Scientific paper

In January 2007, the Hubble Space Telescope (HST) Advanced Camera for Surveys (ACS) lost its Wide-Field Channel (WFC) and the High Resolution Channel (HRC) due to a failure in its Low Voltage Power Supply (LVPS). A team was rapidly assembled to determine if the ACS could be repaired as part of HST Servicing Mission 4 (SM4). This team includes contributors from NASA's Goddard Space Flight Center, Ball Aerospace, and Teledyne Imaging Sensors. It determined that all of the capabilities of the ACS could be restored and created a concept for the ACS-Repair (ACS-R) component of SM4. ACS-R will restore the WFC of ACS by replacing the existing CCD Electronics Box (CEB) with the CEB-Replacement (CEB-R) and providing power from a new Low Voltage Power Supply Replacement (LVPS-R). The new LVPS-R will also attempt to restore the HRC function by providing power through the original power bus. In this presentation, we focus on the concept and technical aspects of the ACS-R.
