We design a C-band deflecting cavity at a resonance frequency of 5712MHz. We study the dynamics of the beams in the cavity to ensure that the cavity is suitable to work as a deflector in the future high-precision bunch length measurement of the electron beam. The deflecting cavity supplied by a RF source of 1MW can generate a deflecting voltage of 1.23MV. We obtain a positive correlation between the phases of the electromagnetic fields and the deflections in y-direction.

Hadron Application and Technology Center (HATC) was founded in Tsinghua University at 2009, its mission is conducting research and development on proton accelerator and its application. The first project is Compact Pulsed Hadron Source (CPHS). It consists of an accelerator front-end'a high-intensity ion source, a 3 MeV radiofrequency quadrupole linac (RFQ), and a 13 MeV drift-tube linac (DTL), a neutron target station'a beryllium target with solid methane and room temperature water moderators/reflector, and tentatively six neutron stations for imaging/radiography, activation analysis, small-angle scattering, reflectometry, beamline optics development, and therapy. Up to now, the 3 MeV linac and target station have been finished. And neutron detecting experiments are underway. At the same time, a 200 MeV proton synchrotron dedicated space irradiation effects research is planed too. The main ring consists of 6 dipoles and 12 quadrupoles. A 7 MeV H⁻ linac is as injector of the synchrotron. The HATC group is developing cooling system for FRIB 80MHz RFQ also.
