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.
