	During the last three years ACCEL fabricated all 109 superconducting cavities for the Spallation Neutron Source (SNS) in Oakridge, Tennessee. Two series of 35 medium beta (β=0.61) and 74 high beta (β=0.81) cavities have been delivered. Besides cavity manufacturing ACCEL also performed rf tuning and chemical surface preparation. We give an outline on the current manufacturing experience and comment on future developments for industrial cavity production.

THP30	Production of S-band Accelerating Structures	666
	C. Piel, K. Dunkel, H. Vogel, P. vom Stein ACCEL, Bergisch Gladbach
	ACCEL currently produces accelerating structures for several scientific laboratories. Multi-cell cavities at S-band frequencies are required for the projects CLIC-driver-linac, DLS and ASP pre-injector linac and the MAMI-C microtron. Based on those projects differences and similarities in design, production technologies and requirements will be addressed.
