Date of Award
Cornell University has designed an Energy Recovery Linac (ERL) X-ray facility, necessitating high-brightness electron beam emittance to be provided by the injector. This has posed a continuing technical challenge in the design and contruction of a DC photoemission gun, which is intended to give 100 mA average beam current in a 1300 MHz CW bunch train (77 pC/bunch), as well as to operate at up to 750 kV cathode potential. Construction experience in light of difficulties in meeting the injector requirements will be described. Additionally, in a separate but related topic of interest, the application of Fowler-Nordheim theory to photoassisted field emission is discussed.
