WEPMA26 | Multipacting Study for the RF Test of the MICE 201 MHz RF Cavity at Fermilab MTA | 1037 |

One 201 MHz RF cavity for the Muon Ionization Cooling Experiment (MICE) will be tested at Muon Test Area (MTA) in Fermilab. Before the Coupling Coil is ready, we will use the fringe field of the Lab G magnet to study the cavity performance in external B field, which can significantly change the multipacting situation in cavities. In this report, we present the multipacting study of the MICE 201 MHz cavity with the fringe field of Lab G magnet. We will survey the co-axial waveguide, the cavity body and the loop coupler region at different power levels and different fringe field magnitudes. | ||
