遥控三维调变的核反应靶架装置

A three-dimension movable target holder controlled by a remote console

描述了遥控三维调变的核反应靶架及其控制器的结构与性能。靶架可通过控制器随意调节实验靶的上下位置、靶面方向和靶在垂直于束流方向的水平位置。靶的位移定位误差小于０．３ｍｍ，靶的转动定位误差小于０．２°。探测死区可以用转动靶面方向来避开。靶支撑片上可装配６个实验靶。

The structure and performance of a three-dimension movable target holder used in nuclear reaction experiments are described. A target supporter including six target positions is mounted on the top of a conveyer, the movement of which is controlled by a digital eletrical console. The vertical and horizontal displacements of the supporter as well as its rotation round the beam axis can be realized, with a translation error of less than 0.3mm and a rotation error of less than 0.2°, respectively. A wanted target can be easily chosen by vertically moving the supporter and the dead detection zone can be avoided by appropriately turning the supporter.
