Wed Apr 10 12:33:58 2019, NH VP, AIDA Firmware Update
|
All AIDA modules have been updated to a new firmware 0xd330701 which should fix the merger issues.
A new GSI WR timestamp page has been added to MIDAS - the SYNC rollover is suggested to be 0xe for now.
(VP is working on lowering the rate of WR SYNC infowords) |

Thu Apr 4 14:07:45 2019, NH, Pulser Configuration
|
Pulser settings during April run:
Rate 2Hz
Delay 250 NS |
|
Wed Apr 3 15:24:06 2019, CA, TD, report - low inquire save state
|
| On Save/Restore Module Settings Tab - "inquire save state" returns an error. See attachment 1. |
|
Wed Apr 3 13:29:20 2019, CA, CB, TD, report - high DAQ stall
|
aida10 runs very fast for a period, then stops.
Have to restart Merger and TapeServer to get it running again.

Arrived at 09:54 - sequenced all FEE64 on
FEE64 not mounted properly - something happened to network overnight, see attachment 1,2 for AIDA system log

|
MBS is currently configured and accepting data:
x86l-94 : AIDA Foreign data receiver
x86l-4 : DESPEC Time sorter |

16:30 good event statistics ok, with 9,10,11,12 running faster (detector FEE64s) (attachment 1)
FEE temperatures ok (attachment 2)

Fig1: FEE temperatures from 26.03.2019 all OK
AIDA has been on today and merger setting fixed (see previous ELOG entry https://elog.ph.ed.ac.uk/DESPEC/36)
Still diagnosing issues with MBS (figure 2) but local data acquisition should be functional. |

Tue Mar 26 14:58:09 2019, NH, VP, How to reset merger
|
If the merger doesn't show "xfer Links => Merger" at the top, it is probably the merger setting has been corrupted somehow. This is
how to reset it
If you go to the web page from which you started the Merge and TapeServer |
|
Mon Mar 25 14:44:33 2019, NH, Merger issues
|
Plastic electronics have now been installed.
Water is not leaking still.
FEE64s powered on at 15:00 to test MBS connection (fig1: temperatures) |
|
Fri Mar 22 15:44:20 2019, NH, End of 22.03.2019
|
End of the day - Detector unbiased and FEE64s turned off for the weekend as they won't be monitored.
Water will remain on. |
|
Fri Mar 22 14:31:24 2019, NH, A few more setup notes I forgot
|
Extra FEE information:
HV braid (0 V) goes into FEE10 (beam left) with LK1 jumper
HV core (-160 V) goes into FEE09 (top) |
|
Fri Mar 22 13:47:32 2019, NH, Resolution Checks
|
Pulser widths of AIDA modules, resolution is fairly typical. AIDA09 still noisier than other DSSD channels.

Figure 2: Raw waves (AIDA01 did not calibrate, so AIDA02 used instead as "non DSSD module") |

Fri Mar 22 13:32:55 2019, NH, AIDA Startup @ 22.03.2019
|
FEEs have been on this morning, temperatures attached
Leakage current attached
the DSSD is attached to the following AIDA modules: |
|
Thu Mar 21 15:45:48 2019, NH, AS, SA, MP, Snout Mounting & DSSD Bias
|
The AIDA snout (with single DSSD and plastic) has been mounted in S4 cave again. DSSD was connected to the outer 4 FEEs again.
-160 V Bias applied and DSSD holds voltage with leakage current of around 1.3 uA (was dropping as only biased briefly)
Bias off and FEEs offline again now as day nearly done. MBS testing will be performed shortly, as well as resolution checks. |
|
Thu Mar 21 14:10:10 2019, NH, FEE Temperatures
|
All 12 FEEs powered up, and temperatures are OK.
Passed ASIC checks and system wide checks - now checking cabling and to mount snout. |
