<title>Calibration program for the Advanced X-ray Astrophysics Facility (AXAF) high-resolution camera</title>

Abstract

The High Resolution Camera, or HRC, is a set of microchannel plate based detectors designed to fly aboard the Advanced X-Ray Astrophysics Facility (AXAF), a major NASA space observatory. It will undergo a series of calibration tests before launch in September 1998. The overall calibration is planned in three phases: tests performed before delivery, end-to-end testing at Marshall Space Flight Center, and post launch calibration observations. In this paper, we examine the planned calibration program for the HRC, focusing on laboratory and synchrotron tests to be made before delivery.
