From annual meeting of the Deutsche Geselischak fuer Biophysik; Juelich, Germany (27 Sep 1973). High-voltage pulses are produced by the discharging of charged condensers in series over a triggered spark gap (voltage doubler according to MARX) and are conducted over a second spark gap on the (tubular anode co-axial surrounding) ring cathode of the x-ray tubes (evacuated to 10/sup - 5/ Torr). At a charging voltage of 150 kV, an energy of 1,125 Joules is stored. The anode surrounding the sample to be irradiated (with a 200- mu tungsten coated aluminium tube) has almost 50% bremsstrahlung transmission. From experiments, no connection could be found between the cathode form and x-ray pulse dose. The half-width of the pulse is on overage 0.2 mu sec, the reproducible dose obtained, 400 R per pulse, the average energy of the x-ray quanta, 44 keV, and the half-width of the axial dose distribution is 45 mm. The apparatus enables the determination of the reaction courses and changes in concentration of radiolytic products in the range of microseconds. (GE)
