Low Eneregy Cooler for NICA Buster | |
|
||
| At report will discussed design low energy cooler for NICA buster gives information about starting production elements of cooler. The cooling and accumulation heavy ions with high charge need at very high vacuum condition at presence intensive ion and electron beams. Early this task was realized in BINP for LEIR cooler for accumulation ions bunch for LHC and this expearency used for new cooler with additional diagnostic tools that was tested at high voltage 2 MeV COSY cooler. | ||

| The 2 MeV electron cooling system for COSY-Julich was proposed to further boost the luminosity in presence of strong heating effects of high-density internal targets. The 2 MeV cooler is also well suited in the start up phase of the High Energy Storage Ring (HESR) at FAIR in Darmstadt. It can be used for beam cooling at injection energy and for testing new features of the high energy electron cooler for HESR. The COSY cooler is designed on the classic scheme of low energy coolers like cooler CSRm, CSRe, LEIR that was produced in BINP before. The electron beam is transported inside the longitudinal magnetic field along whole trajectory from an electron gun to a collector. The 2 MeV electron cooler was installed in the COSY ring in the spring 2013. Electron beam commissioning and first studies using proton and deuteron beams were carried out. Electron cooling of proton beam up to 1662 MeV kinetic energy was demonstrated. Maximum electron beam energy achieved so far amounted to 1.25 MeV. Voltage up to 1.4 MV was demonstrated. The cooler was operated with electron current up to 0.5 A. | ||
