q f rc rc q h lbeam Nomenclature: rc radius of curvature K curvature Lbeam actual beam length (microns) lbeam apparent beam length (microns) h tip deflection q angle of beam from horizontal or half cone angle f arc angle of entire beam (1) (3) (2) (4) • Strategy: • use (3) to find rc from h and Lbeam at room temperature • use (4) and lbeam at RT to find q • use (4) and lbeam to solve for rc at other temperatures
