OH, TD | Friday May 5th | Relatively painless start-up. Had an issue with firefox where all bookmarks had been forgotten.
All drop down menues in the DAQ did not work.
Kill all firefox processes to restore.
Had to restart DHCP to get the rasp pi working again.
At first no pulser was visible in all p-side FEEs. Cable and BNC adapter on output of inverter were switched out
and the inverter output
was switched from B to A.
After this pulser signals were visible in all ASICS bar NNAIDA 14 ASIC 1. Power cycle was needed to regain this.
No ADC data and no fast discriminator data. Waveform showed baseline at 16K compared to 8K expected.

15:09 Raised slow comparator threshold to 0x40 ~ 640keV for all FEEs and all ASICs
Hit pattern in attachment 27
Statistics - Attachment 28
New adapter boards appear to have improved the amount of white noise at default ASIC settings
This is shown with the decrease in statistics and also in the waveforms.
At default settings the saw tooth patterns still appear in the waveforms though attenuated
with lower frequencies and lower amplitudes.
Further improvements can be gained in reducing the amplitude and frequency of the saw tooth
patterns by changing the Ibias LF feedback value though care has to be taken that the pre-amp
signal is not taken to the rails. Hence FEE 2 has a value of 0xc rather than 0xf like the others.
Hit pattern checked for the pulser by raising the slow comparator threshold to 640keV. The boards that
have been changed show a much more believable rate than those that haven't which are still showing
higher than pulser rates.
16:09 The effect of changing the shaping time on the pulser widths was checked.
Optimum still appears to be at around 8us

10:45 Investigating the large noise in FEE28
First test was swapping the PSU positions of 29 and 30 - attachment 1
PSU order 25, 26, 27 ,28, 30, 29, 31, 32
Little affect on the statistics. 30 remains low and 29 is still high
11:15 System back in normal configuration with 29 and 30 going to original psu units
PSU order 25, 26, 27 ,28, 29, 30, 31, 32
System does seem worse off in this order - attachment 2
11:29 Bias cables core and braid switched between detectors 1 and 2
No noticeable difference - attachment 3
11:44 Switched around cables running to FEE so DSSD1 was running to 29 and DSSD2 to 30
Noise moved with cable. Though DSSD1 seems worse in 29 than it did in 30. - attachment 4
12:00 Cables moved back in normal operation. Stats returned to as they were at 11:15 - attachment 5
13:28 Changed kapton for a new one. No change to stats - attachment 6
13:55 Wiggled rain wire (Technical term) Tripped DSSD 2 bias. Ramped up bias. Noise gone. Mystery not solved. -

OH, TD | AIDA GSI Setup Noise Tests | Currently seems to be a problem with the memory check in the system wide checks that produces the message shown
- attachment 1
DAQ is being run with the following options - attachment 2 and 3
The PSU Temperature readout in aida07 appears to not be working. Shows a permanent value of 160 degC - attachment 4
Water inlet and outlet feel cold so believe it is an artiface
aida07 also appears to quite often take longer to mount than the others. Often coming in 5 minutes later than them.
Only tested aida01 - aida04 for noise as we lacked the required HDMI type c cables to set up a full MACB branch
structure.
We appear to have considerable noise issues in the FEE modules with adapter boards on but no DSSD cables
connected but test input loop and pulsar connected.
The pulsar appears to be the circuit of doom for this noise. With all test input ports connected to a pulsar
chain each FEE is seeing in the region of 800k rate of good events with discriminator thresholds set to 255.
Removing the pulsar cable from the end FEE but leaving the chain in place reduces this to around 500k.
Grounding an adapter board to the copper cooling plate also further reduces this noise somewhat but still leaves
rates of around 300k.
If an adapter board is isolated from the chain so that it has nothing connected to it the rate drops to around
300-400 which is just the rate of the sync pulses.
For the following screenshots aida01 and aida02 are isolated adapter boards.
aida03 and aida04 are connected via lemo cables via the test input to other FEE modules in their chains.
Waveforms for the 4 FEEs - attachment 5-8
Full statistics for the 4 FEEs - attachment 9-12
Good events comparison - attachment 13
It appears we need to provide a low resistance path between the FEE cooling plates like we do in RIKEN.
Currently the measured resistance between FEE 6 and 10 is around 2 ohm.
Also we may need to isolate the pulsar signals themselves
A potential difference of 5mV was also measured between the chassis of the NIM modules and the cooling plates.
Resistance was 0ohm when the power was on. |
