Within the framevork of "one-event losses" theory the following formula is obtained for t -pulse radiation response aD) Jr Q rrt ,C p LA cos ix z xexp ( ' c ° ) u I on(t, L / Ucosf) G(#ii: I 0 out oc(OL/Ucsf) RadI at i on from the vacuum s i de ( "di rect" rad i at i on) corresponds z=i and " }( 4. cos I "; radi at i on from the other s i dc (,' ind i rect" rad iat ion) corresponds e arid "ç csa". Q - r'adiatiori pulse energy; m - defines the fraction of photoactive absorption; L - probability of absorption of radiation; p - probability of passing by the electron of the harrier at the vacuum boundar'y; u - photoelectron velocity in the conducting band; P - angle between normal to vacuum boundary and the elect1rori trajectory; K - probability of loss of energy by an electron required for emission per unite of distance; L thickness of photosensitive layer.
