Mallorca, 1st of February 2005 Page 2 XMM-Newton Introduction 1) PN specific 2) MOS specific 3) SCOS2000

Mallorca, 1st of February 2005 Page 3 XMM-Newton PN specific – Offset tables No fixed offset tables used for PN. Dump of the offset table inserted before the Start of the Observation: + offset data information always present for an observation - increased overhead: –~7 minutes for FF,Ext.FF, LW –45 seconds for SW, Ti and Burst Repetition number changed from 100 to 50 for FF.

Mallorca, 1st of February 2005 Page 4 XMM-Newton PN specific – EPCE unit EPCE experienced an autonomous warm reboot in rev. 841: –Visible through a drop of the currents of the quadrant-dedicated converters in the EPVC –EPCE runs PROM version => reboot autonomous and smooth. No impact on science. –Investigations => same problem in rev. 741 Actions: –NCR#114 raised –Explanation: SEU that stopped the code –Creation of a DP that detects any EPCE reboot(based on the parameter that counts the warm boot)

Mallorca, 1st of February 2005 Page 5 XMM-Newton MOS specific – EMDH K  EMDH K successfully tested in flight and definitely uploaded in rev  EMDH K improvements: – –Ability to upload up to 250 bright pixels instead of 50 with version J+ – –Cover the possible impact of the failure of the CCD extended range temperature sensor

Mallorca, 1st of February 2005 Page 6 XMM-Newton MOS specific – THIN1 filter assessment Low energy patch observed on a bright source Test to check whether this patch is due to a filter degradation (otherwise CCD degradation): –In rev. 900, on 1ES –Filter wheel moved by 20 steps away from the THIN1 position, in the opposite direction to the calibration source. THIN1 filter does not show degradation of its most exposed area.

Mallorca, 1st of February 2005 Page 7 XMM-Newton MOS specific – filter wheel sanity check Routine control of the filters sanity (degradation, micro holes,…)  Diagnostic Reset Per Pixel mode used

Mallorca, 1st of February 2005 Page 8 XMM-Newton SCOS 2000 XMM-Newton shall be operated with SCOS2000 Rev. 940, fully executed via SCOS2000 (TC,TM) –All modes have been planned –TM comparisons with respect to SCOS1, FITS file comparison Next rev. = rev. 954 Expected to switch to SCOS2000 in phase 3 by April 2005 Definite use of SCOS2000 (phase 4) 3 months later (July 2005)
