Description
The efficiency of beam injection can be significantly impacted by unintended phycical aperture limitations. Closed orbit distortion can be used to identify such aperture limitations. In principle, the localization of such limitations can be achieved through the usage of beam position monitors (BPMs). The accuracy of localization in this case is determined by the distance between BPMs, which may not be sufficiently accurate.
This paper introduces a novel approach for localization of aperture limitations, utilizing an array of scintillator-based beam loss monitors (BLMs) distributed along the designated accelerator section. Due to the relative flexibility of moving monitors along an accelerator lattice, high localization accuracy can be achieved. Relative calibration of the monitors is performed using Sr-90 radioactive source. The initial measurement results obtained at the VEPP-4M storage ring are presented.
