EuroFEL Workshop on Photocathodes and RF Guns

1 Mar 2011, 08:00 → 2 Mar 2011, 18:00 Europe/Rome

Aula "Benvenuti" (INFN/ University of Salento, Lecce (Italy))

Antonella Lorusso (University of Salento, Department of Physics), Giuseppe Penco (Elettra), Siegfried Schreiber (DESY)

Workpackage 3 of the IRUVX-PP project would like to invite you to join our EuroFEL Workshop on Photocathodes for RF guns, organised by Expert Group Injector Commissioning, which will be held at INFN/Physics Department of University of Salento in Lecce (Italy) from 1-2 March 2011.

The following topics will be addressed:

• Photoemission theory (derivation of QE and thermal emittance, cathode engineering)
• Photocathode growth and preparation (metal and semiconducting thin films and metal bulk surface treatments)
• Photoelectrons characterisations (quantum efficiency, thermal emittance, dark current)
• Photocathode lifetime (observations of pollution, RF conditioning influence, UV laser interaction with residual gas, etc.)
• Experience on photocathodes
• Cathode cleaning techniques (laser cleaning, annealing, ozone gas,etc.)
• Advanced photoelectron sources (carbon nanotubes, spindt field emitter, ultracold electron sources)
• New material for photocathodes: high QE, cathodes for IR or green laser light, and for SC guns

The Preliminary Programme is available on the Workshop Website.
