摘 要：In order to perform the studies on a pulsed beam generation system based on a high intensity cyclotron,a test beam line with a pulsed beam generation for a 10 MeV compact cyclotron(CYCIAE-10) has been designed and constructed at China Institute of Atomic Energy(CIAE).A 70 MHz continuous H-beam can be pulsed to the pulse length of less than 10 ns with a repetition rate of 4.4 *** sine waveform with a frequency of 2.2 MHz is adopted for the chopper and a mesh structure with single drift and dual gaps is used for the 70 MHz buncher.A helical resonator is designed and constructed based on simulations and experiments on the RF matching for the chopper.A helical inductance loop that is exceptionally large of its kind and equipped with water cooling for the resonator has been successfully wound and a 500 W solid RF amplifier has been manufactured.A special measuring device has been designed,which can be used to measure both the DC beam and the pulsed *** required pulsed beam was obtained after pulsed beam tuning.
