Popis:	A passive calorimeter for diagnostics of high energy pulsed electron beams is described. It consists of a thin rectangular sheet which is irradiated by the electron beam in a central region. The generated heat diffuses outwardly to the ends so that each position experiences a temperature maximum. Thin strips of materials which melt at various temperatures are coated on the surface to provide a record of the temperature maxima of the calorimeters. The corresponding heat diffusion problem is analyzed and used with the experimental results to calculate the initial temperature of the irradiated region, and thus the dose. The calorimeter absorbs only a small fraction of the beam energy and is therefore useful for making dose measurements simultaneously with experiments.
