The electron beam is supplied by a G050400100014 pulsed electron gun at a pulse repetition rate of 50 G050400100015 Hz. The maximum current of the analyzed beam is 4 uA G050400100016 and electron energy resolution is +-28 keV. G050400100017 SAMPLE A 238U target of thickness 200 micro-g/cm2 on an G050400100018 aluminum backing. Amount of electrodeposited 238U G050400100019 target on aluminum was determined by X-ray diffraction G050400100020 method. G050400100021 FACILITY (MICRT,3INDMNG) G050400100022 DETECTOR (TRD) Lexan polycarbonate film as solid state nuclear G050400100023 track detector (SSNTD) placed at different angles G050400100024 with respect to the incident beam direction. After G050400100025 irradiation the Lexan films were cut into equal strips G050400100026 and etched in 6 N NaOH solution for about 1 h to G050400100027 develop the fission tracks. These etched Lexan films G050400100028 were washed, dried and analyzed under optical G050400100029 microscope with a magnification of 400X for the tracks G050400100030 formed during irradiation. G050400100031 METHOD (SITA) G050400100032 PART-DET (FF) G050400100033 ADD-RES Bremsstrahlung yield simulation was carried out using G050400100034 Monte Carlo EGS-4 code. The photon intensity from the G050400100035 Microtron accelerator at a distance of 15 cm from the G050400100036 bremsstrahlung converter (tantalum target) facility G050400100037 was estimated to be 10**10 photons/sec using the code G050400100038 EGS-4. G050400100039 COMMENT By compilers (2013-08-08): Authors also derived G050400100040 fission cross sections for mono-energetic photons by G050400100041 unfolding (photon difference method). However the G050400100042 corresponding figure is not clear from the articles, G050400100043 and they were not compiled G050400100044 HISTORY (20130630C) Compiled by B.L.
