not synchronized.  So we will restart runs.

11.08 R28_00 at AIDA started

11.12 All syncs look good now.

11.16 BigRIPS data file 1051

12.08 Visual scalers - see attachment 6

12.12 SyncCheck OK - see attachment 7

12.22 BigRIPS data file 1052

14.19 Sync of AIDA shows two peaks with both BRIKEN and BigRIPS, so we stop the run.
      BigRIPS should be starting a new run soon, so we will wait for them to start the new run

14.31 New AIDA run R29_0; started directly after BigRIPS 1054 (14.29 start)

16.00 Offline analysis of R27_1 and R28_14 was done with MIDAS.  See their respective eLog entries
      The main difference between these runs is R27 has the 3 mm Pb closer to AIDA than R28
      The number of implants to AIDA seems about a factor 2 higher with the 3 mm Pb closer to AIDA
      During the next chance to enter F11, we should shift the 3 mm Pb closer to AIDA again, all other things being
equal (BRIKEN impact?!)

18.22 Stop the run (R29_47) in preparation for LN2 fill.

19.30 Ambient temperature +25.7 deg C, dp.p. +0.2 deg C, RH 18.4%
      DSSSD bias & leakage currents OK - see attachments 8 & 9

19.35 Beam is stopped to exchange strippers.  Main exp. team also enters the radiation area for ~20 min
      Remove the 3mm Pb degrader (it was on the upstream side of the Pb shield between MUSIC 1 and MUSIC 2)
      Add 8 mm Al to the front of the PE wall.  This should be an equivalent dE for 40Mg we calculated.

19.59 DAQ starts (RIBF03R1/R30)

20.05 SyncCheck OK

20.06 Beam back (R30_1)
      BigRIPS data file 1060
      Degrader ( 8mm Al ) fixed + ( 0.3mm W/1mm Al + 1.0mm W/1mm Al ) variable

Entry  Sun Nov 27 12:30:41 2016, AE, PV, Energy loss in Degraders and Implantation for runs 1028 and 1033 6x

Implantation profile in AIDA

    BigRIPS file 1028 (Attachment run1028.png):  Degrader setting: 3 mm Pb(fix) + 0.8 mm W(variable) + 2 mm Al(variable)

    BigRIPS file 1033 (Attachment run1033.png):  Degrader setting: 3 mm Pb(fix) + 0.8 mm W(variable) + 2 mm Al(variable) + 1 mm Al(fix)

    BigRIPS file 1012 is in https://elog.ph.ed.ac.uk/AIDA/478 Degrader setting: 3 mm Pb(fix) + 1.3 mm W(variable) + 2 mm Al(variable)

    Observation: Some Mg isotopes (38, 40) is implanted in last DSSD or out the DSSD stacks. We may need to add more degrader!

 

Equivalent thickness of W, Pb and Al degraders

   The measured implantation profiles agree with LISE estiamtes for the equivalent change in implantation depth for W, Pb and Al. These were estimated with LISE by comparing change of range in Si for 1mm   degrader of each material (see attachments). Note that W produces a larger change in range than Pb (higher density; according to LISE database).

     1 mm Al: 1.15 mm in Si

     1 mm W: 5.40 mm in Si

     1 mm Pb: 3.05 mm in Si

The current configuration (run Mg401033) gives:

    3 mm Pb + 0.8 mm W + 3 mm Al  = 16.9 mm Si

Probably our best alternative (unless we can go in and rearrange fixed degraders) is:

   3 mm Pb + 1.3 mm W + 3 mm Al = 19.6 mm Si: move implantation depth 2.7 mm upstream

Here is a spreadsheet where you can play with the numbers and create test your own solution to the puzzle: https://docs.google.com/spreadsheets/d/1QJp8t98sT3pExAQb3xtHtAvk4TUDVO6alhbLIaNtx8A/edit?usp=sharing

Entry  Sun Nov 27 03:25:20 2016, TD, [How to] AIDA discriminator thresholds 
The function and setting of the AIDA discriminators is as follows:

                  LEC (20MeV FSR)    MEC (1GeV FSR)    HEC (20GeV FSR)    Function

slow comparator   10keV/unit         500keV/unit       n/a                controls LEC/MEC ADC readout

fast comparator   100keV/unit        5MeV/unit         100MeV/unit        controls LEC/MEC disc readout
                                                                          controls HEC ADC readout


For example, a slow comparator setting of 0xa corresponds to a threshold of 100keV (LEC)
or 5MeV (MEC), and the default HEC fast comparator setting of 0x2 corresponds to 200MeV.

Entry  Sat Nov 26 20:26:06 2016, Liu, AE, Analysis of implantation profile in AIDA imp.jpgpid_corr.png

Here we show the PID plot and implantation depth in AIDA from BigRIPS file 40Mg1012 (1 hr of data from 20:30 in Nov 26th), merged with AIDA files R10_8 to R10_29

The more neutron-rich isotopes have a shorter range in AIDA, and seem to be implanted towards the first layers of the stack. For 40Mg - most exciting case(?) - there is only one count at DSSD1. But comparing to the position of 38Mg, we could deduce that the implantation depth is already good. need more data analyzed to decide if we need to remove a bit of degrader.

Degrader settings: 3mm Pb (at BRIKEN PE shielding), variable of 1mm W (+1mmAl) + 0.3mmW (+1 mm Al)

Attachment 1: DSSD of detected implant for cuts in the PID.

Attachment 2: PID from F8 to F11.

00.33 DSSSD bias & leakage currents OK - see attachments 1 & 2
      FEE64 temperatures OK - see attachment 3

00.34 DAQ continues (RIBF03R1/R10)

      ASIC settings 2016Nov17-10.50.10
 
      BNC PB-4 pulser
      Amplitude 90,000
      x5 attenuator IN
      frequency 25Hz range
      t_r 50ns, tau_d 50us
      polarity -, tail pulse, delay MIN, INT ref

      good events - see attachment 4
      N.B. 5x FEE64s > 100k data items/s - intrinsic/extrinsic noise has changed cf. 0x FEE64s previously

00.50 SyncCheck - see attachment 5
      Two peaks for RIBF-AIDA, one peak for BRIKEN-AIDA => RIBF issue?

      Merge statistics - see attachments 6-11

00.56 All system-wide checks OK - except clock status - see attachment 12 
      Note - clock status fails show bit 2 set

01.02 Visual scaler - see attachment 13

03.00 Beam stopped temporarily.
      File R10_142 @ ~ 1.5Gb.
      Beam returned ~03.06. Near end of file R10_147.

05.57 Bias and leakage currents ok (attachments 14+15).

06.25 R10 (@R10_211) stopped in anticipation of LN2 fill.

07.11 Successfully restarted DAQ after LN2 fill.
      Started run R11.

07.18 Beam stopped to change stripper foil.
      End of R11_1.
      DAQ also stopped as I typed this.

07.53 Beam returned.
      
08.01 R12 started on 1GeV setting to look at suspicious data in high LEC/low HEC ranges.
      Will run this for ~30mins.      
      (NB: Threshold of 0x20 was not changed so...)

(DK arrives on shift)

08.21 Data size of R12 very small, but maybe to be expected as the low gain usually contains ~10k counts which
      is now suppressed? 
      Offline analysis show no implants, even in the low gain portion.  Strange!
      Redo this test again later today if possible

08.50 Stop R12
      Change the medium energy back to low energy

08.55 Start R13 with low and high energy modes
      The data stops writing to disk for some reason

09.05 Switch the degrader condition: was degraders 2 & 3, now degraders 1 & 2
      Liu and Alfredo had found one 40Mg event (it seems we have about 1 such event per hour)
      However, it was only implanted into DSSD #1, so we want to implant 40Mg deeper (N=1 statistics, woohoo)
      So now, 0.5 mm W (+1 mm Al) and 0.3 mm W (+1 mm Al)

09.14 Run takes a moment to begin (data transfer links on FEE 3 and 4 dropped out briefly).  R14 now.

09.39 Data writing stopped. We re-sequence the merger (toggle data transfer on all FEE64s), and start run R15.

09.43 R15 stops writing to disc. All system checks still passed, but not writing.
      Restart merger but lose contact with nnaida14.
09.50 Power cycle FEEs.

10.20 Start run R16 -- garbage
      nnaida13 refuses to calibrate ADCs
      Maybe miscommunication with BRIKEN team?
      When we restart, they need to reload parameters, and then they cannot see our sync (or we are actually not
sending it?)

10.25 Start run R17
      Still the time stamp from AIDA is not visible on the sync check?
      One of the Check ASIC Control tests returned something other than OK
          (sorry, we did not copy it)
          But trying it again (w/o other changes), then it returned the default OK values.
      BRIKEN is not synced with BigRIPS?  They don't know if it gets syncs from AIDA or not
      All AIDA sync checks appear as normal, however

10.36 BRIKEN and AIDA seem to now be synchronized (we did nothing on the AIDA side)
      It is unclear if we are sync'd with BigRIPS.
      Stop this run to get aligned with BRIKEN

10.41 Start R18.  Checks on ASICs and SYNC come back good.
      Degrader settings (not changed): 3 mm Pb,; 0.5 mm W (+1 mm Al); 0.3 mm W (+1 mm Al)
      F11 plastic rate 8 cps
      BigRIPS run 1026; started 10:27

(CG leaves shift)

(TD arrives)

12.28: BigRIPS run number 1028

12.58 Checking the synchronization, and it is not correct.
      R18_28: BRIKEN issues a new synchronization signal

13.25 Merger stops

      Merger error messages for Q 23 (nnaida24) - see attachment 16
      nnaida24 reboots c. 13:31 - see attachment 17

      Request DAQ STOP, restart Merger
      DAQ stops OK
      Request DAQ RESET & SETUP
      R19 started for AIDA, but we never get the full data links (junk)

13.54 nnaida15 did not show data transfer -> merger restarted
      Now R20_0, DAQs look good, BRIKEN issued resync
      BigRIPS run 1028 still

14.00 SyncCheck see attachment 18
      good events statistics - see attachment 19 - rates lower than observed yesterday, not clear why
