Upgrade of existing injectors: the CERN PS?

The possibility of an upgraded performance of the CERN PS that would make it a suitable driver for a first low-intensity neutrino factory was investigated. A closer scrutiny during and immediately after the workshop concluded that the envisaged upgraded performance does not appear rooted solidly in the 40 years of running experience of the CERN PS. In addition, the CERN PS is not expected in the coming years to be available for neutrino-factory operation for more than a small fraction of its time. (9 refs).
