- 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

CA, TD, NH | Summary - 29.10-1.11.19 |
3x MSL type BB18(DS)-1000 installed
detector bias -160V, leakage current c. 1uA @ +21 deg C for all 3x DSSSDs
all FEE64 good event rates (slow comparator 0xa, LEC fast comparator 0xff) c. 120k, or less, typically 30-50k, overall merge rate c. 1.6M data item/s
See https://elog.ph.ed.ac.uk/DESPEC/70
Outstanding issues
- occasional loss of bits 48-63 of WR timestamp for aida09 - can be recovered by power cycle - replace HDMI cable?
- aida09 asic 1 not producing ADC or disc data - replace aida09?
ASIC Check works OK
aida09 asic temp c. 30deg C < other asic temps
- evidence of c. 1MHz extrinsic noise for most FEE64s
- acquisition of waveform data not robust - most ASIC channels do not produce data or quickly stop producing data - PJCS to review firmware rev for Jan/Feb 2020
- require spare DSSSDs, FEE64s, HDMI cables etc |

Is the 1MHz noise actually 1.58Mhz? as this is the frequency of observed noise at LYCCA. |

Judge for yourself
https://elog.ph.ed.ac.uk/DESPEC/191031_125102/1350_18W.png
I would estimate c. 2.5 cycles in 2us => c. 1.2MHz … ?
Note that all of the waveforms are shown on an expanded scale c. 7000-9000 of 0-16383
so the amplitude is significantly less than that observed at LYCCA.

CA, TD | Analysis R7_20 (new version of NewMerger with min info code 4 & 5 data items) |
An analysis of file R6_70 can be found at https://elog.ph.ed.ac.uk/DESPEC/177 attachment 19
We observe c. 80M ADC data items per 2Gb file and c. 160M info code 4 & 5 data items.
This am NH switched NewMerger for a new version which minimises the number of info code 4 & 5
data items. The analysis of one of these data files (R7_20) is appended - attachment 1. We
observe c. 2M ADC data items per 2Gb file. The number of info code 4 data items is significantly
reduced as expected but info code 5 data items are not observed.
Info code 4 & 5 data items will increment every (2^28 * 1e-9) 0.268s and (2^48 * 1e-9) 3.26d.
If we examine the verbose output (attachment 2) we observe that each data block only contains
c. 60 ADC data items - a small fraction of the capacity of each data block. |

CA, NH, TD | Friday 29th March 2019 | 16:30 good event statistics ok, with 9,10,11,12 running faster (detector FEE64s) (attachment 1)
FEE temperatures ok (attachment 2)
detector bias/leakage currents ok (attachment 3)
system wide checks ok *except* FEE64 Linux memory information check causes script error,
WR decoder status returns errors
DAQ & Merger running ok

CA, NH, TD | MBS Relay startup | To start the MBS Data Relay, click on the top rightmost of the MIDAS icons (MBS relay, Data Relay => MBS) in
Desktop 3. (attachment 1)
This will bring up the Data Relay MBS terminal.
Ensure the path defined in the datarelaymbs is set to the correct directory (shown in attachment 2) |
