摘要
X-ray spectroscopy is a valuable tool for diagnosing laser-imploded capsules. Using a compact spectrometer/streak camera, which fits down a 6-in.-diam tube, we routinely perform time-resolved measurements of deuterium-filled capsules, seeded with Ar, on implosions driven by the NOVA laser. Future high performance targets will preclude the use of Ar as a diagnostic; we are pursuing spectral diagnostics at higher proton energy (Ne-like Xe) and have performed a series of direct drive implosions of capsules filled with Xe, and with Kr, to help validate line broadening models for Ne-like ions. We will discuss the details of the instrument and these experiments.
