Common dispersive-type spectroscopic instruments include prism-type and grating-type, usually using a single dispersive element. The continuous imaging band is always limited by the dispersion angle. When it necessary to image two wavebands with an ultra-spectral resolution that are far apart, difficult due large diffraction To broaden spectral coverage of spectrometer, in this paper, we propos...

The calibration results are presented for a scintillation hodoscopic spectrometer of charged particles, which has been designed an experiment on the search heavy electron bremsstrahlung photon beam at Pakhra accelerator LPI. relative energy and coordinate resolutions E = 40 MeV δ 22% σx 9.5 mm, respectively. It determined that width electromagnetic showers in transverse direction can be describ...
