Progress of the JET ITER-Like High Power Prototype ICRF Antenna project
Abstract
: A High Power Prototype (HPP) of the JET ITER-like Ion Cyclotron Range of Frequencies (ICRF) launcher is now being fabricated at Oak Ridge National Laboratory and Princeton Plasma Physics Laboratory. The HPP consists of one quadrant of the full 7.5 MW JET-EP ICRF antenna. Internal matching capacitors are utilized in a circuit that maintains a voltage standing wave ratio (VSWR) at the input < 1.5 over a factor of ten range in resistive loading. The HPP will be tested in vacuum at full capacitor design voltage (35 kV peak) and current (1.25 kA RMS) for 10s pulses. The status of the HPP fabrication and assembly tasks will be reviewed. In addition, the set of diagnostics for measurement of currents, voltages, input impedance, and temperatures (including in-situ optical measurements of the capacitor braze-joint temperatures), will be discussed. Finally, a detailed description of the test plan for the HPP will be presented.
