Description

Camera-based readouts for time projection chambers (TPCs) are an appealing means of measuring low-energy particle tracks, with low cost per channel, high resolution, and isolation of the readout from the gas volume. We have recently developed an optical TPC with an intensified camera-based readout, called CYGNUS-n, as a test platform for rare-event physics TPCs and other TPC measurement applications. The addition of an image intensifier yields excellent signal-to-sensor-noise performance, allowing measurements of low-energy tracks. The fast switching of the intensifier also allows gating on sub-microsecond transient effects that are not possible with typical camera-based readouts, which are limited to millisecond-scale acquisitions. This talk will discuss the development and initial performance tests of CYGNUS-n, along with reconstruction methods developed for processing intensified camera images.
