STRONG FIELD EFFECTS AND THE LUMINOSITY LIFETIME OF A HEAVY-ION COLLIDER

[摘要] The Relativistic Heavy Ion Collider (RHIC) will accelerate fully stripped ions to beam kinetic energies of 250 (Z/A) GeV/u. For the heaviest nuclei, i.e., 179Au79+, 10(9) ions per bunch will circulate in 57 bunches at a kinetic energy of 100 GeV/u. During bunch crossing, the peripheral interactions of the heavy ions generate a sufficiently large electromagnetic field that spontaneous e+, e- pair creations will occur. Up to 10(7) pairs per second are expected at RHIC luminosity values (2 x 10(26) cm-2 s-1). In addition, a produced electron may be captured by a heavy ion, thus strongly effecting the luminosity lifetime of a heavy ion collider.
