The superconducting cavities for the Tritron

The Tritron is a separated orbit-cyclotron with superconducting magnets and RF-cavities. The six cavities operate at 170 MHz. They are fabricated by electroplating copper onto fiberglass shells. The copper is electroplated with PbSn as superconductor. Test results are given. The accelerating voltage and the quality factor Q lie above the design values. The highest gap field reached was 10.6 MV/m.<
