Abstract：
The design of the BFEL optical cavity's 5-D precise remote-control adjuster is described. This paper discusses the special chracteristic of the FEL cavity,and introduces how to inplement the transfer of the cavity's displacement and angle adjusting inside and outside the vacuum chamber. This optical cavity adjuster is designed with 3 level control precision,its displacement's adjustment range is ±5mm, the resolution is 2μm,the angle's adjustment range is ±3° and the resolution is 0.5″. This control system has been used in BFEL's experiments.
