Emission and dose characterization of the 1 kHz repetition rate high-Z metal K α source driven by 20 mJ femtosecond pulses
(2019) In Applied Physics B: Lasers and Optics 125(3).- Abstract
We present the hard X-ray generation of K

for Pt Kα1 and 9 × 10
- 9
for W Kα1. The additional experimental bremsstrahlung-induced dose measurements and modeling were performed. The correspondence between experimental and modeling data for the dose evaluation was found. The dose rate up to 25 μ Sv/h was measured on the top of the X-ray generation chamber.
