Abstract

The OKA experimental complex to produce a separated Kaon beam from U-70 proton accelerator is under construction at State Research Center IHEP. The Cryogenic and Vacuum System (CVS) to keep the radiofrequency separator at operating temperature of 1.8 K is now at the commissioning stage. Different modes of the CVS operation are investigated to determine the most efficient and reliable one. Measures for reaching of the CVS design parameters and increasing the reliability of its operation are described. The experimental values of heat leaks to the CVS elements are given. The modes of the CVS operation in the emergencies are examined. The technological parameters data acquisition and control system is described.
