Abstract
For high-intensity heavy-ion beams a non-destructive method of determi ning the incoherent tune shift due to space charge and thus the emitta nce is of practical interest. We have implemented in the SIS a method which was for the first time studied recently at LEAR [M. Chanel, Proc . European Particle Accel. Conf., Sitges, 1996, p. 1015]. In this meth od the coherent space-charge tune shift of quadrupolar beam-envelope o scillations is used to determine the incoherent tune shift. These freq uencies are slightly shifted from 2Q(h,v) due to space charge. The tec hnique and the results of these measurements will be discussed in this paper. (C) 1998 Elsevier Science B.V.
