A novel, cost-effective, multi-point Thomson scattering system on the Pegasus Toroidal Experiment (invited)
A novel, cost-effective, multi-point Thomsonscattering system has been designed, implemented, and operated on the Pegasus Toroidal Experiment. Leveraging advances in Nd:YAG lasers, high-efficiency volume phase holographic transmissiongratings, and increased quantum-efficiency Generation 3 image-intensifiedcharge coupled device (ICCD)cameras, the system provides Thomson spectra at eightspatial locations for a single grating/camera pair. The on-board digitization of the ICCDcamera enables easy modular expansion, evidenced by recent extension from 4 to 12 plasma/backgroundspatial location pairs. Stray light is rejected using ...

Mitigation of hard x-ray background in backlit pinhole imagers
Experiments were performed to mitigate thehard x-ray background commonly observed in backlit pinholeimagers. Thematerial of the scaffold holding the primary backlighter foil was varied to reduce the laser-plasma instabilities responsible forhot electrons and resultinghard x-ray background.Radiographic measurements withimage plates showed a factor of>25 decrease inx-rays between 30 and 67 keV when going from a plastic to Al or V scaffold. A potential design using V scaffold offers a signal-to-background ratio of 6:1, a factor of 2 greater than using the bare plastic scaffold. (Source: Review of Scientific Instruments)
