  High average current electron injectors are desired by high average beam power SRF linacs. With respect to the different linac application, different beam qualities are required. Two kinds of electron gun are planned for future projects at IMP, one is thermionic electron gun dedicated for high average current, and another one is photocathode gun which is for high average current and high beam quality or even with high polarization. Current status and development of the high average current electron source are investigated and summarized. The thermionic gun studies are planned and the feasible types of gun for the future Electron ion collider of China (EicC) project are also proposed. The pre-research scheme of these two kinds of electron guns are schemed, which will be the start of high average current and high-quality electron source development at Institute of modern physics (IMP), Chinese academy of sciences (CAS).
