A computer-automated ion channeling system has been developed to provide an expanded capability on the RBS beam leg of the University's 3 MV Dynamitron accelerator. The basic system components are a PC/AT microcomputer equipped with a multichannel an

A neutron transmission spectrometer has been used to determine the presence of contraband substances in sealed containers. A pulsed 'white' neutron source was created by allowing a pulsed beam of 5 MeV deuterons to impinge on a thick beryllium target

A high speed data acquisition system has been assembled for the identification of contraband in sealed containers. Number densities through a sample can be determined by measuring the neutron attenuation as a function of energy using pulsed beam time

Open-geometry neutron attenuation experiments, by definition, subtend large solid angles. This poses a significant background threat to time-of-flight (TOF) attenuation spectra. Tailoring a laboratory to be suitable for open-geometry experiments, whi

Fast deuterium (D+) and tritium (T+) ion beam pulses are needed in some neutron-based imaging systems. A compact, integrated fast ion beam extraction and chopping system has been developed and tested at the Lawrence Berkeley National Laboratory for t
