| Abstract: | 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 3.83 103 Gy/h/mA for SR and 4.2 10-4 Gy/h/mA
for BR. Energy of bremsstrahlung radiation was also experimentally evaluated
using attenuation technique. Details of these measurement and results are
presented.
