| | High power conditioning and RF processing of the
input coupler for BEPCII superconductor cavity (SCC)
has been performed. Gas desorption is very important for
a new input coupler; and high power conditioning and
electron bombardment is quite effective for outgasing.
For this reason, the DC bias voltage is applied to the
conductors of coupler in the room temperature
conditioning. RF power with full reflection of 150kW has
been arrived under +(-)2000V DC bias voltage during the
room temperature conditioning. At the same time, other
methods have also been studied to improve the
performance of input coupler during the beam operation.
Up to now, the input coupler works well under the beam
current of 250mA and beam energy is 2.5Gev, which
means the input coupler can feed 100kW RF power to
beam in continuous wave in normal operation. The details
about the high power conditioning and RF processing of
the input coupler will be given in the paper. | |

| | In this article, we'll introduce the RF system of
BEPCII to readers. It consists of 4 subsystems:
superconducting cavity, high power klystron, cryogenic
system and LLRF. The construction of the RF system had
been finished in late 2006. During the last year of running
till now, it has performed very well. | |
