Abstract (en)
[origin: US5857008A] PCT No. PCT/EP96/01145 Sec. 371 Date Jan. 8, 1998 Sec. 102(e) Date Jan. 8, 1998 PCT Filed Mar. 16, 1996 PCT Pub. No. WO96/29723 PCT Pub. Date Sep. 26, 1996In microfocus X-ray equipment for enlarging radiographic short-time recordings, a focussed electron beam for the production of X-radiation (16) impinges on the retarding material of a target (23). In this case, the retarding material in the focal spot (22) passes over into the liquid aggregate state due to the high thermal loading. For this reason, the equipment is operated in pulsed operation, wherein the position of the focal spot (22) on the target (23) is, when each loading occurs, displaced relative to the previous position. The retarding material is arranged in a retarding layer (32) on a carrier layer (33) and the electron beam (16) impinges on the retarding layer (32) oriented perpendicularly to the electron beam (16). A control interrupts the irradiation at the latest when the carrier layer (33) starts to melt.
