用于光束诊断的振弦

Vibrating wires for beam diagnostics

S. G. Arutunian, M. R. Mailian, Kay Wittenburg

摘要:

提出了一种新的导线扫描技术。该方法的新颖之处在于,线加热量被用作关于相互作用粒子的数量的信息源。为了提高测量的准确性和灵敏度,焊丝加热测量被再生为焊丝固有振荡频率的变化。通过将导线端部刚性固定在基座上,频率对温度和碰撞粒子的相应通量具有前所未有的灵敏度。所用频率的范围(几十kHz)和传热过程的速度限制了所提出的扫描方法的速度特性,然而,高灵敏度使其成为研究束晕和弱束扫描的有前景的方法。传统的束流剖面监测器通常集中在束核心和松散的灵敏度在晕区,其中大的动态范围的检测是必要的。振弦扫描也可成功地用于中子和光子束的剖面测量和探测。

英文摘要:

A new approach to the technique of scanning by wires is developed. Novelty of the method is that the wire heating quantity is used as a source of information about the number of interacting particles. To increase the accuracy and sensitivity of measurements the wire heating measurement is regenerated as a change of wire natural oscillations frequency. By the rigid fixing of the wire ends on the base an unprecedented sensitivity of the frequency to the temperature and to the corresponding flux of colliding particles. The range of used frequencies (tens of kHz) and speed of processes of heat transfer limit the speed characteristics of proposed scanning method, however, the high sensitivity make it a perspective one for investigation of beam halo and weak beam scanning. Traditional beam profile monitors generally focus on the beam core and loose sensitivity in the halo region where a large dynamic range of detection is necessary. The scanning by a vibrating wire can be also successfully used in profiling and detecting of neutron and photon beams.
