Because of the strong space charge of beams from laser ion source, the beam dynamics design of the RFQ has been carried out with a new code, which can deal with space charge effectively. The design of the RFQ structure is performed with an electromagnetic simulation code and the determination of parameters of the structure has been done to maximize the shunt impedance when the frequency is kept fixed. The influences of dipole mode effect and flatness on beams were also discussed.展开更多

A high energy electron imaging research platform based on a 100 MeV Electron Linac (e-Linac) which was designed for experimental research of HEER has been proposed by Electron Accelerator Group in IMP. This e-Linac has two injection beam lines. One is a thermionic RF gun with Alpha magnet and quadrupole magnets, and the other is a photo-cathode RF gun with emittance compensation solenoid(Fig. 1), and parameters details is shown in Table 1. The experimental terminals of this e-linac have been designed for HEER and the Thick Target X-ray imaging.展开更多
