Description
The High Intensity heavy-ion Accelerator Facility (HIAF) is under constructed in China. The main feature of HIAF is to provide medium and high energies, high intensity heavy ion beams for nuclear and atomic physics. The Spectrometer Ring (SRing) is the most important experimental terminal of HIAF. A 450 keV electron cooler is designed and will be installed to reduce the beam phase volume and improve the beam quality. It consists of a thermionic electron gun, collector, acceleration and deceleration tubes, homogeneous guiding magnetic field, -450 kV high voltage platform, ultra-high vacuum system and so on. The electron beam with the maximum energy of 450 keV and current of 2.0A can be provided to cool heavy ion beams with the energy up to 800 MeV/u. In this paper, the status and development of components of the cooler was introduced. The key technical challenges including the homogenous longitudinal magnetic field, the low-ripple high voltage system, the electron gun and the collector were presented. The schedule of the installation and commissioning was also discussed in this paper.
