<p>Noticed bursts of high energy noise on aida01 and aida02 during run 47 and 48.</p> <p>Good events rate jumps from 10-20k range to 250k. ADC data items rate jumps from 0-1 to 2k. Data rate being written increases to ~2500 kb/s from ~20 kb/s</p> <p>Effect appears short lived ~30s at a time. On 18/2/22 the asic was check loaded which appeared to remove the increased rate but due to the time taken to asic check the burst had already finished.</p> <p>Asic 2 on aida01 and asic 1 on aida02 are affected. See attached plots.</p> <p>Fast comparator threshold HEC currently set to 0x2 for all</p> <p>Zoomed in region of aida 1 asic 2 and the same region for asic 1 to see the difference are attached.</p> <p> </p>
