Abstract
We present a new approach to bolometry based on the measurement of the optical reflectivity change of a thin metal layer deposited on a transparent substrate. The reflectivity change of the metal layer results from the temperature rise due to absorption of energetic particles or X-rays. With this spectrally broadband and fast technique measurements of absolute energy fluxes are possible. Contact-less sensing makes this method well suited for measurements in an environment with a strong electro-magnetic noise.
The technique was applied to characterize a newly developed method for the generation of electron beams in dense gases. A very high efficiency for the e-beam generation, approaching 100%, was measured for the first time.
