EPIC real-time monitoring

B. Altieri EPIC TTD operations meeting # 6 Paris, 7/8 Feb. 2001

EPIC real-time QLA monitoring
· INSCON duties: ­ live QLA exposure accumulation of MOSs & PN ­ print-outs of:
· PN image · MOS image (noise diagnostics diagnose)

­ Count rate plots dropped since new EPIC derived parameters introduced (indicators of soft-protons) ­ Reports in the ODV for every EPIC exposure:
· "performed time" versus "scheduled time" · count rate, CCD noise, and exposure comments (internal web only)

EPIC r/t information: ODV
· ODV : Observation Database Browser (ODV) ­ real-time information is immediately available on the Web:
· http://xmm.vilspa.esa.es/xmmobs/

­ More information available on the internal Web ­ Complete and filled systematically since rev 170. ­ Reduced search capabilities · Information also to be dumped into summary tables: ­ http://xmm.vilspa.esa.es/~xmmdoc/realtime/ ­ but at longer timescales (internal web) · Paper print-outs ­ All EPIC exposures since the start of the mission in the operations room.

EPIC radiation monitoring
· INSCON monitors : ­ the 2 RGS CCD9D above threshold counters ­ PN discarded line counters ­ the 2 MOS CCD2-7 event counters · An alarm of any of the above parameters trigger safing of the MOS's and PN · Very safe and successful approach: reduced MOS CTI slope since last Nov. 2000 flare · Very quite "soft-proton" activity November July.
