Abstract: This disclosure relates to a proton beam degrader and a cooling assembly. The proton beam degrader includes a degrader foil that is positioned within a path of a particle beam directed to strike a target. The degrader can include a plurality of fins positioned outside of a conduit within which the degrader foil is positioned to transfer heat away from the degrader foil and into a cooling channel formed in conjunction with the cooling assembly. The degrader foil can have chamfered corners to further improve heat transfer. The degrader foil can include at least one aperture to aid in forming a vacuum condition across the degrader foil. In some examples, where a target cannot operate in a vacuum environment, the degrader can include a degrader foil devoid of any apertures.

Abstract: A motion capture system comprising: a master clock configured to repeatedly generate and output, at a frame rate, a primary clock signal that conveys when a video frame starts; a first camera configured to capture light within a first set of wavelengths and operably coupled to receive the master clock signal and initiate an image capture sequence on a frame-by-frame basis in fixed phase relationship with the primary clock signal to generate a first set of images at the frame rate from light captured within the first set of wavelengths; a synchronization module operably coupled to receive the master clock signal from the master clock and configured to generate a synchronization signal offset in time from and in a fixed relationship with the primary clock signal; and a second camera configured to capture light within a second set of wavelengths, different than the first set of wavelengths, and operably coupled to receive the synchronization signal and initiate an image capture sequence on the frame-by-frame bas
