一个名为“质心”的新型质子束位置探测器被放置在 DIRAC 目标站中，并与束流对齐。它的后面是一组用于 DIRAC 实验的各种目标。 “质心”本身收集二次电子，这些电子在被质子束击中时由目标发射[1]。这提供了光束位置的在线验证，而不会通过屏幕阻碍光束路径，并且不会干扰实验。然后，计算机应用程序计算将光束在两个平面上居中所需的校正作为时间的函数。本文将解释这是如何完成的。
A new proton beam position detector named ‘Centroid’ is placed in the DIRAC target station and is aligned with respect to the beam. Behind it there is a set of various targets used for the DIRAC experiment. The ‘Centroid’ itself collects the secondary electrons, which are emitted by the target when hit by the proton beam [1]. This provides an on-line verification of the beam position without obstructing the beam path by a screen, and without perturbing the experiment. A computer application then calculates the corrections needed to centre the beam in both planes as a function of time. This paper will explain how this is done.
