Abstract :
The design of the SXLS (Superconducting X-ray Lithography Source) clearing system and its behavior are presented. In normal 200 MeV operation, clearing electrode current is dominated by photoelectrons. Clearing electrodes appear essentially only in several locations but not in the dipoles. The effect of clearing voltage on the tune and the beam profile is also discussed.<>
