“…Experimental conformation was recently [4] obtained when a 2 MeV proton beam was successfully transmitted through a plasma window with immeasurable energy and/or beam losses. Additionally, that plasma window had a density, which is a factor of 2.7 higher (and a correspondingly higher target thickness) than the proposed plasma window.…”

Proton beam loss between window and the target in the SNS ring to target beam transport can be completely eliminated, if Plasma Windows replace solid vacuum windows.Consequently, all problems associated with proton solid-window interaction will no longer exist. The Plasma Window is a novel apparatus, which utilized a short plasma arc to provide a vacuum-atmosphere interface without any intrusive solid structures.Extrapolating present technology to SNS implementation is a straightforward engineering issue. Among the many advantages that this technology offers are: elimination of a 4% proton beam loss, water removal from vacuum interface and elimination of radioactive water problems, as well as power and vacuum equipment savings.

Advances in neutron science have gone hand in hand with the development and of particle accelerators from the beginning of both fields of study. Early accelerator systems were developed simply to produce neutrons, allowing scientists to study their properties and how neutrons interact in matter, but people quickly realized that more tangible uses existed too. Today the diversity of applications for industrial accelerator-based neutron sources is high and so to is the actual number of instruments in daily use is high, and they serve important roles in the fields where they're used. This chapter presents a technical introduction to the different ways particle accelerators are used to produce neutrons, an historical overview of the early development of neutron-producing particle accelerators, a description of some current industrial accelerator systems, narratives of the fields where neutron-producing particle accelerators are used today, and comments on future trends in the industrial uses of neutron producing particle accelerators.

“…If the current is low ( 10 A) and the beam spot a diameter of 1 cm, then thin pressure windows can be used. Various approaches have been made to overcome the thermal and mechanical problems of thin windows, generally by the use of windowless targets [7], [8]. We have assumed in our design studies 6 atm-cm of gas at a pressure of 3 atm.…”
