The Advanced Camera for Surveys (ACS) will be installed in the Hubble Space Telescope during HST servicing mission 3B, currently scheduled for late 2001. ACS has three imaging channels, the Wide Field Camera (WFC), the High Resolution Camera (HRC), and the Solar Blind Camera (SBC). WFC is a high throughput (45% at 700 nm, including the HST OTA), wide field (200"x204"), optical and I-band imager based on a 4kx4k CCD mosaic. The HRC is critically sampled (500 nm), with a 26"x29" field of view, a peak throughput of 25% at 500 nm, and an NUV optimized 1kx1k CCD. The HRC optical path will include a coronagraph which will improve the HST contrast near bright objects by a factor of ~10. The SBC is a far ultraviolet imager, with a throughput of 6% at 121.6 nm, over a 26"x29" field of view and employs a flight spare MAMA detector from the Space Telescope Imaging Spectrograph (STIS) program. We will review the performance of the flight detectors selected for ACS and highlight their contribution to scientific discovery space of ACS. We also discuss the impact of the space environment on ACS and present the results of ground-based radiation testing of the devices.
