Abstract:

The invention is a device to measure the emittance of a charged particle beam. The device is capable of providing precise time resolution limited only by the chosen detector. The device allows a complete emittance determination as a function of time. The preferred embodiment of the invention comprises a plurality of thin foils 11 which generate an optical transition radiation OTR pattern 13 a lens system 14 to collect the OTR pattern 13 from the said foils 11 an optical mask 16 to allow passage of the OTR pattern 13 and a detector array 17 or similar device placed behind the mask 16 which intercepts, senses and measures the point source OTR pattern 13 for each perforation in the mask.
