ABSTRACT:
An improved particle beam recorder system having a pressure equalizing film gate including a platen for receiving a film thereon in pressure relieved relation to avoid trapping distortion causing air between the film and the platen. The platen can provide a curved film receiving surface and a predetermined tension can be applied to the recording film disposed on the platen to assure positive contact between the film and the platen. A motor driven film advance system is provided to intermittently advance the film through the film gate to thereby intermittently provide fresh and stationary film for exposure and image recording. A particle beam generator is disposed in predetermined relation with the film and the film gate and the recording beam produced thereby is electronically positionally corrected for the known geometric distortions introduced by a predetermined continuous curvature of the film gate and the predetermined tensioning of the film to produce accurate imaging on the film.
