Antiproton Production and Accumulation for a 20-TeV Anti Pp Collider

摘要

Stochastic cooling is capable of providing a flux of 3.10 exp 8 anti p/second, adequate to fill a 20 TeV collider in 12 hours for operation at luminosity L = 10 exp 32 cm exp -2 s exp -1 . This represents an order of magnitude improvement over the FNAL-source design goal. It is made possible mainly due to higher bandwidth (4 GHz vs 1 GHz) and a lower psi/sub max//psi/sub max/ ratio (350 vs 10 exp 4 ). Systems operating in the 4 to 8 GHz band are necessary, a technology which goes beyond the 2 to 4 GHz systems presently under development, but appears within reach with a moderate R and D effort. Stochastic cooling in the 8 to 16 GHz range holds the promise of small transverse emittance (less than or equal to 1 mu m normalized), allowing even shorter filling times or the use of lower field, larger circumference colliders, should such devices prove more cost-effective.
