As one of the main components injector II China ADS LINAC project, an RFQ working at 162.5MHz is used to accelerate proton beams 15mA from 30 keV 2.1 MeV. The four vane has been designed in collaboration with Lawrence Berkeley National Laboratory and built workshop Institute Modern Physics, Chinese Academy Sciences (IMP, CAS). Low power test cavity completed, it shows field flatness within ±1% unloaded Q 12600. RF conditioning results preliminary beam show output energy 2.16 MeV spread 3.5%...
A new special coupler with a kind of bowl-shape ceramic window for proton linear accelerator named as C-ADS at IMP (Institute Modern Physics) has been simulated and constructed beam commissioning through prototype RFQ was done by the end May, 2013. At beginning design in original cavity, 30kW are placed onemeter cavity four-vane structure. In experiments conditioning beam, some problems were promoted gradually such sparking or thermal issues. Finally, two couplers developed fabricated since...
The coupler, which belongs to the field of proton linear accelerator technology, was designed for a four-vane radio frequency quadrupole (RFQ) as high power coupling device. It adopts new bowl-shaped ceramic window structure specially, and its reasonable structural design provides good solution transmission impedance matching. coupler consists inner conductor, outer window, loop complicated water cooling channels. And nitride titanium coating on surface can prevent temperature rising from...
The injector II RFQ accelerator of ADS is used to accelerate protons 10 mA from 35 keV 2.1 MeV. cavity structure the same as that SNS which has a square cross section, and it adopts π-mode rods enhance RF (radio frequency) stability cavity. Low power tests show flatness better than ±0.01 unloaded Q value 13000. CW (continuous wave) working condition was realized after long time conditioning Beam were conducted with current in pulse mode mode, respectively, indicates transmission efficiency...
The next-generation 650 MHz solid state power amplifier designed by the Institute of Modern Physics will utilize 24 modules with an output 60 kW. outputs each 12 be combined using a 12-in-1 rectangular cavity combiner integrated into rack. This combiner, requiring only single stage to combine power, is characterized minimal loss and high combining efficiency. input couplers are adjustable change number combination channels. In event one module failure, corresponding port can adjusted...
A Low Energy intense-highly-charged ion Accelerator Facility (LEAF), which mainly includes an ECR source, LEBT and 81.25 MHz RFQ, was designed to produce accelerate heavy ions, from helium uranium with A/Q between 2 7, the energy of 0.5 MeV/u. The typical beam intensity is up emA CW for beam. facility has been successfully commissioned He⁺ (A/Q=4) N2+ (A/Q=7) beams accelerated in regime Beam properties transmission efficiencies were measured, indicating a good consistency simulated data....
