Radiation safety during the commissioning trials of synchrotron radiation beamlines of Indus-2

摘要

There are 26 synchrotron radiation beamlines planned to be installed in Indus-2 for various applications. 5 are commissioned, 2 are under commissioning trial stage and several are under installation. During operation of these beamlines, radiation levels are monitored within and outside hutches. During initial trial runs streaming of radiation to accessible areas through gaps in the hutch structure and overlaps was observed. Shield augmentation and reducing gap between overlaps are found to be effective in preventing streaming of radiation. The paper describes radiation safety features, surveillance program and radiation levels in and around synchrotron radiation beamlines hutches of Indus-2.
