RF fingers in a bellows assembly provide electrical continuity for the image current between adjacent vacuum chambers. They are required to absorb all misalignments between the two chambers while minimizing abrupt changes in the beam aperture. In addition, during bake-outs of the chambers the fingers are required to accommodate their large thermal expansions. The latter is achieved either by having a sliding-contact finger design or a deformable finger design. In this paper we describe a version of the deformable finger design which permits large compression, significant misalignments and axial extension. A novel method of fingers' fabrication, FE analysis and test results are presented.

High performance goals of NSLS-II require stringent mechanical stability of its instruments such as BPMs, slits, mirrors, monochromators, and detectors. Mechanical stability of these components can be compromised by site-wide as well as local vibration sources (pumps, compressors, etc.). Several vibration studies have been performed at NSLS-II at the request of beamline users. This paper presents the results of these studies highlighting sources of vibration and mitigation strategies.
