07.44 R42 started following LN2 fill. (BRIKEN computer had some problems, delaying restart.)
No synchronisation with BRIKEN during R42_0.
Re-sync pulse issued and synchronisation obtained 1.2GB into R42_0.
7.55 Big RIPS run 1119

8.55 Big RIPS run 1120: corresponds roughly to AIDA R42_15

09.55 BigRIPS data file 1121
10.00 Beam is stopped for changing stripper foil. Nearly at the end of R42_27.
Previously there was 8. + 0.2 mm of Al on the upstream side of the PE wall
Pb bricks between MUSIC 1 and MUSIC 2 had the width reduced from 7.5 cm by ~1 cm compression on the beam
right side
So the total gap in this location should be
Now we have 5 mm Al between MUSIC 1 and MUSIC 2.
3. mm and 0.2 mm Al is on the upstream side of PE wall.
(Total thickness of Al degraders is not changed, only the distribution of the material around F11.)
(Variable degraders are not moved: 0.5 mm W + 0.3 mm W + 1.0 mm W (+3 mm Al backing))

BigRIPS 1125 (circa 13.21)
15 cps at BigRIPS scaler F11 plastic; network camera for ZDS scaler has 55 cps
(DK return, TD to lunch and PAC)
15.26 BigRIPS setting changes from 40Mg setting to unreacted 41Al setting.
About half way in AIDA R43_27
BigRIPS #1127
F11 plastic at BigRIPS scaler is about 30 cps (doubled from before)
Brho settings:
D6 7.3989 Tm
D7 6.2253 Tm
D8 6.2405 Tm
16.25 Operator calls. The beam is stopped. They don't specify for how long and we don't know the exact
technical reason without native Japanese speaker
Phone rang in the beginning near AIDA R43_41
16.33 They put back the disable access radiation control...beam returns soon?
16.43 R43_47 run in AIDA, beam comes back.
F11 scint scaler of BigRIPS shows around 30 cps as before. (network camera scaler from ZDS shows about 80
cps)
BigRIPS data file 1128
16.58 Naive estimation of the energy loss difference of 40Mg and 41Al from different optics settings
Use D8 Brho of 6.3208 Tm of R21_0
40Mg energy after 8mm Al: 125 MeV/u
41Al " " " ": 140 MeV/u
Use D8 Brho of 6.2405 Tm as above for the present settings
40Mg energy after 7 mm Al: 125 MeV/u
41Al energy after 6.5 mm Al: 142 MeV/u
So, neglecting other stopping materials, the difference between implantation depths could be about 1 or 2
SSD layers towards the front of AIDA.
17.08 R43_53 removed variable degrader #1 (0.5 mm W [+1 mm Al])

CG, AE, TD | Thrus 19th Feb progress | 19/02/15
1000: Check system gives same resolution as yesterday, removing only the Cu braiding connecting and grounding all adapter PCBs (also moved bias braid back to nnaida3).
Pulser FWHM in each FEE... nnaida1 ~800ch, nnaida3 ~110ch, nnaida6 ~2300ch, nnaida8 ~950ch. Rate in 6 and 8 ~5kHz per strip.
Re-added Cu braids, clipping on to LEMO connectors of adapter PCBs.
FWHM and rate/strip in nnaida1,3,6,8 now (respectively): ~600ch and 100Hz, ~120ch and 25Hz, ~2100ch and 6kHz, 1000ch and 6kHz. => small reduction in nnaida1+6
nnaida8 also has non-Gaussian pulser peaks.
No clear effect, but minor improvement and no negative effects mean we will keep Cu braids attached.
1045: Grounded nose to adapter PCB attached to nnaida7+8. No clear effect.
1055: Changed pre-amp reference settings in nnaida1+8.
nnaida1 0x30 -> 0x60. nnaida8 0xb2 -> 0x82.
No clear change. Reverted back to original settings.
1130: Changed to detector BB18 2977-20 and added 241Am (1uCi) and 207Bi (few uCi) sources 2cm from front of detector (see attached photos for arrangement).
Bias set at -100V with leakage current -10.9uA.
Pulser peak FWHMs for each nnaida are: #1 ~600ch, #3 ~150ch, #6 ~1300ch, #8 ~ 700ch. Minor improvement over previous detector.
1345: nnaida3 still much more well behaved than other nnaida. To test if kapton cables are source of issue, swapped kaptons for nnaida3+8 at FEE end.
Peak FWHMs and rates for nnaida3+8 having swapped cables are: #3 ~700ch and 300Hz, #8 ~200ch and 30Hz.
=> noise moved with kapton! Kaptons could be the issue. (For completeness, FWHM in nnaida1 ~800ch and nnaida6 ~1100ch.)
1435: Disconnected kaptons at detector end (still connected to FEE adapters).
Pulser FWHMs and rates/strip per strip now: nnaida1 - ~250ch and 25Hz, nnaida3 - ~120ch and 25Hz, nnaida6 - ~160ch and 25Hz, nnaida8 - ~120ch and 25Hz.
Waveforms for all nnaida looked similar and with little noise => no way of telling a 'bad' cable from a 'good' one, just from FEE + cable (without detector).
Current cable configuration/pairings: nnaida1-kapton A, 3-B, 6-C, 8-D.
Kapton B shows no alpha/beta spectrum from sources in 1.1.L, a problem which tracked across to nnaida8 when cables were swapped => suggesting break in cable for this channel.
Waveforms in all nnaida look relatively noise free (nnaida1 slightly noisier) and as expected.
1520: Changed some of the kaptons to check all were functioning properly. Kept nnaida3-kapton B combo as this was working as expected from DL tests.
Changed nnaida1 A->E (neither isolated), nnaida6 C->F, nnaida8 D->G.
After removal. noticed outgoing kaptons C+D did not have "Isolated" label on them (B does).
Without connecting new cables to detector, FWHMs and rates/strip in all nnaida ~130-150ch and ~25Hz, respectively.
1545: Connected kaptons to detector 2977-20 and with alpha+beta sources 2cm in front of detector.
Bias connected via nnaida6 (-ve core) and nnaida3 (low V ref braid). nnaida3+8 grounded.
nnaida-kapton pairings now as follows: nnaida1-kapton E, 3-B, 6-F, 8-G.
Pulser FWHMs and rates/strip now: nnaida 1 - ~190ch and ~60Hz, nnaida3 - ~250ch and ~60Hz, nnaida6 - ~180ch and ~40Hz, nnaida8 - ~350ch and ~100Hz.
Above rates seem sensible considering we have 25Hz pulser going into FEEs, plus alpha and beta sources.
MUCH better than previous! (apart from nnaida3 which remains about the same)
Further more, rate spectrum for each nnaida shows slow decline in rate with increasing bin number. Expected as 241Am placed centrally and outer strips will see lower rate as more alphas are stopped due to path travelled.
1645: Saving data to file with system configuration: Am+Bi sources, EBFG kaptons, Cu braid grounding between adapters and nose grounded to nnaida7+8 adapter.
File - /TapeData/Feb2015/Run1_*.gz.
Run stopped at 1715.
17:40: Providing one pulser signal to BRIKEN VME crate, which is in the same main bias supply as AIDA. Start a new run to check things are not changed

Patrick Coleman-Smith | Testing Version 8 | 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.

OH | T9 Test Bench | T9 test setup at Daresbury was powered up and noise levels were checked using a pulser peak.
A 1V peak was used. For most channels this corresponded to a peak position at around +-11000 from the zero point at 9000.
An example of this is shown in attachment 1 showing the peak in nnaider 11, ASIC 4, ADC 11.
It was also observed that for both nnaider 11 and 12 (FEE modules corresponding to negative signals) that channels 2, 56 and 59 were not contributing to the rate. See attachment 2.
Upon investigating the missing channels ADC spectra the only apparent issue appeared in nnaida 11 ASIC 4, ADC 8. Which is plot 4.7.L. Here we see the peak much higher coming in at around channel 63000. See attachment 3.
The remaining missing channels in the rate plot appear to have normal amplitudes with maybe slightly higher noise. FWHM of ~60 as oppposed to ~18. Discussed more below.
Also done was a noise measurement across the all the ASICs. To do this an ADC was chosen belonging to each of the ASICs and the pulser peak location and FWHM was recorded. The reaults are as shown below.
FEE# ASIC/ADC Centroid Location FWHM
11 1.8 42951 19.38
11 2.8 41012 17.48
11 3.8 41929 20.01
11 4.8 41302 17.88
12 1.8 41830 17.38
12 2.8 41119 16.01
12 3.8 42669 18.30
12 4.8 41811 15.21
13 1.8 24329 15.05
13 2.8 24034 13.64
13 3.8 24209 15.79
13 4.8 24607 13.29
14 1.8 24650 16.19
14 2.8 24618 14.12
14 3.8 23934 15.04
14 4.8 22584 14.36
14 4.8 22584 14.36
It was seen that the noise was fairly low which is to be expected as there were no dtectors connected and only a short length of kapton cables connected to the board. |
