Operations of the Leda Resonantly Coupled Rfq*

چکیده
The LEDA RFQ is a 350-MHz continuous-wave (CW) radio-frequency quadrupole linac. LEDA is the low energy demonstration accelerator, a full power front-end prototype for the accelerator production of tritium (APT) linac. This machine has accelerated a 100-mA CW proton beam from 75 keV to 6.7 MeV. The 8-m-long RFQ accepts a dc, 75keV, ~110-mA H beam from the LEDA injector, bunches the beam, and accelerates it to full energy with ~94% transmission. Output beam power is 670 kW. This RFQ consists of four 2-meter-long RFQs joined with resonant coupling to form an 8-meter-long RFQ. The resonant coupling improves the stability of both the longitudinal and transverse RF-field distribution in this long RFQ.

High 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...

Beam diagnostic instrumentation is being developed for the LEDA, a 6.7-MeV, 100-mA-cw proton accelerator, presently being commissioned at the Los Alamos National Laboratory (LANL). This instrumentation will be the basis for much of the Accelerator Production of Tritium and the Spallation Neutron Source linac. Located in the LEDA injector and the high energy beam transport (HEBT) this initial in...

The Low Energy Demonstration Accelerator (LEDA) being constructed at Los Alamos National Laboratory will serve as the prototype for the low energy section of Acceleration Production of Tritium (APT) accelerator. The APT accelerator requires over 244 RF systems each with a continuous wave output power of 1 MW. The reliability and availability of these RF systems is critical to the successful ope...
متن کاملDetermining Phase-Space Properties of the LEDA RFQ Output Beam*
Quadrupole scans were used to characterize the LEDA RFQ beam. Experimental data were fit to computer simulation models for the rms beam size. The codes were found to be inadequate in accurately reproducing details of the wire scanner data. When this discrepancy is resolved, we plan to fit using all the data in wire scanner profiles, not just the rms values, using a 3-D nonlinear code.

The low-energy demonstration accelerator (LEDA) is an operational 6.7-MeV, 100-mA, cw proton accelerator consisting of an injector, radio-frequency quadrupole (RFQ), and all associated integration equipment. Achieving this unprecedented level of performance (670kW of beam power) from an RFQ required a number of design innovations. We highlight a number of those more-significant technical advanc...
