Abstract: An apparatus and method for a beam target fusion neutron generator comprising a closed cycle flow generator having a continuous liquid phase flowing stream liquid target containing hydrogen isotopes where said stream has a continuously refreshed exposed surface and where said liquid target is high vacuum compatible at cryogenic temperatures; and an ion beam generator adapted to produce an ion beam and focused to direct said beam to bombard said flowing stream liquid target. The flowing stream liquid target can be a thin film curtain and said closed cycle flow generator can be a cryogenic liquid handling system having a heat exchanger adapted to maintain said liquid target at cryogenic temperatures and having a collection reservoir position to capture use target material for recycling.

Abstract: Radiation-hard, steady-state imaging bolometer. A bolometer employing infrared (IR) imaging of a segmented-matrix absorber of plasma radiation in a cooled-pinhole camera geometry is described. The bolometer design parameters are determined by modeling the temperature of the foils from which the absorbing matrix is fabricated by using a two-dimensional time-dependent solution of the heat conduction equation. The resulting design will give a steady-state bolometry capability, with approximately 100 Hz time resolution, while simultaneously providing hundreds of channels of spatial information. No wiring harnesses will be required, as the temperature-rise data will be measured via an IR camera. The resulting spatial data may be used to tomographically investigate the profile of plasmas.
