The European Spallation Source will require, by its completion, a pulsed Linac capable of delivering a proton beam with a peak power of 125MW and a pulse width of 2.86ms and a pulse repetition rate of 14Hz. The required klystrons are fed by 33 high power long pulse modulators, each rated for 115kV/100A;3.5ms/14Hz. Due to their high power levels, not only the quality of the pulses delivered is...
The stacked multi-level (SML) klystron modulator topology has been suggested as an alternative to conventional pulse transformer based topologies in an attempt to improve output pulse performance and reduce system size for long pulse applications. In this topology, a power converter chain including a high frequency transformer generates the output pulse in a pulse modulation/demodulation...
The APERIODIC research group at the University of New Mexico has been investigating novel triggering technologies for compact pulsed power. These technologies include the use of advanced magnetics and novel topologies to develop high performance compact solid state electrical trigger systems*. One of the technologies under investigation is the use of advanced magnetic materials as the basis of...
Diversified Technologies, Inc. (DTI) recently delivered an Integrated Klystron Test Stand for klystrons under development at the Naval Research Laboratory (NRL) and Communication and Power Industries, Inc. (CPI). The test stand provides an HV beam and depressed collector power supplies, mod-anode modulator, controls, and circuit/klystron protection. The Integrated Klystron Test Stand...
Applied Physical Electronics, L.C. (APELC) has built a suite of wide band antennas, using a fat dipole geometry with an integrated resonator. Each antenna uniquely radiates a damped sinusoid, resulting in several cycles of energy at the predetermined center frequency, and with a wide band of frequency content. The unique aspect to this technology is the capability of using a single pulsed...
