Generation of Intense Ion Beams at the 13 Mev Level on the Hermes-III Accelerator

The HERMES-III accelerator (18 MV, 700kA, 40 ns) uses Inductive Voltage Adder (IVA) architecture to drive a magnetically insulated transmission line (MITL) with a 34-ohm vacuum impedance. In normal operation, the load is a Bremsstrahlung diode operated in negative polarity, from which an intense ele...

Description
Summary:The HERMES-III accelerator (18 MV, 700kA, 40 ns) uses Inductive Voltage Adder (IVA) architecture to drive a magnetically insulated transmission line (MITL) with a 34-ohm vacuum impedance. In normal operation, the load is a Bremsstrahlung diode operated in negative polarity, from which an intense electron beam can be extracted for gamma generation. The relatively high output voltage makes HERMES attractive as a source for high-energy ions which could be used, among other applications, for generating neutrons from high-cross section metal targets. Such beams of both protons and lithium were previously generated1 at the 16 MV level, but in positive polarity with the induction cavities reversed. To preserve the dominant negative polarity mode, ion beams now must be generated in negative polarity, with the resultant beams propagated inside the MITL.
