摘要
A test beam line for pulsed beam generation for 10 MeV central region model (CRM) of a compact cyclotron is under construction at China Institute of Atomic Energy (CIAE). A 70MHz continuous H- beam with the energy of dosens of keV or a hundred keV will be pulsed to a pulse length of less than 10ns with the repetition rate of 1-8MHz. A 70.487MHz buncher will be used to compress the DC beam into the RF phase acceptance of +/- 30 degrees of the CRM cyclotron. The 2.2MHz sine waveform will be used for the chopper. A pulse with the repetition rate of 4.4MHz and pulse length less than 10ns is expected after CRM cyclotron.
