XMM-Newton 1 Michael Smith, ESAC PN Monitoring Mallorca, April 2008
2
XMM-Newton 2 Michael Smith, ESAC PN Hot Pixels Mainly Column 64 Hot Pixels
3
XMM-Newton 3 Michael Smith, ESAC PN Noisy Pixels (I) Modified blanking of Column 64 segments in latest BPT updates.
4
XMM-Newton 4 Michael Smith, ESAC Counts fraction due to noisy pixels per CCD: CCD 11 column 64 noisy pixel counts fraction reduced in the rev. 1408 BPT. Blanking of a further 8 pixels in the latest BPT (in use from rev. 1530 onwards). CCD 11 PN Noisy Pixels (II)
5
XMM-Newton 5 Michael Smith, ESAC PN Offset Median (I) Increase in offset median: 2 – 5 ADU for Q0 CCDs since ~ Rev 1408 (Perhaps other CCDs also, e.g. CCD5) Coincides with PN BPT implementation (Rev 1408); however, the PN db changes affected the CCD11 BPT only… Similar to onset of the offset median trend seen in Revs 605 – 660
6
XMM-Newton 6 Michael Smith, ESAC PN Offset Median (II) Regarding the Rev 605 – 680 offset median trend: A correlation was found with the respective Quadrant VC Currents (params F1189-92) (discussed at the Saclay 2003 Ops Meeting)… J. Fauste, S. Rives
7
XMM-Newton 7 Michael Smith, ESAC PN Offset Median (III) F1189: Q0 VC Current …however, in the recent trend: NO correlation with VC Current found. G. Buenadicha, P. Calderon
8
XMM-Newton 8 Michael Smith, ESAC PN Offset Median (IV) Perhaps a side-effect of the other database changes, e.g. RGS Single Node Readout? Several analog electronics temperatures investigated, but NO CORRELATION found with PN offset median trend. P. Calderon
9
XMM-Newton 9 Michael Smith, ESAC PN Offset Variance Change in hot pixel offsets due to the rev. 1490 temperature excursion
10
XMM-Newton 10 Michael Smith, ESAC M. Kirsch PN CTI and Gain corrected energies v. revolution: the current long-term CTI parameters are no longer valid; a refined long term CTI is in the process of being released in a new CCF issue. (Result of SAS 7.1 processing). PN Energy Scale (I)
11
XMM-Newton 11 Michael Smith, ESAC M. Kirsch Line width trend is stable ~0.5 ADU/year increase at Mn (Result of SAS 7.1 Processing) PN Energy Scale (II)
12
XMM-Newton 12 Michael Smith, ESAC PN CTI Determination (I) PN CTI determination and monitoring to be taken over from MPE to ESAC. - Determine line positions of first singles versus RAWY - Fit exponential function to determine column CTE
13
XMM-Newton 13 Michael Smith, ESAC PN CTI Determination (II) Preliminary sanity check: Comparison with Konrad Dennerl results. CTI values generally agree within errors. Still very much a work in progress... Relative CTI per CCD (ObsID 0109270501)
14
XMM-Newton 14 Michael Smith, ESAC MOS Monitoring Bad Pixels & Background Mallorca, April 2008
15
XMM-Newton 15 Michael Smith, ESAC MOS Noisy Bad Pixels Still fewer Noisy Pixels than before cooling. However, some are very persistent and have been included in the most recent MOS BPT (in use from rev. 1515 onwards): 5 pixels for MOS1, and 11 for MOS2. This should reduce count rates by 5 - 15% depending on the CCD.

XMM-Newton 21 Michael Smith, ESAC MOS Low Energy Noise Monitoring (MOS2CCD5 Effect)
22
XMM-Newton 22 Michael Smith, ESAC Low Energy Noise (MOS2CCD5-Effect): MOS1 MOS2
23
XMM-Newton 23 Michael Smith, ESAC MOS2CCD5 effect - Due to Charge Injection? RAWY ~40
24
XMM-Newton 24 Michael Smith, ESAC EPIC TTD#19-4: Test with VID increased to 25 V VID=25V VID=20V Improvement or not?
25
XMM-Newton 25 Michael Smith, ESAC EPIC TTD#19-4: Repeated test with VID increased to 25 V VID=20V VID=25V Improvement or not? Don’t know. But it does not solve the problem!!
