摘要：
A superconducting quarter-wave resonator with an optimum beam velocity of 0.1c has been developed for the JAERI tandem heavy-ion booster. The resonator structure is made of niobium and copper. A prototype resonator and two resonators for the buncher of the booster have been built. The buncher resonators generated accelerating field gradients of 6 MV/m at an rf loss of about 4 W and 6.8-7.0 MV/m at maximum. The result was confirmed with Cl beams of β (= v/c) = 0.1.
