FORS 1 Blue CCD Upgrade

Linearity, Dark Current, Cosmic Hit Event Rate, CTE

Linearity

The linearity was measured with the ODT testbench using the TDI method at 50 Kps.

Master CCD-X Slave CCD-Y
L Ch. 0 [%] R Ch. 1 [%] L Ch. 2 [%] R Ch. 3 [%]
RMS Peak-to-peak RMS Peak-to-peak RMS Peak-to-peak RMS Peak-to-peak
0.123 0.80 0.1 0.65 0.26 1.54 0.38 2.54



Dark Current

The dark current was measured in the ODT labs.

Master CCD-X Slave CCD-Y
L Ch. 0 [e-/h/pix] R Ch. 1 [e-/h/pix] L Ch. 2 [e-/h/pix] R Ch. 3 [e-/h/pix]

Cosmic Hit Event Rate

The average cosmic rate event rate measured in the Garching lab was   1.48 ± 0.3 events/cm2/min.


Charge Transfer Efficiency (CTE)
