Detectors have been moved out for safety

Data rate appeared very high c. 2000 kB/s instead of the usual 200 kB/s.

Rate on first two ASICs of aida02 was high (~2 kHz) but rest of aida01-04 looked fine.

ASIC check load reduced rate back to normal levels. Data rate reduced back to 200 kB/sec.

New ADC offsets loaded into the CARME_Sort code

&nbsp;

Aida03 appears to be down. Check load does not resolve issue. Moving detector arm does not resolve issue. No spike in leakage current observed. System checks appear OK.&nbsp; Zeroing ADC data item statistics keeps aida03 at 606023857 items and does not zero.

Issue resolved by resetting the data links for aida03

Waiting for the target.

Beam has been running, we have been running without storage.

See attachment showing beam stripe on the detectors.
