  SOXS is the new spectrograph for the ESO NTT telescope able to cover the
optical and NIR bands thanks to two different arms: the UV-VIS (350-850 nm),
and the NIR (800-2000 nm). In this article, we describe the final design of the
visible camera cryostats, the test facilities for the CCD characterization, and
the first results with the scientific detector. The UV-VIS detector system is
based on a e2v CCD 44-82, a custom detector head coupled with the ESO
Continuous Flowing Cryostat (CFC) cooling system and the New General Detector
Controller (NGC) developed by ESO. The laboratory facility is based on an
optical bench equipped with a Xenon lamp, filter wheels to select the
wavelength, an integrating sphere, and a calibrated diode to measure the flux.
This paper outlines the visible camera cryostat, the test facilities for the
CCD characterization and the first results with the scientific detector in the
laboratory and after the integration to the instrument.
