Infrared imaging diagnostic method for two-dimensional calorimetric diagnostics has been developed intense pulsed electron beam (IPEB). By using a 100-μm-thick tungsten film as the infrared heat sink IPEB, emitting uniformity of source can be analyzed to evaluate efficiency and stability diode system. Two-dimensional axisymmetric finite element transfer simulation, combined with Monte Carlo calculation, was performed error estimation optimization method. The test finished IPEB generated by explosive emission pulse duration (FWHM) 80 ns, energy up 450 keV, total current over 1 kA. results showed that it is possible measure cross-sectional density distribution sensitivity 0.1 J/cm(2) spatial resolution mm. technical details, such irradiation protection bremsstrahlung γ photons functional extensibility were discussed in this work.
