VIBRATING WIRES FENCE AS A NEGLIGIBLY DESTRUCTIVE BEAM PROFILE AND BEAM POSITION MONITOR

摘要

Vibrating wire can serve as an excellent thermometer of high resolution responding to particles and radiation beams. High resolution of the method is due to the fact, that tht wire oscillations frequency is defined by its tension, which in case of rigid fixation of wire ends has a heightened sensibility to the temperature. Such a wire generator was developed and used for scanning of low-level laser beams. In this paper we suggest to use a fence of vibrating wires. As compared with the traditional way of beam scanning by passive wire and subsequent measurement of secondary radiation/particles the advantage of this method is that the information about the local spatial intensity is concentrated in a specific vibrating wire. The device can be used in vacuum chambers of accelerators as well as for solving of other problems in accelerator tunnel, e.g. for tracing of alignment laser beams.
