CONSTRUCTION OF A 714-MHz RF SYSTEM FOR THE ATF DAMPING RING
نویسندگان
چکیده
A 714-MHz RF system for the Accelerator Test Facility (ATF) damping ring has been constructed and commissioned. The RF system comprises two higherorder-mode (HOM) damped cavities, a 50-kW klystron, a WR-1150 waveguide network and low-level RF electronics. By using HOM-damped cavities, longitudinal and transverse coupled-bunch instabilities can be avoided even at a maximum beam current of 600mA. A low-level control scheme, which can manage heavy transient beam loading, was designed, and a subset of the system was implemented. We report in this paper the construction and commissioning of this RF system.

Iranian Light Source Facility (ILSF) RF system was conceptually designed based on ILSF requirements for a 3 GeV storage ring and 400 mA beam current at 500 MHz RF frequency. Considering the fact that cavity construction is simpler at 100 MHz and advantages of reducing frequency provided an alternative of 100MHz RF system to be explored for ILSF. After a thorough study on the effect of reducing...

This paper discusses the design, fabrication and testing of a high power alumina disk window in WR1500 waveguide at L Band, suitable for use in the NLC damping ring RF cavities at 714 MHz and the LEDA Accelerator at 700 MHz. The design is based on the fabrication methods used for the successful PEP-II cavity windows. Four prototype windows at 700 MHz have been produced by LBNL for testing at LA...
متن کاملLow-Level RF System Design for the Accelerator Test Facility (ATF) Damping Ring
The ATF damping ring [1] was built to demonstrate the production of low emittance, high current beams for future linear colliders. To attain high beam currents, multiple high current bunch trains are required. The low-level rf system should be designed to minimize both steady-state and transient beam loading effects in the accelerating cavities. In addition the design should be sufficiently fle...
متن کاملTransverse Acceptance Studies at the Atf Damping Ring
The transverse acceptance of the ATF damping ring, estimated from the beam current decay and the timedependent vacuum pressure, is smaller than the design value. We have measured its dependence on sextupole settings, linear coupling, global orbit distortions, local orbit bumps, rf frequency, rf voltage, and on the working point in the tune diagram. We describe the procedure applied to infer the...
