PRODUCTION OF HIGH DENSITY PROTON CURRENTS FOR COLLIDING BEAM ACCELERATORS AT 15 GeV

A head-on collision of two 15-Bev protons produces an energy in thc center of mass equivalent to about 500 Bev with the target at rest. To achieve significant production of secondaries, intense beams of particles are required,and this is obtained by 'sticking' successive pulses of particles at high energy. Limitations imposed by the accelerating system:are examined, and upper limit; are given to the densities that can be obtained under different assumptions. (auth)
