Powered system up with 4 bare 45cm kaptons connected and nothing seems to have changed from where we left last night

Waveforms in nnaida11 look good and peak widths in nnaida11 1.8.L and 1.10.L are ~70ch.

Turned off flash ADCs for all FEEs by setting Q8_transfer.vhd: 0xa00, offset 0x00, to 0 to assess any affect they may play in the observed noise

no obvious change in peak widths for nnaida11

turned all back on by resetting value of offset 0x00 to 1

Measured RMS deviation of waveform baseline for nnaida11 with 45cm unshielded kapton connected by sampling waveform every 10 samples over 100 samples, i.e. every 200ns for 2us.

1.4.W      -     mean:    8612.9            st. dev.:     20.5

1.6.W      -     mean:    8548.9            st. dev.:     16.6

1.8.W      -     mean:    8900.8            st. dev.:     16.2

1.10.W    -     mean:    8744.5            st. dev.:     15.0

Removed kapton to check intrinsic RMS deviation of pre-amp using the same method

1.4.W      -     mean:    8666.8            st. dev.:     4.7

1.6.W      -     mean:    8586.6            st. dev.:     2.0

1.8.W      -     mean:    8918.7            st. dev.:     3.2

1.10.W    -     mean:    8782.3            st. dev.:     4.2

These results are consistent with the pulser peak widths observed with/without Kapton PCBs attached

Make a makeshift screening plate for the adapter PCBs using the Cu tape -> widths in nnaida11 all slightly worse but still comparable.

Connected detector using 4 45cm kaptons (gnd via nnaida13) and baised via nnaida12+13 to +200V with a leakage current of 5.16uA (Room temp 24.2oC)

Initially observed very noisy waveforms but grounding adapter PCBs together improved the noise slightly but not to an acceptable level (see attachment 2+3).

Measure the peak width as a function of shaping time:

t_shape:             0.5   |   1.0   |   2.0   |   4.0   |   8.0

FWHM (ch):     308    |   352  |  345  |   252  |  130

Throughout, the peaks were non-Gaussian and double peaked with single peak widths ~50-70ch.

Pickup effect rather than white noise?

Shielded kapton to nnaida11 with Cu tape and found noise to decrease slightly when grounded to LEMO connector on adapter PCB - bursts reduced in amplitude but persistent periodic noise remained (see attachments 4+5).

Changed grounding around (adapters to NIM crate, adapters to detector box etc) and observed no noticeable difference.

However, removing jumpers grounding PCBs to FEE cards and the grounding between the adapter PCBs makes the noise worse.

Shielded 3 more 45cm kaptons and connected detector -> no leakage current.

Found several pins on 2 kaptons to be broken. Will get these fixed in Edinburgh for use next week.

Reconnected old kaptons and system is as expected - slower rise time in waveforms but reasonable levels of noise and expected peak widths (see attachment 6).

This morning PC-S changed firmware and DAQ software to that of the RIKEN setup

Firmware version /MIDAS/AIDA/FEE_Riken_Apr14_26.bin

DAQ software has been changed from AidaExecV8 to AidaExecV7

nnaida12 is not playing ball -> ASIC4 has stopped outputting any data and ASICs2+3 are missing multiple channels. Not running hot

Suspicions over the power cable as the source of the problem (previous nnaida12 developed noisy ASICs) and tests found this not to be an issue. Neither are the MACB HDMIs as they were swapped for new ones last night.

Then changed the adapted PCB to see if that was a possible cause. No change -> FEE or mezzanine problem?

With old kaptons attached, peak widths in nnaida11 are ~180-190ch with shaping time 2us. Increasing this to 6us brings FWHM to ~170ch, and increasing further to 8us reduces the FWHM to ~140ch.

FAO PC-S -> After lunch, upon clearing the spectra, nnaida12 stopped responding (terminal screenshot below - attachment 19). Brought system to halt. Power cycling resolved the isssue.

A series of tests over the afternoon found peak widths to vary only by ~10-20% when the second length (detector end) of kapton was removed. Removing the connecter PCB showed no improvement over this.

However, removing the Cu tape put on as shielding, reduces the FWHM by a factor of 3.

see nnaida11_wav_newCable.png (attachment 17) for before waveforms -> the Cu tape is clearly doing something we are unaware of.

Attachment 18 shows improvement in just removing the Cu tape.

Re-adding connector PCB, increased widths by ~5-10% and re-adding second length of kapton increased widths by x3-4.

Second length of kapton was tested on its own and was found to have roughly the same widths as the first length, no issues with this cable -> increase in FWHM just due to increased capacitance (possibly...)

Connected a 45cm kapton to each FEE, 3 with the ground connection broken, and the grounded one connected to nnaida13 (attachment 23).

Varied shaping time and found 0.5us to consistently provide lowest FWHM (summary graphs to follow).

With just one length (+connector PCB) of kapton connected to adapter PCBs, waveforms all look very good, too good to explain the higher than expected FWHM.

Upon connecting 90cm of kaptons, noise creeps in to waveforms. Also observed reoccurring periodic transients in some waveforms (attachment 20).

Rise time with new kaptons connected (45cm) noticeably faster that with the old cables -> new show rise time of ~140ns, old cables has rise time ~3us.

To do tomorrow:

connect detector to FEEs using 4 45cm kaptons, assess affect on FWHM.

Upon starting system with nothing connected beyond adapter PCBs, observed pulser peak FWHM of ~12-15ch in nnaida13+14 and ~15-18ch in nnaida11+12

All newly shielded new kapton cables passed continuity tests between drain wire and Cu tape.

Throughout all tests, grounded cable has been connected to nnaida13. All other nnaida have ground isolated cables.

Initially, upon biasing, leakage current reached 50uA at ~2V HV and tripped.

After much searching, found one of the drain wires from the kaptons to be touching the core of the HV cable.

Tidied all drain wires and made sure none were touching anything they shouldn't.

Bias ramped up successfully to +200V with leakage current of 5.630uA @ room temp ~25.5oC.

Very noisy waveforms to begin with, notes Cu tape on kaptons was in contact with the Al housing for the detector.

Isolated kaptons from Al housing with black tape and the waveforms became much less noisy, but still not as calm as expected.

Connecting Cu covered kaptons with croc clips made this problem worse. However, grounding adapter PCBs together improved the waveform noise.

FWHM with new cables ~200-300ch, much worse than previous cables.

Reconnected system with old kaptons and they now see FWHM of ~200-300ch, as opposed to ~100ch observed earlier in the year.

What has changed?

Waveforms are smoother with old kaptons, but still not as flat as previously observed.

Had some issues with waveforms not being output by FEE cards and ASIC4 of nnaida12 has failed to Check/Load and is not outputting any data.

Standard ASIC parameters throughout, with shaping time of 0.5us.

New Kapton PCB design (2x 0.45m + inter-connecting PCB, no ground plane layers)  under test with small system in T9.

3 cables modified to remove ground connection.

When just connected to system and BB18 2998-20, with no additional grounding or shielding of the cables

and bias of  +200V (leakage current  +6.2uA, ambient temp +27 deg C) to nnaida14, we observed average pulser peak widths

of ~250ch FWHM

Waveforms were just noise.

Added heavy duty copper braid between adapter PCBs, the small metal box for the detector and Cu tape and drain wire to the kapton connected to nnaida14.

This reduced the peak widths to ~160ch FWHM

Adding grounding between the adapter PCBs and the NIM bin chasis increased the peak widths.

Waveforms for nnaida11-13 remained unchanged, but expected (albeit noisy) traces could be seen for nnaida14).

        ------> Patrick: with ASIC1 waveforms for all nnaida turned on, we found they would occasionally stall for some. e.g. of 4 being observed, upon update, only 1 or 2 actually would. Stop-Go did not resolve this. Load/check ASIC resolved issue.

nnaida14 developed double peaking of pulser peak.

Note waveforms exhibit significantly faster risetime than previous Kapton PCB variants => lower C, as expected

A table summarising the run information within the lab book and ELog for Apr-May.

 I have attached a document describing the new format of the Discriminator Information data item used in Version 8

The attached plots show the time-stamp data in the EURICA files with PID information (EventInfo.timestamp). The
timestamp value should correspond to the correlation scaler included as info_code==8 in AIDA. 

The plots show time-stamp vs entry number in the TTree of the Root file, with the events in groups of about 10
*.root files counted consecutively. To map entry-number to data file use informatino of number of entries per
file in the lines bellow (output of analysis script). NOTE: label for plots in right colume is wrong, trigger
type=3 (pulser) in stead of 2.

The final three plots (pulser_dts_go4_3022*.png) show the time difference between two sequential data points of a
given trigger type (fBit==2 or 3). The value that would correspond to the external scaler (fBit==3) has a peak at
about delta(ts)= 1.7 sec, but also a lot of events with a distribution centered around a smaller value of
delta(ts)~ 10 msec! One can also see the deadtime at about 300 usec at a smaller scale. The units for the
time-stamp are 1-ns.

A plot of a similar distribution for the data in AIDA shows that the peak of the correlation scaler has, in this
case, a very narrow distribution, with a frequency of ~43.5e6 x 40 ns (would agree with Go4 data from EURICA).

When scanning the files the analysis script (attached) skips a given number of entries (~100) to speed up the
analysis.

I have installed Version 8 of the AidaExec program and FEE_GF_Feb15_6.bin for the VHDL on the system in T9.

On the whole the new firmware operates successfully.

I am now pursuing a few niggles.

I have disconnected the detector in order to have a deterministic set of data through the system.

If the system is required for other tests please let me know and the V7 setup can be restored quite quickly.

Unable to replace PCL Kapton PCBs with FCT Kapton PCBs. 
FCT Kapton PCBs exhibited either a high resistance short
(15v/50uA) or expecte diode response as voltage increased
from zero until ~20-30V when leakage curent abruptly increased
to CAN N1419B OVC limit (curremtly 50uA). Return FCT Kapton PCBs
to Edinburgh for continuity/short tests in the automated tester
in the electronics workshop.

 Hi Tom,

Please could you photo the power supply cabling and the MACBs.

Hope i'm not too late,

Thanks

Patrick
