  The SESRI (Space Environment Simulation and Research Infrastructure) is the new national research infrastructure under construction at Harbin Institute of Technology (HIT) in China. This infrastructure is specifically built to simulate the space environment on the ground. The SESRI has kinds of accelerators, and the 300MeV proton and heavy ion accelerator is a major radiation source, which will supply 100-300MeV protons and 7-85MeV/u heavy ions for studying the interaction of high energy space particle radiation with material, device, module and life. To meet above requirements, the facility adopts the combination of room temperature ECR (Electron Cyclotron Resonance) ion source, linac injector and synchrotron. The ion source is required to provide all stable nuclide beams from H2+ to Bi. The linac injector supplies 1MeV/u heavy ion beams and 5MeV proton beam by using RFQ (Radio Frequency Quadrupole) and IH-DTL (Interdigital H-mode type Drift Tube Linac) linac structures. The synchrotron accelerates heavy ions up to 85MeV/u and proton beam 300MeV. And the 3rd integer resonance and RF-KO (RF-Knock-Out) method are adopted for slow extraction. The status of 300MeV proton and heavy ion accelerator design and construction works are briefly described below.
