Mini-. beta. insertion and luminosity for the RHIC lattice [electronic resource]
Requirement and implication of the mini-..beta.. insertion, where a pair of common quadrupoles are inserted between the interaction point and the frist beam crossing dipole, in RHIC lattice is studied. For the heavy ion operation, we find that ..beta.. = 1m can be achieved with a +-5m free space for...

| 520 | 3 | |a Requirement and implication of the mini-..beta.. insertion, where a pair of common quadrupoles are inserted between the interaction point and the frist beam crossing dipole, in RHIC lattice is studied. For the heavy ion operation, we find that ..beta.. = 1m can be achieved with a +-5m free space for experimental setup and /cflx /beta// = 500m. The beam size limitation is located at the second beam crossing dipole BC2, where 8cm coil i.d. is considered. When the machine is operating at the proton-heavy ion collision mode, these common quadrupoles should be removed physically in order to let both beams crossing the center line at 3.4 mrad. These mini-..beta.. insertion can increase the luminosity by a factor of 2 ∼ 3. For the proton-proton collision mode, we find that ..beta.. = 0.5m is also operable without the mini-..beta.. quadrupoles due to smaller emittance for the proton beam. The corresponding /cflx /beta// is 2400m. When the mini-..beta.. quads are used, ..beta.. = 0.25m can be achieved. The ultimate luminosity for the proton-proton collision is of the order of 10³³/cm² sec, which may be useful in the quest of the B physics studies. 3 refs., 3 figs., 3 tabs. | |
