THIOA01	Ultimate Performance of Relativistic Electron Cooling at Fermilab	31
	A. V. Shemyakin, L. R. Prost Fermilab, Batavia
	The Fermilab’s Recycler ring employs a 4.3 MeV, 0.1 A DC electron beam to cool antiprotons for accumulation and preparation of bunches for the Tevatron collider. The most important features that distinguish the Recycler cooler from other existing electron coolers are its relativistic energy, a low value of the longitudinal magnetic field in the cooling section, ~100 G, and the lumped focusing in the electron beam lines. The report will summarize the experience of designing, commissioning, and optimizing the performance of this unique machine.

	The electron cooler of a 2 MeV for COSY storage ring FZJ is assembling in BINP. The 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. This optic scheme is stimulated by the wide range of the working energies 0.1(0.025)- 2 MeV. The electrostatic accelerator consists of 34 individual unify section. Each section contains two HV power supply (plus/minus 30 kV) and power supply of the magnetic coils. The electrical power to each section is provided by the cascade transformer. The cascade transformer is the set of the transformer connected in series with isolating winding. This paper describes the status of the electron cooling assembling.
