Hyper filter-fluorescer spectrometer for x rays above 120 keV

Description: An apparatus utilizing filter-fluorescer combinations is provided to measure short bursts of high fluence x-rays above 120 keV energy, where there are no practical absorption edges available for conventional filter-fluorescer techniques. The absorption edge of the prefilter is chosen to be less than that of the fluorescer, i.e., E/sub PRF/ < E/sub F/, contrary to the prior art technique E/sub PRF/ > E/sub F/. In this way, the response function is virtually zero between E/sub PRF/ and E/sub F/ a… more

Beam propagation in the frequency-converted subsystems of Nova and Novette

Description: An analysis of beam propagation for the frequency converted Nova/Novette systems is given and self-focusing effects are reviewed. It is shown that the nonlinear growth of beam modulation produced by self-focusing is proportional 1/2 exp B where B is the intensity dependent phase retardation (measured in radians) accumulated by the beam. This exponential growth of beam modulation in the baseline frequency conversion/focusing optical train limits the system performance for short pulse (tau < 2 ns… more
