Commissioning and Operational Experience of the HLI-RFQ
نویسندگان
چکیده
The high charge state injector (HLI) at the UNILAC provides beams mainly for the super heavy element research (SHIP, TASCA). It comprises an ECR ion source, a radio frequency quadrupole (RFQ), an IH structure and two bunchers [1]. High average beam intensities of rare isotopes are the domain of the HLI. An upgrade program, aimed at increased beam intensity, quality and duty cycle, was started in 2005 [2]. As one part of this, a new RFQ [3] was delivered to GSI in 2009. High power rf commissioning started in November, accompanied by beam emittance measurements of the beam from the ECRIS [4].

COMMISSIONING OF THE 1.4 MeV/u HIGH CURRENT HEAVY ION LINAC AT GSI
The disassembly of the Unilac prestripper linac of the Wideröe type took place at the beginning of 1999. An increase of more than two orders of magnitude in particle number for the most heavy elements in the SIS had to be gained. Since that time the new High Current Injector (HSI) consisting of H-type RFQ and DTLstructures for dual beam operation was installed and successfully commissioned. The...
متن کاملCommissioning of the Triumf Isac Rf System
The ISAC RF system at present consists of a Radio Frequency Quadrupole accelerator, five Drift Tube Linear Accelerators, six bunchers, two choppers and a bunch rotator. The RFQ operates at the fundamental frequency of 35.36 MHz, while the DTLs operate at the third harmonic frequency of 106.08 MHz. The operating power ranges from 45 W to 120 W for the choppers, 1 kW to 20 kW for the DTLs and bun...

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 کاملLinac Commissioning for the Heavy Ion Cancer Therapy Facility HIT
The accelerator part of the clinical facility for cancer therapy HIT using energetic proton and ion beams (C, He and O) has been installed during 2006 at the Radiologische Universitätsklinik in Heidelberg, Germany [1]. The commissioning of the injector linac was performed in three steps for the LEBT, the RFQ and the IH-DTL and has successfully ended in December 2006. Some major results are brie...

At Peking University (PKU) a new helium injector for coupled radio frequency quadrupole(RFQ) and separated function radio frequency quadrupole(SFRFQ) within one cavity, so called as coupled RFQ & SFRFQ, was designed recently[1]. It will provide a 30keV 10mA He beam whose emittance is less than 0.15 π.mm.mrad for the accelerator. It is a combination of a 2.45GHz PKU permanent magnet electron cyc...
