Progress in Experimental Demonstration of Cooling of Ions by a Bunched Electron Beam | |
|
||
| Electron cooling is essential for achieving high luminosities for hadron colliders by enabling a reduction of emittance of hadron beams in storage rings. For several future projects such as low energy RHIC cooling program (LEReC) at BNL, a low energy electron-ion collider based on HIAF at IMP and a Medium energy Electron-Ion Collider (MEIC) at JLab, since the hadron beam energies are in a range from several GeV to 100 GeV, the required electron energy is up to 55 MeV. Such high energy electron beams can only be provided by a RF/SRF linac. As a result, the electron beam is highly bunched. Cooling of ions by a bunched electron beam has never been realized before, thus it becomes a critical R&D to these projects. Recently we proposed a proof-of-concept experiment to demonstrate cooling by a bunched electron beam utilizing an existing DC cooler at IMP. Here we present a progress report of this experiment. We briefly describe the experiment and show the design parameters. We then report hardware installation and results of the bench tests. We also summarize the results of the cooling simulation studies and discuss the required beam measurement capability. | ||
