TD, JB, CC | Continued of 9th of April |
Disconnected test - pulser from aida08. Noise conditions improved slightly, probably less pulser events. (Attachments 1 & 2).
We recabled the dew point sensor and flow sensor for the water supply interlock to the FEE64s. When we tried to power up the interlock box, the PSU (charging block) LED was blinking indicating an internal power instability. We then plugged each of the sensors out and into the interlock box and found that the flow sensor was the source of the power supply issue.
The HDMI cable of aida04 appears to be broken or wobbly, but the signals still look the same after powering up again. The adaptor board was reseated.
Pulser peak of test - remeasured the peak in aida02 1.8.L and found the same result as before with 118 channels FWHM c. 95-100 keV FWHM energy resolution. (Attachment 3)
bPlast booster boards connected caused dramatic increase in the noise observed in AIDA. Grounding still needs to take place.
TO-DO for 10.04 - 11.04:
- aida04 asic #1 investigate noise
- aida14 asic #1 & asic #2 u/s? replace ASIC mezzanine?
- noise optimisation of aida-bplast -- (friday if BB7 also powered).

Philippos and Marc | Connection problem |
At 20:15, We lost connection with AnyDesk.
Liliana restarted Anydesk on the AIDA DAQ PC. All seemed fine on AIDA DAQ but there was a more generic issue on the main DAQ, possibly the timesorter.
Helena restarted all after ~30mn and it's all working again now.

NH | Confusing behaviour of rates |
Testing the behaviour of powering down the fast ADCs in aida01 (the hot FEE)
Set local control 2 to 0xff in aida01
Wait... see temperature drpos by ~3 degrees (PJCS reports much larger drop in T9)
So far so normal
*but*
aida05 rates go very high when this waveform is disabled!!
Set local control to 0x00 again
They drop back...
Recalibrated FADCs and back to normal |

CC, NK | Comparison pulser FWHM with/without HT and detector cables |
This elog is the first reliable. Before, the histograms have not been zero'd
Each test are done and compared for AIDA05.1.8L, compared with the pulser (caracteristics, see attachment1)
Test 1: with HT cables shielded
Attachment 2: HT = 100V; cable AIDA05 connected --> FWHM = 77 channels (= 51.3 keV) with a top of the curve at 100 cts (AIDA9.1.8L has also been checked and was at 89 channels)
Attachment 3: HT = 0V; cable AIDA05 connected --> FWHM = 1757 channels with a top of the curve at 15 cts after almost 40 min because the noise had a baseline of 6500 channels
Attachment 4: HT = 0V; cable AIDA05 disconnected --> FWHM = 16 channels with a top of the curve at 110 cts
Attachment 5: HT = 100V; cable AIDA05 disconnected --> FWHM = 17 channels with a top of the curve at 110 cts
Test 2: with HT cables not shielded
Attachment 6: HT = 0V; cable AIDA05 connected --> FWHM = 1452 channels (968 keV) with a top of the curve at 23 cts after 1:15 hours because the noise had a baseline of 7000 channels
Attachment 7: HT = 100V; cable AIDA05 connected --> FWHM = 73 channels with a top of the curve at 100 cts
Attachment 8: HT = 0V; cable AIDA05 disconnected --> FWHM = 15 channels with a top of the curve at 120 cts
Attachment 9: HT = 100V; cable AIDA05 disconnected --> FWHM = 16 channels with a top of the curve at 125 cts
Conclusion: with shielded or unshielded cables, the noise situation seems to be the same, proving that mot of the noise don't come from the cables
Other thing that have been noticed is that the peak of the pulser is shifted when the cables are connected compared to when they are not connected: connected: peak at around channel 21675; disconnected: peak at around channel 21925 |

CC, NK | Comparison of channels in the same FEE64 and ASIC 05.1 and with AIDA13.1.8L |
BB7 is still connected but not biased (same configuration as the previous elog). The channel of the CAEN power supply #0 is connected to ASIC08 and biased at 100V. The channel of the CAEN power supply #1 is disconnected but still biased at 100V. AIDA04 (chained to AIDA05) is biased via a shielded cable to an iseg NHQ 246L power supplied, biased at 101 V with 16 uA.
All the outside drain wires of bplast are now taped to the snout.
Attachment 1: AIDA05.1.8L --> FWHM 60 channels
Attachment 2: AIDA05.1.1L --> FWHM 51 channels
Attachment 3: AIDA05.1.4L --> FWHM 57 channels
Attachment 4: AIDA05.1.12L --> FWHM 65 channels
Attachment 5: AIDA05.1.15L --> FWHM 69 channels
Attachment 6: AIDA13.1.8L --> FWHM 277 channels, chosen because same place than AIDA05 but for the dowstream detector that is still biased with the CAEN module
Attachment 7: AIDA12.1.8L --> FWHM 88 channels, chosen because same place than AIDA05 but of the bottom of upstream detector that is still biased with the iseg module
Attachment 8: AIDA16.1.8L --> FWHM 133 channels, chosen because same place than AIDA05 of the bottom of dowstream detector that is still biased with the CAEN module. This curve has 2 humps |

HT of upstream AIDA from iseg, HT cable shielded, 100V, 17 uA. HT of downstream AIDA from CAEN, AIDA#0. Both channel 0 and 1 of CAEN are on, even though there is just one channel connected. DEGAS platform closed. The crates of BB7 and bplast have been put to the ground of the AIDA's structure (cupper sheet)

The cables of BB7 right between the snout and the preamps are shielded.
AIDA05.1.8L --> FWHM 76-80 channels
Attachment 2: TEST2: BB7 fully disconnected
AIDA05.1.8L --> FWHM 71 channels
Attachment 3: TEST3: BB7 fully disconnected, TAMEX crate unbiased, BB7 NIM crate turned off

There is a new operation available in the System Functions menu in the System Wide Checks page. ( The page needs to be reset once when the FEEs are powered before this function will appear )
Check the Options files are all the same size
Using this function will provide a list of the file sizes of the Options/< fee name >/CONTENTS files along with the last time they were accessed as a list.
It's up to the user, at present, to interpret the results but more is possible if required .... |

TapeServer looks happy, 25 MB/s
Paddy was asking us to give a rough estimate for the number of implants per spill.
I zoomed in on the rates histogram (attachment #2) and it looks like roughly 5 implants per channel in SSD 1 and SSD2.
So this is 5*128*2=1280. Note that I don't know the rate window size (e.g., 1 second, 1 spill?) Probably the window does not catch a full spill.
This might be an over-estimate because an implant in SSD2 may leave a signal in SSD1.
Paddy was getting around 1k or 2k fragments per spill, but to first order it seems consistent.
18:36
Near R9_372 they slightly opened some FRS slits, as there is a belief we may be blocking some of 94Pd.
Implant rate seems similar to before, see attachment #5
Biases did not change more than normal, see attachment #6

A background run has been started to check the AIDA channels.
It is in /TapeData/BGFEB21
Due to some noisy channels the data rate is high (1.5 MB/s) even at 0x64
S4 access will be limited.
I do not know when open if it is worth looking at changing the adapter PCBs of it is more likely DSSD internal. |
