Abstract (en)
An electron accelerator which comprises a target (6 or 206) exposed to the electron beam (e<->) for producing x-ray deceleration radiation and means (106, 108, 110, 112 or 306, 308, 310, 312) for switching the x-ray radiation between a lower first and a higher second photon energy. A first compensating member (14 or 214) which is arranged centrally in the x-ray radiation at a first distance from the target, flattens the radiation intensity distribution when the x-ray radiation is switched to the first photon energy. In the case the x-ray radiation is switched to the second photon energy a second compensating member (80 or 240) which is arranged in the x-ray radiation in a longer second distance from the target in combination with the first compensating member flattens the radiation intensity distribution.
