Probe PSU output with 'scope again and 10X probe Use a AC mains scope as was available, means referenced to ground of AC, but should be ground of platform (and hence Fee64) Figs 1-3: Traces of PSU outputs (5V, -6V, 5V Return) with 10X probe, 1 MOhm impedance AC coupled Lots of fluctuation and jitter Figs 4-6: DC 1MOhm output from all 3 power rails Fig 7-8: Small "loop" using probe and observed scope spectra. After lunch ideas: - Try again with 1X probe attenuation, maybe record output to USB - Remove unconnected MACBs from master -

Firefox browser proxy setting changed to 'Auto-detect proxy settings for this network' ( Firefox -> Edit -> Settings -> Network Settings -> Settings )
397	Tue Mar 1 08:29:19 2022	OH, NH	Findings from the upgrade to centos7 from SL6
Required packages not included as default csh (For running MIDAS scripts) xinetd (Runs the rdate server for the FEEs) Telnet (Communication with the FEEs) dhcp Configuration changes FEEs uses NFS2 which is no longer enabled by default Must edit config in /etc/nfs.conf to uncomment the following lines: [nfsd] vers2=y /etc/xinetd.d/time-stream must be edited by uncommenting disable = no Many services such as xinetd and dhcp will not automatically start at startup following a restart of the system To enable this must enter `systemctl enable dhcpd` or `systemctl enable xinetd` Likewise can check status with `systemctl status $SERVICE_NAME` Also need to check the firewall status of the ethernet port connected to the FEEs. Easiest solution is to set the port to be trusted Optional extras For top bar icons similar to SL6 can use the gnome extension "Frippery panel favorites" Then just need to create desktop icons for each of the startup scripts within /usr/share/applications - Attachment 1 Can also add screenshot to this - Attachment 2 Gnome tweaks also allows the number of workspaces to be changed Also recommend setting workspaces to span displays

It is possible to get good rates with the fast discriminators with a few hot channels mask in aida03 and aida10 Threshold is 0x20 = 3.2 MeV They can be tested in beam to see performance, especially note the first setting will involve alpha emitters to check in AIDA All FEEs: AS01 01, AS3 07 10 13 are masked aida03: AS0 12 and 14 are masked in addition aida10: AS1 10, 11 and AS2 05, 06 are masked in addiction

A figure showing the FEE64 numbers (a previous diagram had 2/6 and 4/8 on the wrong side of the DSSD) and the wiring of pulser/HV Also the jumpers connected to the boards As always diagram is looking with direction of beam Edit: Figure as signals (HV/Pulser) come from the beam right not beam left Otherwise OK

388	Thu Oct 21 16:18:51 2021	OH	FEE and Adaptor board groundings
During investigations into the noise today by NH and OH a couple of findings were made on the grounding of the FEEs and Adaptor boards. - The adaptor boards have no connection to the FEE ground over the ERNI connector - Currently we are providing one via a ground cable between the FEE Al cooling and the Lemo ground on the adaptor board - The Al cooling plate is not electrically isolated from the copper plate on the ASIC and both are connected to the electrical ground on the FEE - Verified with 0 resistance between plate and HDMI ground shield - The FEE is electrically isolated from the frame but when cabling is connected they show 0 resistance - With electrics disconnected but water still connected they show 200kOhm - With the bias core going to FEE14 and the braid going to FEE8 better performance in FEE14 is obtained by disconnecting FEE8 adaptor board from the ground - The cost of this is the rate of FEE8 goes up to 300k - It is essential to have the adaptor board ground on the FEE ground but unsure why having both adaptor boards connected to their respective grounds makes one worse - The resistance between all FEEs is not zero. Some show a 5Ohm and some show a 35Ohm resistance between each other

Some show a 5Ohm and some show a 35Ohm resistance between each other > The adapter boards have ERNI ground pins, and the FEE64 has a grounded plane on its ERNI connector, unfortunately the orientation means the ground pins do not touch the plane on the FEE64 and hence no contact is made Would require installing board "upside down" but then the ASIC connections would be wrong. A new adapter board layout would be necessary to correct this Tomorrow will investigate direct connection of all FEE64s to mechanical ground via dedicated copper cable. Currently FEE64s get ground via Pulser(->NIM) ((weak ground)), HDMI(->NIM) ((possibly?)) and Power(->PSU) (primary grounding) HV Bias is floating at NIM side and so does not provide ground path (intentional) TD may have ideas to isolate pulser from AIDA FEE ground Unsure if HDMI ground is a problem The ground quality via the power may not be ideal over long cables of relatively thin wire. (5 * 20 AWG) and then unsure how ground of PSU connects to mechanical ground Explicit grounding may help keep resistance between FEEs < 1 Ohm. Will also mount a DSSD and see situation without pulser, with/without mechanical grounding and maybe with various LK jumpers.

All 12 FEEs powered up, and temperatures are OK. Passed ASIC checks and system wide checks - now checking cabling and to mount snout.

AIDA has 8 FEEs and 1 DSSSD Aida08 (HDMI#12) had no WR again, I moved it to a different MACB and now it gets WR The MACB (currently with jsut HDMI#10) seems issues, check/replace the upstream HDMI and thent eh MACB (after dry run!) DSSSD#1 biased to -120 V, leakage current 5.6 uA (fig 1) (also on Grafana) Temps OK fig2 System Checks (fig3-5) Clocks OK aida07 fails calibration, others OK WR OK (aida04 0x10, seems OK) FPGA OK Did "Synchronise ASIC clocks" to align ASIC clocks (Notes for scalers: SC41L HDMI 5, SCI41R HDMI 9) 18:12 FRS is taking beam, AIDA is powered off and unbiased

12.51 - detector bias and leakage currents - detector 3 has no current - other detectors ok 13.13 - tried changing from HV3 cables to HV4 - still open circuit - tried different permutations of moving HV-4 braid and core cables (high voltage to ground connections) (dssd3) (all directions defined as if looking upstream) - core -> bottom, braid -> left open - circuit - core -> top, braid -> right trips at 8V - core -> bottom, braid -> right open - circuit - core -> top, braid-> left trips at 8V - removed jumpers - still trips 13.36 - testing continuity of bond wires on dsssd 3208-14 & 3208-15 - observe 20 ohm resistance on p+p and p+n bond wires 19:41 - dsssd 1 and 2 not biasing, 3 ok. - changed bias configuration -> HV core 1 & 2 now on top, braid on right - ribbon cables for DSSSD #1 & #2 p+n junction strips down were misaligned - all detectors biased succesfully HV cable configuration (looking upstream): HV-1 Core -> top-inner (FEE 1) HV-2 Core -> top-middle (FEE 5) HV-3 Core -> bottom-outer (FEE 11) HV-1 Braid -> right-inner (FEE 2) HV-2 Braid -> right-middle (FEE 6) HV-3 Braid -> left-outer (FEE 12) Attachment 3 - rough sketch of HV cable configuration, looking upstream.

639	Wed Jun 5 08:34:47 2024	JB. AM, MP, MY	Detector bias tests
We are trying to bias each system on its own and in sequence biasing each other detector system to see the interdependence. HV OK. TEMP OK. Attachment 1 &2. 9.43 bPlast unbiased, BB7 unbiased. Attachments 3-6 is the noise situation with only AIDA biased (bPlast was biased but turned off after AIDA was biased.) 10/16 FEEs < 20k noise. Max noise is 250k. Downstream AIDA appears to be seeing additional noise since S100. 11:21 Returning after an hour the noise has increased significantly in many channels. Scale changed to 10000 in histograms, it appears that the problem is from a couple hot channels. 11:41 'Power' cycled AIDA turned off. bPlast turned on, on its own, then BB7. bPlast doesn't seem to notice anything. 12:21 bPlast and BB7 on. AIDA ON. Rates and histograms given by attachment 7-8. More FEEs noisy, but same level as 11:21. There appears to be the same noisy channel in all of the FEEs (?) Some grounding not properly accounted for, or a wire touching somewhere (?) 13:55h: AIDA & BB7 on. Rates and histograms given in attachments 9-10. Same level as bplast & AIDA on. Same noisy channels in FEEs. According to Nic, these correspond to the end of the ribbon cables & is normal. 13:59 AIDA, bPlast & BB7 on before lunch. Same levels of noise as in previous combinations (attachments 11-12). So it seems we can run with the three sub-systems biased simultaneously.
