Dewar #6 Specifications

Uses Hamilton Spectrograph
AMOS

Date installed 2/3/98

Detector Lick3 L4-9-00AR Thin 2048x2048
15 u-meter pixels
Mike Lesser thinned

Amplifier AL

Temperature -120 C.

Gain (e-/DN) AR: 1.4 (2.8 with 2x attenuator)
AL: 1.4 (2.8 with 2x attenuator)

Noise AR: 8.7 e- slow, 10.1 e- fast
AL: 8.4 e- slow, 10.1 e- fast

Dark NonMPP Vv=4, -8v @ -118 C (IO pump on):
16 e-/pixel/hour

Vertical Traps A direction: 15
B direction 9

Full Well Vv=2,-8: MPP: 74.7 Ke- / NonMPP: 67.7 Ke-
Vv=4,-8: MPP: 73.5 Ke- / NonMPP: 88.2 Ke-

Fringing 10% @ 8000A
19.6% @ 9000A
23.7%@10000A

Notes Cosmetically very good.
Replaces cosmetically poor thin CCD formerly in dewar 6.
2X attenuator is installed on video line by default (see "Gain" above).
Surface is slightly concave, deviating from flat by about +/- 12 microns.
OK to use MPP.
26v regular added to Dewar#6 box for Vdd and Vr, Feb.18,1997.
