V. Zubkoª, I. Bogdanov, S. Kozub, V. Sytnik, L. Tkachenko Institute of High Energy Physics, Protvino, Russia Abstract The synchrotron SIS 300, developed for the Facility for Antiproton an Ion Research (FAIR) project at GSI, will use fast-cycling quadrupole magnets with 45-T/m central gradient; 10-T/m/sec ramp rate, 105-mm aperture, 1-m effective length. The coil consists of 1 layer, which is divided by 3 blocks in one octant. Collars are self-supporting mechanical structure. Integral multipoles are suppressed by central field harmonics in one of them and central and edge field multipoles are suppressed independently in the second one. Thermal and mechanical characteristics of the magnet are presented too. Variants of protection system parameters for the SIS 300 quadrupoles are discussed. ª – corresponding author |

Zintchenko Institute of High Energy Physics, Protvino, Russia 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. ª – corresponding author |
