Some Broken Bonds when removed from freezer

When readout using _runNumberInSequence=66 got a strange pattern and thought this was due to broken bonds. It is infact due to the runNumberInsequence chosen not the broken bonds. CoB1 was then allowed to anneal for 24, 48, and 168 hours to see the differences

Took second scan directly afterwards to see the effects of annealing whilst scanning

Following this annealing it was decided to take the sensor to higher doses and see what happened

Sensor had higher dose to get to 5Mrad before easter
wrongcfg file so mean and noise different so 5 MRad not comparable to 3.5

              5Mrad scan conducted after annealing for 168 hours taking in all pixels
              shows beam spot well

              Noticed that there was much increased threshold for 5Mrad run and found that wrong cfg file used so it cannot be compared to earlier dose data. The annealing studies were however conducted with the same cfg file so annealing study still good

              Following the easter bank holiday the sensor was removed from the freezer and allowed to anneal

              After 6 weeks in the freezer due to traveling etc I know hope to conduct annealing studies on this sensor. How accurate they will be I am unsure but hopefully not much change over the 6 weeks in the freezer

              Easy way to check.. perform a scan and compare to 5Mrad data before doing annealing

              Due to sensor frozen for 6 weeks make a scan to know where to start annealing from
              can be compared with 5Mrad data
              used wrong cfg file so need to always sue this one for annealing

              left a week in freezer before testing
              ground wire left on so results are scrap

              The fractional changes for CoB3 and CoB4 at 1 Mrad seem to be in agreeance. However 1500 krad exposure is scrap for many reasons. Therefore this sensor will now be abandoned
