First Beam Test of 81.5 Mhz Rfq for Itep-twac
نویسندگان
چکیده
The 4 vane RFQ resonator with magnetic coupling windows as initial part of high-current Heavy Ion Linac for ITEP TWAC facility is presently under commissioning at ITEP. It was constructed for acceleration of ions with 1/3 charge to mass ratio to the energy of 1.57 MeV/u with beam current up to 100 mA. Additional beam dynamics simulations have been carried out for actual fields of the RFQ in order to determine both extreme output beam properties for different ion species with charge to mass ratio in the range of 1-0.25 and limitations for high-brightness of the high-current injector. The beam test of RFQ has been started with protons at relatively low electrode voltage for experimental studying the RFQ beam dynamics in the wide range of rf power operation. First results of the beam test in comparison with beam dynamics simulations are presented.

Simulation of the Accumulation Process in the Itep Twac Storage Ring
Fully stripped heavy ion beam of a nearly relativistic energy and a super high intensity is supposed to be accumulated in the storage ring of ITEP-TWAC Facility that is under construction at ITEP on the base of existing accelerators. Nonliouvillean multiturn injection technique is elaborated to store in the accumulator ring as much as one thousand batches, which are accelerated in the booster s...
متن کاملFirst Tests of the TITAN Digital RFQ Beam Cooler and Buncher
A digital RFQ beam cooler and buncher has been developed as part of the TITAN facility. Following a brief review of the theory of ion motion in such a trap, a description of the RFQ and the experimental setup used for initial testing of the trap is given. Results from the tests are also presented. A square-wave-generator, which uses two stacks of six MOSFETs, has been built. The generator has b...

Linac4 is the near future 160 MeV H- linear accelerator of the CERN presently under construction. It will replace the present Linac2 as injector of the proton accelerator complex in CERN. The Linac4 is composed of a 45 keV ion source, a Low Energy Beam Transport (LEBT), a 352.2 MHz Radio Frequency Quadrupole (RFQ), which accelerates the beam to 3 MeV, and a Medium Energy Beam Transport (MEBT), ...
متن کاملKONUS BEAM DYNAMICS DESIGN OF A 70 mA , 70 MeV PROTON CH - DTL FOR GSI - SIS 12 *
Abstract The future scientific program at GSI needs a dedicated proton injector into the synchrotron SIS, in order to increase the proton intensity of the existing UNILAC/SIS12 combination by a factor of 70, resulting in 7x1012 protons in the synchrotron. A compact and efficient 352 MHz RFQ CH-DTL combination based on novel structure developments for RFQ and DTL was worked out. For DTL's operat...
متن کاملHigh Power Operations of Leda*
The LEDA RFQ, a 350-MHz continuous wave (CW) radio-frequency quadrupole (RFQ), successfully accelerated a 100-mA CW proton beam from 75 keV to 6.7 MeV. We have accumulated 111 hr of beam on time with at least 90 mA of CW output beam current. The 8-mlong RFQ accelerates a dc, 75–keV, ~106-mA H beam from the LEDA injector with ~94% transmission. When operating the RFQ at the RF power level for wh...
