Indirect measurement of Hermes III voltage

The peak voltages estimated at the HERMES III diode using the parapotential flow theory, the range of H/sup -/ ions, and the radiation output are 20.5+or-0.4 MV, 18.5+or-0.6 MV, and 18.1+or-0.6 MV, respectively. The values correspond to the mean shot-to-shot variation of about 20 shots. The absolute uncertainty is estimated to be about +or-10% for each of the measurements. Within these uncertainties, the measurements are consistent with each other. Associated measurements of peak voltage along the MITL (magnetically insulated transmission line) support the measured diode voltage and show that HERMES III operates as a balanced system, with each cavity contributing equally to the power pulse at the diode.<>
