Compact Spectral Characterization of 5-500 MeV X-rays from the Texas Petawatt Laser-Driven Plasma Accelerator

A. Hannasch, L. Lisi, J. Brooks +11

We reconstruct spectra of secondary x-rays generated from a 500 MeV - 2 GeV laser plasma electron accelerator. A compact (7.5 $\times$ 7.5 $\times$ 15 cm), modular x-ray calorimete…
