Operation of Hybrid III as a facility magnet

Hybrid III generated fields of 33.6 T in 1991 and 34.2 T in 1992, both in a room-temperature bore of 33 mm. Starting 1993 it has been operated as an FBNML facility magnet, generating either 33 T in a 33-mm bore or 22 T in a 144-mm bore. This paper describes our experience in operating Hybrid III over the past 8 months since December 1992. By the end of 1993, Hybrid III is expected to reach 23 T in the 144-mm bore and, with inserts employing superior alloys, 35 T in the 33-mm bore.<
