Description

Bendable metal mirrors have been implemented in two SGM undulator beamlines at the ALS. A piezo-electric actuator is employed to deform the mirror to image the SGM exit slit which moves longitudinally in the beamline as the grating rotates. The design and performance of these mirrors is discussed. Computed deformations and slope errors are compared to those found during optical metrology. The soft x-ray spot size produced at the experiment is shown
