Performance of the high gradient, large aperture quadrupoles for the NSCL superconducting spectrometer

Two superconducting quadrupoles, for use as spectrometer elements, have been constructed and mapped. A sextupole, which is within one of the quadrupoles, has been mounted on the helium vessel bore tube. All the elements are assembled into the same cryostat. The mapped results, obtained with a three...

Beschreibung
Zusammenfassung:	Two superconducting quadrupoles, for use as spectrometer elements, have been constructed and mapped. A sextupole, which is within one of the quadrupoles, has been mounted on the helium vessel bore tube. All the elements are assembled into the same cryostat. The mapped results, obtained with a three axis Hall probe, are compared to 3-dimensional calculations over the entire range of operation. Operation experience and heat loads are presented.
