Indus Accelerator Complex consists of a 450 MeV electron storage ring Indus'1 and 550-2500 MeV booster-cum-storage ring Indus-2, which is under commissioning. A common injector system that feeds these rings consists of a 20 MeV microtron & a 450-600 MeV booster synchrotron. Hazardous ionizing radiation is emitted from the accelerators of a facility like Indus. Therefore, it is mandatory to install a Radiation Safety System (RSS) at such a facility. The essential constituents of such a RSS are:·Shielding structure for protecting the personnel from ionising radiation;·Detection and monitoring of the radiation levels inside & outside the shielded area;·Protection system for ensuring that nobody is inside the shielded area when the facility is in operation. The radiation safety system was set-up in stages. The RSS for microtron and booster synchrotron was set-up first followed by that for Indus-1 ring. For Indus-2, it was commissioned in July 2005. These systems were then integrated and have been performing as intended. This paper presents the integrated radiation safety system of Indus Accelerator Complex with emphasis to important features of Indus-2 RSS.

Based on a wire model, analytical formulae are derived to describe the spatial distribution of the magnetic field as determined by the parameters of the undulator including positional and orientational errors. Semi-analytical numerical simulations are performed to estimate the tolerance of the errors required for a satisfactory function of the supramini, including the effects of systematic errors (pitch, yaw and roll errors) and random errors of the wire position. The effects of these errors on the quality of the field are then graphically analyzed to show the RMS spread of the functions.
