| Summary:
The prototype Schwarzschild-Couder Telescope (pSCT) is a candidate for a
medium-sized telescope in the Cherenkov Telescope Array. The pSCT is based on a
novel dual mirror optics design which reduces the plate scale and allows for
the use of silicon photomultipliers as photodetectors.
The prototype pSCT camera currently has only the central sector instrumented
with 25 camera modules (1600 pixels), providing a 2.68$^{circ}$ field of view
(FoV). The camera electronics are based on custom TARGET (TeV array readout
with GSa/s sampling and event trigger) application specific integrated
circuits. Field programmable gate arrays sample incoming signals at a
gigasample per second. A single backplane provides camera-wide triggers. An
upgrade of the pSCT camera is in progress, which will fully populate the focal
plane. This will increase the number of pixels to 11,328, the number of
backplanes to 9, and the FoV to 8.04$^{circ}$. Here we give a detailed
description of the pSCT camera, including the basic concept, mechanical design,
detectors, electronics, current status and first light.
