Quote:

FEE64 module aida09 global clocks failed, 6
 Clock status test result: Passed 13, Failed 1

Understand status as follows
Status bit 3 : firmware PLL that creates clocks from external clock not locked
Status bit 2 : always logic '1'
Status bit 1 : LMK3200(2) PLL and clock distribution chip not locked to external clock
Status bit 0 : LMK3200(1) PLL and clock distribution chip not locked to external clock
If all these bits are not set then the operation of the firmware is unreliable

 

FEE64 module aida02 failed
FEE64 module aida06 failed
FEE64 module aida09 failed
FEE64 module aida10 failed
FEE64 module aida13 failed
Calibration test result: Passed 9, Failed 5

If any modules fail calibration , check the clock status and open the FADC Align and Control browser page to rerun calibration for that module

 

White Rabbit error counter test result: Passed 14, Failed 0

Understand the status reports as follows:-
Status bit 3 : White Rabbit decoder detected an error in the received data
Status bit 2 : Firmware registered WR error, no reload of Timestamp
Status bit 0 : White Rabbit decoder reports uncertain of Timestamp information from WR

 

FPGA Timestamp error counter test result: Passed 14, Failed 0
If any of these counts are reported as in error
The ASIC readout system has detected a timeslip.
That is the timestamp read from the time FIFO is not younger than the last

  744   Thu Nov 13 10:14:50 2025 JB, MPNoise conditions after removal of bPlast cabling

JB has removed unnecessary cables and items from the snout and platform:

- the bPlast cables and booster boards were removed

- crate below the AIDA frame was disconnected from the power supply

- BB7 cables were removed

- power supply for the booster boards was removed

 

We switch on the system and check the noise conditions.

We started up. BIAS OK. TEMPS OK.

Thresholds initially set to 100 keV.

Rates in all FEEs are > 200 kHZ. Attachment 6.

We then checked the pulser peak widths in aida14. --> 192 channels with 1 V 1x attenuation. at 700 keV threshold (attachment 3). At 100 keV threshold the peak width was significantly higher!!! ---> 385 channels (attachment 2)

We checked the rates in the FEEs with the 700 keV thresholds (attachment 11).

Furthermore, we checked the constant noise that appears to be present in the y FEEs aida02,04,06,08. This can be seen in attachment 8 and has been noted in previous elogs https://elog.ph.ed.ac.uk/DESPEC/727

Info on current status of ion catcher: vacuum system is ON, electronics is also on (RF ~2MHz) on the side opposite to the DESPEC setup

  743   Fri Nov 7 12:30:30 2025 JB, GB, MPPulser walkthrough for source tests.
13:30 We are going to do the pulser walkthrough for the the source tests.

We are wrapping the snout in some copper first to further establish a better connection with the ground.

2025Nov07-13.55.01 is a setting with 100 keV threshold across all FEEs.

We got the DAQ running, TEMPS ok and biased OK. We execute the pulser walkthrough as follow:

10x attenuation - 10V -> 1V in steps of 1 V

/lustre/despec/aida_sourcetest_2025/raw/

pulser_wt_10V - 10V

pulser_wt_9V - 9V

pulser_wt_8V - 8V

pulser_wt_7V - 7V

pulser wt_6V - 6V

pulser_wt_5V - 5V

pulser_wt_4V - 4V

pulser_wt_3V - 3V

pulser_wt_2V - 2V

pulser_wt_1V - 1V

Data taking stopped and we turn off the system to a safe state.

Initial analysis of the raw ADC spectra can be seen in attachment 4 & 5.

  741   Thu Nov 6 12:58:09 2025 NH207Bi source test - data taking
Restart AIDA

aida06 took three attempts to boot today :(

All system checks OK, ASICs aligned

Run DAQ without merger - looks okay, all FEEs working

When connecting to merger aida15 drops connection, solution restart merger

Aida13 not sending data - do an ASIC check/load

Finally all DAQs send data, merger is happy with all 16 FEEs

Open run R6 on disk

  740   Wed Nov 5 13:23:38 2025 JB, MP207Bi source test - FWHM tests
14:10 started up the DAQ. HV and TEMPS OK.

Peak threshold with 1V pulser measured at ~ 175 ADC channels. Attachment 3.

14:24 DAQ stopped and detector debiased. We are going to do the following:

1. Cover the snout with a black cloth to check if it is light tight!
2. Disconnect the detector signal cable from the FEE64 adaptor card of aida14.

We put a black cloth cover over the snout, but pulser peak width remained the same ~161 ADC channel. Attachment 4,5.

We disconnected the cable from aida14 and the FWHM pf the pulser is ~15 ADC channels (as expected)

Wrapped the snout with more copper tape at the point where the PCB ground makes contact with the snout to ensure better contact, this seems to improve the FWHM to ~95 ADC channels

  739   Tue Nov 4 17:29:28 2025 MPBi207 source data, 700keV

Anydesk has crashed. I am not able to set it up again. I switch off bias and fees

Quote:

Some FEES were not acquiring data for some reason we could not understand. We lowered the thresholds to 200 keV, then rose them again to 700 keV. It seems they are now acquiring. We start data taking again.

Quote:

- Bias and basic checks: the pulser FWHM appears to be ~170, which is the same we have obtained at the end of last week.

- Initialised the Merger and Tape server

- loading of settings: EXPERIMENTS/AIDA/2025Nov03-16.21.44

- slow comparator thresholds set to 700 keV for all X FEES

- y FEEs disabled in the discriminator

- Starting data taking with following details:

MIDAS data in: Bi207Centre_700

MBS data in /lustre/despec/aida_sourcetest_2025/raw started from lxg3138 on screen ('AIDAdaq')

 

We take data overnight in this configuration and continue the grounding checks tomorrow
