Detector History

Test980330 Test performance of CCD10 SITe 2048x2048 after rewiring of focal plane 10 to add SDSU 33ohm heater resistor. After an initial problem with bright pixels caused by cosmic rays from the test lens, CCD10 is working correctly with a gain of 2e/ADU and read noise of 8e.

Test990511 To investigate the following problems reported at SSO

High read noise of 18 e where it used to have 7e
High dark current of 300e at top of image to 200e at bottom in 300 secs exposure
Light leak at 16inch

The measured dark current is very much lower (94e/binnedpixel/1000s) than reported by brian schmidt of 1300e/binnedpixel/1000secs. When the dewar arrived at MSO, there was masking tape on the mounting flange of the dewar. It is a possibility that the masking tape has interfered with the dewar mounting and caused a light leak. The reported noise of 18e is normal for this chip when serial binned 3x3.
