Talk

The klystron based RF systems for the APS storage ring were recently modified to support the MBA based lattice of APS-U. This involved both the high and low power components of the RF systems. Discussed are the some technical details, challenges faced, and the lessons learnt.

46. Testing and Improvements on the 27 MHz RF System for plasma generation at the Spallation Neutron Source

Talk

The Spallation Neutron Source at Oak Ridge National Laboratory utilizes a dual RF system for H⁻ beam generation, where a continuous wave (CW) 300-450 W 13 MHz RF initiates a low-density plasma that is subsequently enhanced by a pulsed 60 kW 2 MHz RF to achieve high-density plasma. Recently, we have tested a new pulsed 50-150 W 27 MHz RF on the Ion Source Test Stand to replace the CW 13 MHz RF,...

A 2-cell 1.5-GHz SRF cavity was tested in a vertical test Dewar in NSRRC, Taiwan. The Dewar was filled with liquid helium at a temperature of 4.2 K. RF power was feed in throug an probe at the cavity axial center line. The quality factor of this SRF cavity at various field strength was measured. The system setup, probe design, and the measured results are reported in this presentation.
