Abstract:

The behavior of the organic crystal diffraction element KAP under intense pulsed x-ray irradiation has been studied using the Lockheed Palo Alto Research Laboratory LPARL high-power Nd-glass pulsed-laser facility. The distortions in spectral data which result from high dose-rate irradiation have been elucidated. The x-ray heating-induced crystal expansion has been observed and shown to imply heating of the crystal to far beyond its normal melting point while maintaining high Bragg reflection efficiency. Streak camera-studies of the phenomena provide further detail and show that the total Bragg reflection efficiency can remain high even for the several ns duration of the x-ray heating pulse.
