RFQ Designed to Accept Beam from a Weak Focusing LEBT

Abstract

Abstract.The LEDA RFQ is a 350-MHz continuous-wave (CW) radio-frequency quadrupole linac. LEDA was designed as the 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, 75-keV, ~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.
