Goals • Charge-caching – Integrate into four modulation states at multi k. Hz rate and read out slowly (100 Hz) • Excellent QE, >0. 7 • Buttable for 8 k x 8 k or 12 k x 12 k • Low read noise << sqrt(Full Well/10) September 2009 ATST SWG 8

Goals Requiring Development Buttable Charge Caching e dyn e l Te 4 k x 4 k Sarno QE > 0. 7 ff Low Readnoise

Proposed Sensors • Teledyne – Hybrid CMOS with bump bonded pixels – Visible/IR with and without charge caching – all ATST sensors – IR sensors also have visible response though >1 electron/photon – All cameras for $22 M September 2009 ATST SWG 10

Proposed Sensors • Sarnoff – CMOS – Back side illuminated deep depletion – Extremely low read noise, 2 e– IR Cameras as baseline ~$2. 56 M – Development of visible cameras possibly with Andor ~6 M September 2009 ATST SWG 11
