Title: Roller Cam Positioners

Technical Report ·
DOI:https://doi.org/10.2172/1000327· OSTI ID:1000327

Roller Cam Positioners could support the LCLS undulator sections allowing micron sized alignment adjustment of each undulator in 5 degrees of freedom. The supports are kinematic with the number of degrees of freedom matched to the number of constraints. Ton loads are supported on simple ball bearings. Motion is intrinsically bounded. Positioning mechanisms are based on pure rolling motion with sub-micron hysteresis and micron resolution. This note describes a general purpose positioning mechanism suitable for undulator support.
