| | The RF Superconductivity was first explored in China
by Dr. Ding Yu of IHEP in early 1970's. Unfortunately
the research was stopped for about 10 years after Dr. Ding
passed away, until the first SRF laboratory was founded
at Peking University by the end of 1980's. The early
efforts of PKU SRF group on the design and fabrication
of L-band high beta cavities using China-made niobium
sheets as well as on developing Nb-Cu sputtering
technology to construct SRF QWR as a post Tandem
accelerator are described. The "SRF accelerator based
FEL light source" project, which was proposed by PKU
SRF group and joined by IHEP & SIAP, was formally
approved by MOST in 2003 as a national key project of
basic research. A series of work around the project carried
out at PKU, including the construction and feasibility test
of the DC-SC photo-injector, the R&D of multi-cell Nb
cavities and cavities of large grain Nb are presented.
Progresses of IHEP SRF group in developing SRF
infrastructures and two 500Hz single-cell cavities for
BEPCII as well as studies on 1.3 GHz & 700 MHz single
cell cavities for proton acceleration are reported. Efforts
made at CIAE on fabricating low beta Nb-Cu SRF QWR
for heavy ion post acceleration and R&D activities in
developing SRF technology for SSRF at SIAP are also
presented. A growing phase of SRF in China is emerging. | |

| | The 9-cell superconducting accelerator module of
Peking University (PKU) is in the end of factory check
and will be constructed very soon. It will be the first
home-made 9-cell superconducting accelerator module at
Peking University and in China. As the main part of the
PKU ERL and FEL project, it is composed of one 9-cell
superconducting cavity, liquid helium tank, liquid
nitrogen tank, tuning system, power coupler, suspending
device, magnetic shielding, measurement and control
device. This paper will give a brief description of the 9-
cell accelerator module. | |
