Due to a piston-type expander machine of the helium refrigerator with cooling power of 600 W the total consumption of liquid helium by the superconducting magnet system of the KEDR universal electromagnetic detector for general purpose created for experiments with e+e- collider VEPP-4M (BINP, Novosibirsk, Russia) could be decreased by factor of two. For exploiting the expander machine, an electronics controlling its valves and allowing adjust a mode of its work is necessary. Developed system consists of the controller and program for PC interacting with it.

TNK facility (F.V. Lukin Institute, Zelenograd) was designed and manufactured at Budker INP. It includes 80 MeV electron linear accelerator-injector and two electron storage rings: the main ring for energy of 2.5 GeV and booster ring for energy of 450 MeV. The paper presents the functional layout of the linear accelerator. The disk-and-washer 2.8 GHz accelerating structure is described. Results of the accelerator startup is presented. In December 2005, accelerated electron current of ~50 mA with energy of ~50-60 MeV was obtained; the beam was captured into the booster ring.
