First divertor exposure experiments of a renewable boron pebble aggregate in DIII-D
Erick Martinez-Loran, Angelica Ottaviano, Santhosh T. A. Kumar +21
Boron pebble aggregate was tested for the first time as a high-heat-flux granular plasma-facing material in a tokamak divertor. Exposures of up to $q_{\parallel} = \SI{80}{\MW\per\…
In-orbit Spectral Calibration Prospects for the COSI Space Telescope
Aravind B. Valluvan, Steven E. Boggs, Savitri Gallego +8
The Compton Spectrometer and Imager is an upcoming NASA space telescope in the MeV range. COSI's primary science goals include precisely mapping nuclear line and positron annihilat…
Proton Radiation Damage and Annealing of COSI p-type Cross-strip HPGe Detectors
Sophia E. Haight, Steven E. Boggs, Gabriel Brewster +7
In order to understand the effects of a space radiation environment on cross-strip germanium detectors, we investigated the effects of high-energy proton damage on a COSI detector…
Characterizing hole trap production due to proton irradiation in germanium cross-strip detectors
Sean N. Pike, Steven E. Boggs, Gabriel Brewster +6
We present an investigation into the effects of high-energy proton damage on charge trapping in germanium cross-strip detectors, with the goal of accomplishing three important meas…
