Neutron Time-Of-Flight Based on Fast Chopper at SARAF Proton-Deuteron Accelerator

We describe a facility being developed at SARAF to allow for neutron Time-Of-Flight (TOF) measurements. TOF capabilities at SARAF are due to recent development of a fast chopper system, which makes possible transmission through the RFQ of only a single bunch, which subsequently is accelerated by the superconducting linac, and finally bombards the production target to produce neutron pulse of about 1 nano-second duration. We describe initial development of the TOF system. We also discuss measurements of interest to the nuclear community that can be currently performed at SARAF. Lastly, we emphasize that a fast chopper and TOF system will provide Phase II of SARAF with previously unprecedented capabilities for nuclear measurements. Among the measurements currently planned are: studies of neutron induced fission on actinides, fission fragment yields, and neutron scattering experiments.
