First energy loss measurements of intense pulsed ion beams in matter using a Thomson parabola at NDCX-II

The Neutralized Drift Compression eXperiment (NDCX-II) at Lawrence Berkeley National Laboratory is an induction accelerator designed to deliver intense nano-second pulses of ions, up to several tens of nC/pulse, with ion energies up to 1.2 Me V1. Voltage pulses of different amplitudes and lengths accelerate and rapidly compress the ion bunch. The compression is achieved through an induced head-to-tail velocity tilt, which leads to a pulse length of 2 ns FWHM at the target position. A final solenoid focusses the beam to a minimum spot size of 2 mm FWHM on target.
