 Mon Feb 22 16:47:28 2016, PJCS, Version 8 in nnaida2 outputting and merging two streams
|
nnaida2 , the bare test FEE64 in T9, is successfully running with two streams connected to nndhcp177 ( a Linux64 computer )
Merge running on nndhcp177 is receiving the streams and merging them.
nnaida2 has a slow pulser , 100Hz , connected to one waveform input. |

|
nnaida2 running Version 8 Firmware and data acquisition software outputting both and ASIC data stream and a Waveform data stream to the Merge process.
Merged data is written to file ... attached.
The waveform is running at 100Hz and ASIC data is running at 10Hz. |

Wed Feb 24 15:46:11 2016, PJCS, OR64 - OR of all the ASIC discriminator channels after application of a mask
|
Firmware version8 number 8 has an OR64 added which can be routed, using the Local control, to the Trigger output and hence seen at the front panel Fast
NIM LEMO00 connector.
The OR64 is the OR of all the ASIC Discriminators. Each rising edge of a discriminator signal will give a 10ns pulse on the Fast NIM signal. If |

My GREAT data analyser program reports that the 'fail' bit is set ?

The Fail bit is used to indicate The Timing Vernier word.
I'll post a seperate Elog entry to explain the format.

|
During 'SETUP' the ASIC readout clock ( 500KHz ) is synchronised to the SYNC pulse in V8.10 and later versions of the VHDL.
Attached is a short run for verification.

Thu Apr 14 13:56:17 2016, PJCS, Updating the FEE64 firmware.
|
To update the FEE64 firmware:-
Power-up the FEE64 modules that you wish to update.
Identify the file to be used ( FEE_GF_Feb16_15.bin at 14/4/2016
)
This file should be in the Server ( e.g. aidas1 ) at /MIDAS/Aida.
Edit the file /MIDAS/Aida/FlashPgm.csh and change the file |

Wed Apr 12 12:32:13 2023, PJCS, ASIC power short problem
|
I have taken videos with an Infrared camera of the power being supplied to one isolated ASIC on a mezzanine.
The power supply is a bench supply with current limit set to 3A.
The centre of the ASIC glowed white hot for a short time and then the whole ASIC shows as hot. Ths the short is on the ASIC and not the bond |

02:02 Recovered DAQ from crash. Merger became clogged and the system required a full restart. Raspberry pi also
required a restart to regain control of the USB power relay.

|
Used a program to sort through the settings files located in /MIDAS/DB/EXPERIMENTS/AIDA/Settings_FIle_Name/nnaider1,2,3... and /MIDAS/DB/EXPERIMENTS/AIDA/Options.
By comparing the parameter values we got from this to the value we know they should be set to we found some discrepancies in FEEs 1 and 3-8 with values
being set
