Performance of the ECR ion source of CERN's heavy ion injector

In fall 1994 the new heavy ion injector at CERN was brought into operation successfully and a lead beam of 2.9´107 ions per pulse was accelerated in the SPS up to an energy of 157 GeV/u. The ion source, which was supplied by GANIL (France) was in operation almost continuously over a period of about one year and proved to be very reliable. It pro-duces a current of more than 100 µA of Pb27+ (after the first spectrometer) during the afterglow of the pulsed discharge. The current stays within 5% of the maximum value for a time of about 1 ms, which is more than required by the accel-erators. Measurements of the charge state distribution, emittance and energy spread, which were made during this window, are presented together with other operating data

The politics of performance: transnationalism and its limits in former Yugoslav popular music, 1999–2004

This paper examines transnational relations between the Yugoslav successor states from the point of view of popular music, and demonstrates how transnational musical figures (such as Djordje Balaševi?, Mom?ilo Bajagi?-Bajaga and Ceca Ražnatovi?) are interpreted as symbolic reference points in national ethnopolitical discourse in the process of identity construction. Another symbolic function is served by Serbian turbofolk artists, who in Croatia serve as a cultural resource to distance oneself from a musical genre associated by many urban Croats with the ruralization (and Herzegovinization) of Croatian city space. In addition, value judgements associated with both Serbian and Croatian newly composed folk music provide an insight into the transnational negotiation of conflicting identities in the ex-Yugoslav context. Ultimately the paper shows how the ethnonational boundaries established by nationalizing ideologies created separate cultural spaces which themselves have been transnationalized after Yugoslavia's disintegration
