摘要：
Measurement was performed during the initial trial operation of Lithography beam line. (BL-07) of Indus-2 SRS. Transmission of SR through the beam line was optimized by providing bump to electron beam, prior to the measurement. Thin window ion chamber was used for SR measurement in direct beam. Ion current is converted to exposure rate using a calibration factor obtained with respect to Co-60 source. 6 mm thick Cu absorber was used for eliminating SR contribution during BR dose measurement. The exposure rates obtained are 3.83x10(3) Gy/h/mA for SR and 4.2x10(-4) Gy/h/mA for BR. Energy of bremsstrahlung radiation was also experimentally evaluated using attenuation technique. Details of these measurement and results are presented.
