A new facility for providing intense, short ion pulses has become available at the Lawrence Berkeley National Laboratory. The novel induction accelerator can deliver a few nanosecond long pulses of 1.2 MeV light ions such as helium, deuterium and protons. For helium ion beams focused into a 2 mm FWHM diameter spot, a charge per pulse of 20 nC corresponds to an ion fluence per pulse of 3 .1012 ionscm2 and a dose per pulse to the target on the order of 1MGySi. The short pulse length and the very high ion fluence could provide new opportunities such as the observation of the time-resolved multi-scale dynamics of radiation-induced effects. High 1 MeV neutron energy equivalent damage to silicon rates corresponding to 1015 neutronscm2ns may enable the characterization of transient radiation effects and nuclear survivability testing of electronics components.
