Analysis of the pulser run R9_52 -> R9_74 has shown no major losses in terms of apparent broken bond wires.
The large gap in FEE64 29 can be explained by an ASIC dropping out: See https://elog.ph.ed.ac.uk/AIDA/730
Another odd trend appears in the channels relating to DSSD 8 on the x side. - attachment 5
The pattern shows one strip on one strip off for the first 32 strips.
nnaida18 is also the FEE which is running at a much higher rate during this run. - attachment 3
I'm not sure that I believe that these channels are actually relate to broken bond wires.
Here are the hit patterns for the 8 DSSD - attachment 4
Attached is also the x and y histograms for DSSD 8 which shows a weird pattern - attachment 5 |

16.11 The cyclotron and BigRIPS condition are now restored and we have good beam
Count rate at F11 plastic is ~8 cps
At F8, they are focued on 41Al (D5 Brho = 7.5235 Tm)
At F11, they are focused on 40Mg (D8 Brho = 6.3208 Tm)
Presently around Run R9_19
3mm Pb is on the exit window of the first MUSIC at F11
All variable degraders were out (that is not what we intended to have...see next note below)
16.35 The variable degraders were not in the positions we thought. Now we make it as follows:
Variable degraders 1.0 mm W (+1 mm Al) and 0.3 mm W (+1 mm Al)
R9_24 just began
18:00 Beam stopped for stripper foil change
Moved Pb degrader downstream, from window of MUSIC1 detector to hole of polyethylene shield in front of BRIKEN.
18:12 Stopped AIDA DAQ at run R9_43 (Ge filling will start soon)

'want first SYNC' from merger
lost contact with nnaida19 - restarting merger
TclHttpd server on nnrpi1 crashed - restarted remotely
unable to power cycle - need to check fuses when next obtain access
whilst waiting boot aidas1
F11 rate c. 450Hz
AIDA veto plastic c. 3200Hz
07.30 R7 started with beam.
07.38 Beam stopped.
R7 continues.
08.12 Beam returned to F11.
File R7_9
08.50 Beam stopped.
Start of R7_17.
Using implantdecay.f saw no HEC events in any DSSD. Removed 2mm of Pb degrader.
We re-insert all the variable Al degraders (for now) for safety. We can remove them again when the beam
comes back, as necessary.
Secondary beam current expected to remain at ~50cps.
Now no beam for ~1hr.
10.15 Beam comes back
There was a minor delay to get the beam back from some accelerator issue (SRQ issue I am told)
F11 plastic rate is about 10 cps, still I can see nothing in AIDA low gain
Main exp. team confirms several 40Mg events within minutes, and makes jokes about old Nature paper with 10 days of
data to do that.
10.25 Trying to find AIDA's implants, using MIDAS Sort in online mode
Removed the variable degraders, one-by-one. Still nothing? (this is now circa file R7_36)
Is there a possibility that the "low gain" setting of the ASIC is too high energy for something like 40Mg?
We try to check the implant rate with the AIDA veto plastic
During this time, we moved degraders in and out, several times, watching the oscilloscope and visual scalers by
video link in F11
10.39 We check some scalers of the dE before AIDA (including F11 x plastic behind AIDA)
We can see a reasonable effect as expected for these detector count rates
The count rate never exceeds about 50 to 60 cps at maximum for dE
I don't trust MIDAS Sort in online mode
it is known to show factor 10 or less of the real rate, previously)
Check the data file R7_37 -> may show 1 to 2 Hz
We should decrease the low gain (heavy ion) threshold or dynamic range for the ASICs?
But DK is not an expert of that, and doesn't want to cause AIDA to cease functionality...
11.03 Checking runs later than R7_37 (i.e. _38 to _42)
Never see anything. R7_37 must have been taken with some amount of degraders in
We surmise that the ions are mostly punching through AIDA, owing to low Z.
11.05 We put in the 0.5 W + 1 mm Al degrader back, to see if we can get back the condition of _37...
R7_44 after a short delay should have this condition.
There can be 1 cps or something, though with small statistics it is hard to say...
It seems to be definitely non-zero though, compared to some runs like _38 to _42
11.10 Add the 1.0 W + 1mm Al (with the 0.5 W and 1 mm Al) degrader
R7_45 begins ~400 MB before this time.
We can see some kinds of definite hit events **with low stats** (1 to 2 Hz in several detectors in some data blocks)
It seems to be, if all degraders are out, that the beam punches through AIDA, and dE is below the thresholds
Of course, the count rate at F11 is only 10 cps, so we cannot conclude much with strong confidence...
11.17 Remove all variable degraders again (near halfway point of R7_46)
We need a decent LISE++ file to get a clue of where these ions are stopping...!
11.42 Beam is stopped because one of the cyclotron RF systems is down.
This occurs around the middle of file R7_50
12.40 Still waiting for beam. I try a more definitive analysis of R7_45
Partial disk analysis of file R7_45:
First part of data look like this:
*** DSSSD # 1 count: 4 old count: 2 dt: 1.06 s HEC rate: 1.89 Hz
*** DSSSD # 2 count: 1 old count: 0 dt: 1.06 s HEC rate: 0.94 Hz
*** DSSSD # 3 count: 0 old count: 0 dt: 1.06 s HEC rate: 0.00 Hz
*** DSSSD # 4 count: 0 old count: 0 dt: 1.06 s HEC rate: 0.00 Hz
*** DSSSD # 5 count: 0 old count: 0 dt: 1.06 s HEC rate: 0.00 Hz
*** DSSSD # 6 count: 10 old count: 10 dt: 1.06 s HEC rate: 0.00 Hz
Notice that we get 10 total counts in DSSD#6, and practically 0 in any other layer (2 in DSSD#1)
Now, as the analysis progresses, we do not increase the counts in DSSD#6, but we start to see events in other layers
*** DSSSD # 1 count: 128 old count: 128 dt: 343.81 s HEC rate: 0.37 Hz
*** DSSSD # 2 count: 115 old count: 115 dt: 343.81 s HEC rate: 0.33 Hz
*** DSSSD # 3 count: 91 old count: 90 dt: 343.81 s HEC rate: 0.26 Hz

Notice how only 12 counts in DSSD#6 (two new counts) but 128 counts in DSSD#1 (126 new counts).
We can conclude that with 3 mm Pb (fixed), and 0.5 mm W and 1.0 mm Al, some of the beam is stopping in DSSD #6, and mostly
punches through.
Then, when 1.0 mm W and 1.0 mm Al are added, we shift the implantation to the beginning of AIDA (or some in the air
before AIDA).
So, we should try the 1 mm W (+1 mm Al) and 0.3 mm W (+1 mm Al) once the beam returns.
13.34 Stop run 7.
Change the medium/low energy selection on ASIC control from 0x0 to 0x1 (from low to medium energy mode)
(Already, the high energy setting is 0x2 and we cannot decrease it)
Start run 8. It looks okay, though of course now data rate becomes much smaller.
13.36 Beam is now on again. F11 rate has decreased 1 order of magnitude (now it is 0 to 2 Hz)
14.00 As expected, data rate becomes quite low, as the low energy mode has typically many events (10kHz or so)
But now we don't see anything in the high energy mode as before
3 mm Pb remains in, and variable degraders are all out (mistake...we meant for some to be in)
Strange! But the beam at F11 does not seem to be the same rate as before the cyclotron issues...
Realized that someone was checking the beam at an earlier focal plane and that F11 has no beam...
(Post-dated note: forgot to hit "Start ASIC Readout" --- duh oops.
RUN 8 IS JUNK, AS NO ASIC READOUT BY USER ERROR (DK)
14.12 Stop run 8. Change the medium energy mode back to low energy mode of all ASICs. Restart as run 9.
But the merger data links don't alternate colors when I reload the merger screen. Is it bad?
Data rate is still very low, but that doesn't make much sense.
Okay, now I start ASIC Readout! Woohoo!
But it seems some magnetic dipole of BigRIPS must have an improper setting, explaining the 1 cps rate at F11...

1130: Rotated forward water inlet connection to point towards rear of AIDA stand to remedy mechanical
conflict with EURICA support frame - see attachments. During drain and re-fill of Julabo FL1106
recirculating chiller no evidence of sediment in, or discoloration of, the water. Coolant loop closed
and tested OK.
CG installing (new, production batch) second and third MSL type BB18(DS)-1000 detectors to stack using
the new FCT reduced capacitance 0.9m, 68-way to 68-way, flexible Kapton PCBs - see attachments.
1200: Installed two new BB18 detectors (3131-11 and 3058-09) to nose mount.
Modified isolated kaptons labelled and number 1 and 5.
Source (207Bi) mounted upstream of first detector approx 5-10mm away.
Configuration - 3131-11 (#1) furthest upstream, 3058-09 (#2) in middle, 2977-20 (#3) at rear, followed by
10mm of Al.
1800: Cabled everything up.
3131-11 connected to nnaida10+6 (p-side) and nnaida11+16 (n-side). HV from single supply.
3058-09 connected to nnaida2+5 (p-side) and nnaida4+7 (n-side). HV from ch0 of quad supply.
2977-20 connected to nnaida1+14 (p-side) and nnaida3+8 (n-side). HV from ch1 of quad supply.
Typical resistance of new kaptons ~6.5 ohm.
Typical resistance of old kaptons ~3.2 ohm.
Makes sense if track width has been roughly halved, doubling resistivity.
At +100V bias:
- 3131-11 has leakage current 5.88 uA.
- 3058-09 has leakage current 3.82 uA.
- 2977-20 has leakage current 10.99 uA.
2000: Carried out brief pulser test of all connected modules.
Many spectra exhibit double-peaking of the pulser peak or otherwise non-Gaussian peaks.
Of the ones the have single Gaussian shaped peaks, many now have much larger FWHM than previously observed. |
