	Curved crystals have been successfully used for a long time on the proton synchrotron U-70 of IHEP for the extraction of high-energy proton beams. With the beginning of the program for accelerating carbon ions at the U-70, crystalline deflectors of different lengths and different bending angles have also found application to provide experimental physical installations with ion beams. The report overviews recent results of activity in implementing crystal deflectors to extract proton and ion beams for the fixed-target experiments at the U-70 synchrotron of IHEP of National Research Centre "Kurchatov Institute".

THPSC24	Fast Wire Scanners for U-70 Accelerator of IHEP	459
	V.T. Baranov, V.N. Gorlov, D.A. Savin, V. Terekhov IHEP, Moscow Region, Russia
	The fast wire scanners are used for the transverse beam profile measurement in horizontal and vertical planes at the IHEP U-70 Accelerator. They cover the total range of operating beam intensities and energies of the circulating of proton and ion beams. The scheme of the scanners is based on a rotary brushless servomotor produced by the "Faulhaber" company. The speed of the fork with the carbon fiber is 16 m/s. The rotation mechanism and the control electronics was done to take into account the available radiation levels at the locations of the wire scanners. This report gives the mechatronic design of the wire scanners and provides a system overview.

	Updated beam monitor system executes continuous monitoring surveillance beam losses around the IHEP UÂ70 accelerator. The system consists of 120 detectors. One is located upstream of each bending magnet in the median plane outside of the beam-pipe at 60 cm apart. The detectors are cheap ion chambers filled with air under barometric pressure and 1.8 liter volume. Chamber signals processing is based on digital integration and done in the framework of the UÂ70 Control System. Acquired data are used to facilitate tuning of the accelerator, minimize beam losses at any point of the machine circumference and consequently decrease damage for accelerator equipment. This report gives a brief description of the system and the result of run experience as an example.
