Rf Tests of an 805 Mhz Pillbox Cavity at Lab G of Fermilab*
We report recent high power RF tests on an 805 MHz RF pillbox cavity with demountable windows for beam apertures at Lab G of Fermilab, a dedicated facility for testing of MUCOOL (muon cooling) components. The cavity is installed inside a superconducting solenoidal magnet. A 12 MW peak RF power klystron is used for the tests. The cavity has been processed both with and without magnetic field. Wi...
متن کاملA 201 Mhz Rf Cavity Design with Non-stressed Pre-curved Be Windows for Muon Cooling Channels*
We present a 201-MHz RF cavity design for muon cooling channels with non-stressed and pre-curved Be foils to terminate the beam apertures. The Be foils are necessary to improve the cavity shunt impedance with large beam apertures needed for accommodating large transverse size muon beams. Be is a low-Z material with good electrical and thermal properties. It presents an almost transparent window...
متن کاملActinometric Study of RF Hydrogen Discharge at 13.56 MHz and 27 MHz
Hydrogen radio frequency (RF) discharge was studied by optical emission spectroscopy and actinometry. The main aim of this work was the comparison of RF discharges at 2 frequencies – 13.56 MHz and 27 MHz as sources of atomic hydrogen. The power delivered to discharge was 30 W. The concentration of atomic hydrogen was determined by actinometric method in the 200 – 600 Pa pressure range with 5% a...
متن کاملRhic 28 Mhz Accelerating Cavity System*
The 28 MHz accelerating system consists of a quarter wave cavity driven by an inductively coupled 100kW tetrode amplifer and 1kW solid state driver amplifer. 40dB of rf feedback closed around the cavity and amplifers reduces small perturbations within the loop by a factor of 100, and reduces the time required to shift the phase at transition by a factor of 10, limited by the saturation of the d...
متن کاملDevelopment of High Rf Power Delivery System for 1300 Mhz Superconducting Cavities of Cornell Erl Injector*
Development of a 150 kW CW RF power delivery system for 1300 MHz superconducting cavities is under way at Cornell University in collaboration with MEPhI. The system is based on a twin-coupler consisting of two identical coaxial antenna-type couplers derived from the TTF III input coupler design. Because the average power is much higher than in the TTF III coupler, the required coupling is stron...
