Detector systems:
Flexure sensor detectors
- First light on first sensor 5/15/03!
Science array CCD/controller performance:
- SITe RN spec: 4.5e- min < 5.2e- typ < 6.5e- max, 20us/px
- Measured single chip RN 3.5e- at 10us/px
- Full array 4.8e- at 10us/px (estimate, not optimized)
- No measurable crosstalk
- CCD operating temperature: -110C
