We present an overview of design studies and R&D toward NGLS – a Next Generation Light Source initiative at LBNL. The design concept is based on a multi-beamline soft x-ray FEL array powered by a CW superconducting linear accelerator, and operating with a high bunch repetition rate of approximately 1 MHz. The linac design uses TESLA and ILC technology, supplied by an injector based on a CW normal-conducting VHF photocathode electron gun. Electron bunches from the linac are distributed by RF deflecting cavities to the array of independently configurable FEL beamlines with nominal bunch rates of ~100 kHz in each FEL, with uniform pulse spacing, and some FELs capable of operating at the full linac bunch rate. Individual FELs may be configured for different modes of operation, including self-seeded and external-laser-seeded, and each may produce high peak and average brightness x-rays with a flexible pulse format.

The International Muon Ionization Cooling Experiment (MICE) includes two linear accelerator sections with four RF cavities each within a shared vacuum vessel. Ten cavity bodies have been fabricated for MICE including two spares and one was electropolished. A special vacuum vessel was built to house this cavity and form the 201-MHz Single-Cavity Module. The module was assembled, instrumented and tested at Fermilab for installation and operation in the MuCool Test Area.

  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.
