Cryholab, a horizontal cavity test facility: new results and development

In the framework of super conducting RF cavity R&D for high intensity proton LINAC (XADS, EURISOL ...) the IPN Orsay CEA-Saclay collaboration is developing five-cell (700 MHz, β = 0.65) cavity for the high energy section of the LINAC. A first prototype, previously tested in vertical cryostat, has been equipped with a stainless steel 316 L helium vessel and tested in the horizontal facility « CRYHOLAB » at 2K. The cryogenic installation of « CRYHOLAB » is now fully integrated and the cryostat is directly feed from a 120 l/h helium liquefier. After a short overview of the cavity horizontal tests results the cryogenic installation developments and performances will be presented .
