Abstract :
The beam transport system at the National Superconducting Cyclotron Lab (NSCL) consists of 22 cryostats containing superconducting quadrupole doublets or triplets, and 9 superconducting dipoles. The quads achieve gradients of up to 35 T/m in the 10-cm-diameter warm bore. Operating at a maximum current of 20 A allows the helium consumption rate to be kept to less than 0.3 L/h. The dipoles produce fields in the 5-cm gap of over 1.9 T at a current of 100 A, and the two types produce bends of either ±16° or 22.5° at 1.75 T for the 1.6-GeV/c heavy ion beams produced by the K1200 superconducting cyclotron. One year´s operations experience demonstrates their efficiency and reliability
