Millisecond Time Resolution with the Kitt Peak Photon Counting Array
Abstract
The Kitt Peak Photon-Counting Array (KPCA) has been modified to provide access to individual frames, with the accompanying short frame time per exposure of between two and five milliseconds. These changes are described and the instrument's performance is illustrated. Imaging of the Crab pulsar with millisecond time resolution is presented as an astronomical example. Poor observing conditions precluded the photometric quality which would normally be achieved with a photon counter. (SECTION: Instrumentation and Data Analysis)
