  SOXS (Son Of X-Shooter) is a single object spectrograph built by an
international consortium for the ESO NTT telescope. SOXS is based on the
heritage of the X-Shooter at the ESO-VLT with two arms (UV-VIS and NIR) working
in parallel, with a Resolution-Slit product of about 4500, capable of
simultaneously observing over the entire band the complete spectral range from
the U- to the H-band. SOXS will carry out rapid and long-term Target of
Opportunity requests on a variety of astronomical objects. The SOXS vacuum and
cryogenic control system has been designed to evacuate, cool down and maintain
the UV-VIS detector and the entire NIR spectrograph to their operating
temperatures. The design chosen allows the two arms to be operated
independently. This paper describes the final design of the cryo-vacuum control
system, its functionalities and the tests performed in the integration
laboratories.
