  10. Analysis of Irradiation Data Incident on 27.01.19  Some incident happend at 5.8Mrad  Good pedestal at 12:03, bad at 12:13  Same VnSubIn, same Gate-On 21/02/19 DEPFET Lab Meeting 10/18

  11. Analysis of Irradiation Data Incident on 27.01.19  21/02/19 DEPFET Lab Meeting 11/18

  12. Analysis of Irradiation Data Incident on 27.01.19  Pedestals could not be recovered by changing various DCD settings and matrix voltages  Decided to power cycle the module  After the power cycle we saw different switcher and clear voltages:  Clear-on: ~25mA --> ~40mA  Sw-Sub: -10mA --> -23mA  In Addition some gates seem to be „broken“ (see source scans) 21/02/19 DEPFET Lab Meeting 12/18

  13. Analysis of Irradiation Data Source scans  MPV evolution MPV is decreasing (Gate-On adjusted!) CCG at 0V Clear-Off Slowly increasing 21/02/19 DEPFET Lab Meeting 13/18

  14. Analysis of Irradiation Data Source scans  MPV evolution MPV is increasing (Gate-On and ccg adjusted!) Clear-On Jump after power cycle 21/02/19 DEPFET Lab Meeting 14/18
