  The design of shield structure for bellow is an im-portant content for the research of beam position monitor (BPM). The bellow shield structure consists of contact fingers and spring fingers. Several alternative schemes for bellow shield were achieved based on BPM detailed structure. The optimal scheme was achieved by the im-pedance simulation analysis with CST. The dimension of the contact finger was decided based on the length of BPM with the stress condition. The C-type string was manufactured and the spring force was measured as well.
