slide2
The cryogenic and vacuum system is built to cool by superfluid helium at 1.8 K two niobium cavities of the RF superconducting kaon separator being under construction at IHEP. First commissioning runs were carried out. During the last run both cavities were successfully cooled down to the operating temperature and cryostated for several days. System description, test results and planned improvements are presented.

conclusion
CONCLUSION

The unique cryogenic and vacuum system to cool superconducting devices at 1.8 K by superfluid helium with mass flow rate about 10 g/s is built. For the first time in Russia this system supplied 1000 l of superfluid helium into two cryostats with superconducting deflectors and it allowed RF powering of the particle separator. During the test run different modes of the cryogenic and vacuum system were tested, some problems were revealed and now the ways to solve them are developed.
