SUPERCONDUCTING PERFORUANCE OF CEBAF/CORNELL PROTOTYPE CAVITIES FABRICATED BY BABCOCK h HILCOX

Babccck & ‘Wilcox (B&W) is participating in the development of an industrial production capability for CEBAF superconducting r‘f accelerator cavities. Fivecell elliptical cavities of the Cornell design (operating frequency 1500 Mhzj have been fabricated at R&W and tested at the Cornell Laboratory of Nuclear Studies (LNS). Performance specifications (accelerating field of 5 MeV/m at a residual quality factor of 3 x
