	The problems of development of high energy electron coolers are discussed on the basis of the existing experience. Necessities of electron cooling application to NICA collider are considered and the project parameters of the electron cooler at NICA collider are presented. Electron cooler of the NICA Collider is under design and development of its elements at JINR. It will provide the formation of an intense ion beam and maintain it in the electron energy range of 0.5'2.5 MeV. To achieve the required energy of the electrons all the elements of the Cooler are placed in the tanks filled with sulfur hexafluoride (SF6) gas under pressure of 6 atm. For testing the Cooler elements the test bench «Recuperator» is used and upgraded. The results of testing of the prototypes of the Cooler elements and the present stage of the technical design of the Cooler are described in this paper.

TUPF01	Cooling for a High Luminosity 100 TeV Proton Antiproton Collider	antiproton, collider, proton, quadrupole	97

	A 10³⁴ luminosity 100 TeV proton-antiproton collider is explored. The cross section for many high mass states is 10x higher in p-pbar than p-p collisions. Antiquarks for production can come directly from an antiproton rather than indirectly from gluon splitting. The higher cross sections reduce the synchrotron radiation in superconducting magnets and the vacuum system, because lower beam currents can produce the same rare event rates. Events are also more central, allowing a shorter detector with less space between quadrupole triplets and a smaller beta twiss for higher luminosity. To keep up with the antiproton burn rate, a Fermilab-like antiproton source would be adapted to disperse the beam into 12 different momentum channels, using electrostatic septa, to increase antiproton momentum capture 12x. At Fermilab, antiprotons were stochastically cooled in one debuncher and one accumulator ring. Because the stochastic cooling time scales as the number of particles, 12 independent cooling systems would be used, each one with one debuncher/momentum equalizer ring and two accumulator rings. One electron cooling ring would follow the stochastic cooling rings. Finally antiprotons in the collider ring would be recycled during runs without leaving the collider ring, by joining them to new bunches with snap bunch coalescence and longitudinal synchrotron damping.

A 10³⁴ luminosity 100 TeV proton-antiproton collider is explored. The cross section for many high mass states is 10x higher in p-pbar than p-p collisions. Antiquarks for production can come directly from an antiproton rather than indirectly from gluon splitting. The higher cross sections reduce the synchrotron radiation in superconducting magnets and the vacuum system, because lower beam currents can produce the same rare event rates. Events are also more central, allowing a shorter detector with less space between quadrupole triplets and a smaller beta twiss for higher luminosity. To keep up with the antiproton burn rate, a Fermilab-like antiproton source would be adapted to disperse the beam into 12 different momentum channels, using electrostatic septa, to increase antiproton momentum capture 12x. At Fermilab, antiprotons were stochastically cooled in one debuncher and one accumulator ring. Because the stochastic cooling time scales as the number of particles, 12 independent cooling systems would be used, each one with one debuncher/momentum equalizer ring and two accumulator rings. One electron cooling ring would follow the stochastic cooling rings.
