Abstract: During the operation of an electron storage ring where electron beam is stored for the production of synchrotron radiation, probability of accidental beam loss exists. In the present paper, Bremsstrahlung dose due to accidental beam loss in the storage ring Indus-1 has experimentally been measured. Stored electron beam current ranging from ~10 to 100 mA was killed using a beam viewer (destructive) and the Bremsstrahlung dose per event of killing in the forward direction was measured using an ion chamber, made in house, along with an electrometer. Measurement was carried out within the shielded enclosure of the storage ring. Measured dose per event showed linearity up to 99.3 mA. The dose per event of beam killing at 99.3 mA was found to be 5.69 mGy after applying high energy correction factor. The paper describes the experiment and discusses the results.
