FIELD: measuring equipment.SUBSTANCE: invention relates to dosimetry and spectrometry of pulsed ionising radiation accelerators, particularly pulsed electron and brake radiations. Foil charged spectrograph consists of package of N metal foils, total thickness of which is selected based on equality of extrapolated mileage of electrons d maximum energy of electrons Ε < 511 keV, wherein foils are arranged parallel to each other in vacuum chamber at pressure of Ρ = 10÷10Pa, each foil is connected to separate container, accumulating charge absorbed by this foil with separate connector for removal of charge characteristics and completely coated with dielectric film with thickness of not more than 2 mcm.EFFECT: simple method of measuring electron distribution based on energy, high measurement accuracy.1 cl, 2 dwg |
