| | The R&D of 700MHz and scaled 1.3GHz (beta=0.45)
single cell superconducting cavity for high intensity
proton linac has been done. We have completed the
optimal design of the cavity and fabrication of three
1.3GHz cavities in China. In order to evaluate the
performance of superconducting cavity, the cavity
preparation and test facility has been established in IHEP.
Two radiation shielded test pits have been built. The
larger one, with the size of 1.1m diameter by 6m deep, is
for 700MHz cavity test, and another one is for 1.3GHz
cavity test. 300W solid-state RF power amplifiers,
cryostats and LLRF control are all available. We have
made a collaboration with Prof. K.Saito's group in KEK.
The 1.3GHz cavities have been tested in IHEP and KEK
respectively. The maximum surface field gradient Esp=
42.4MV/m was achieved. | |
