Alpha data used: /May19/{R1,R2,R7,R8,R9,R11} (c. 380 hr.) Absolute calibration calculated with relative calibrated data Data then resorted with absolute and relative gains applied Attachment 1 -> Ey vs Ex plot for all detectors, with slope Ey=Ex show in red. Some non-linearity present, but to first order looks good Attachment 2 -> Alpha peaks pre- absolute calibration in DSSD0 Ex in blue, Ey in red To determine absolute calibration coefficients, assigned leading edge of higher energy peak an energy of 7.4 MeV (Uranium decay series) Divide this by the observed channel number (in keV) to get the absolute gain coefficients in keV/ch for Ex and Ey in each detector. (Note, data already offset corrected, pulser walkthrough) Values typically ~0.72 keV/ch Multiply appropriately by relative gains obtained from gainMatch.cpp to get final gain coefficients. Attachments 3 - 6 -> DSSD0 -> Ex - Ey -> Ey vs Ex -> Ex - Ey vs x strip -> Ex - Ey vs y strip Attachments 7 - 10 -> DSSD1 -> Ex - Ey -> Ey vs Ex -> Ex - Ey vs x strip -> Ex - Ey vs y strip Attachments 11 - 14 -> DSSD2 -> Ex - Ey -> Ey vs Ex -> Ex - Ey vs x strip -> Ex - Ey vs y strip Attachments 15 - 18 -> DSSD3 -> Ex - Ey -> Ey vs Ex -> Ex - Ey vs x strip -> Ex - Ey vs y strip Attachments 19 - 22 -> DSSD4 -> Ex - Ey -> Ey vs Ex -> Ex - Ey vs x strip -> Ex - Ey vs y strip Attachments 23 - 26 -> DSSD5 -> Ex - Ey -> Ey vs Ex -> Ex - Ey vs x strip -> Ex - Ey vs y strip Attachment 27 -> Table comparing sigma and peak centroids of Ex - Ey plots for each DSSD Calculated using simple gaussian fit Encoding: HTML ELCode plain Suppress Email notification
