Abstract:
The process for the irradiation of strand-shaped irradiated material (19; 19a-e) which are cross-linked by radiation, the process comprising the steps of:generating a scanned electron beam (17) from a single electron beam (11) in a scanner (12) by means of a scan device (13); generating a fan-shaped radiation field by means of a temporally-controlled back-and-forth slewing movement over a specific angle range transverse to the longitudinal direction of the irradiated material (19; 19a-e); deflecting the scanned electron beam (17) by a deflection magnet (16, 16â€²) arranged between the scan device (13) and the irradiated material (19; 19a-e) for every scan angle of the fan-shaped radiation field; and impinging the irradiated material (19; 19a-e) with the deflected scanned electron beam (17) from two fixed irradiating directions (R1,R2 ) located at an angle to one another which is other than zero.
