Trying the AIDA format power supply with the simple filters installed.
The detector is attached and HV of 200v@3.8uA
Using one channel from each FEE64 as a guide to compare performance. Using the Integrate analysis function Peak width. |

Wed Apr 29 11:34:09 2015, Patrick Coleman-Smith, Fast Trigger timings against Pulser Input and LEC/MEC Fast Comparator threshold setting
|
I have tried the latest version ( 26 ) of the FEE64 code and carried out some measurements of the Fast Trigger delay from the Pulser signal ( not the
Pulser Trigger out ) and observed the following.
The pulser gives a centroid of 28217 in the histogram. |

Wed Apr 29 10:01:27 2015, Patrick Coleman-Smith, Fast Trigger output fault in FEE64 FPGA logic
|
The Fast Trigger output of the FEE64 is formed from the OR of the four OR16 signals ( one from each of the ASICs.
The logic levels of the OR16 signals are active low in the FPGA and so if the are OR'd together then the output is inactive if any one of the ASICs
is inactive. |

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

The main experiment changed to a carbon reaction target at F8 (similar thickness of CH2 previously used), and retuned the ZDS. First BigRIPS run after
retuning is 40Mg_1093 (at 2:29 am, Nov 30th)
The background at F11 has increased. The neutron backgroun incresead by a factor of ~10. The rates of visual scalers also increased; for example |
