Description
The concept of a Multi-Frequency Photoinjector (MUFFIN) is aimed the possibility of raising the breakdown threshold due to a reduction of surface exposure time to high fields, and due to the so-called anode-cathode effect. These properties help one to reach the desired beam energies (5-10 MeV) even in a two-frequency half-cell normal conducting cavity. Simulations that invoke standard transverse emittance compensating techniques were made for 1.3 GHz + 2.6 GHz MUFFIN to pro-vide electron bunches with parameters: 0.5-1 nC, 3-20 ps, frpt=1.3 GHz. Results show that one can produce bunches 1) 20 ps, 5 MeV (64 MV/m peak cathode-like surface electric field) with trans-verse emittance 2.5 mradmm consuming only 6.5 MW RF power, or optionally 2) 3 ps, 7.6 MeV (96 MV/m cathode-like field), 3 mradmm, 14.7 MW.
