Dewar name: #9 Uses: Nickel spectrograph and direct imaging at Nickel. Date: 7/26/93 CCD: Ret #4 Thin 400x1200 4 phases 27 u-meter pixels Amp.: B (turn CCD 180 degree and use DOWN direction) Temperature: -114c. Voltages: Vdd=21.0 Vopg= 2. V2= 2. Vh= 7. V1= 2. Vw= 5. Vt= 2. R=10. VR=13.0 Vsub= 0. -8. -3.5 -8. -5. -8. 0. e-/DN: 1.72 Noise: 3.7x1.72=6.4 e- Note: Keep the dewar cold all the time. UV flood: Do UV flood in dry oxygen with sieve in the dewar. When you do UV flood again, please fill dry oxygen, UV flood for about 40 min, then stop UV flood and pump the dewar for not more than 15 min. and cool it imediatly. (don't expourse to air, otherwise you should bake the sieve at 180 degree for about one hour befor you fill oxygen and Do UV flood) QE:(%) 3200A 36.6 3500A 41.6 4000A 50.0 4500A 55.7 5000A 59.0 6000A 59.5 6500A 60.5 7000A 55.2 8000A 47.7 9000A 31.7 10000A 8.7 Note: Slow down parallel clocks with 0.1uf to reduce dark current.
