MOOPMA02	Overview of Regional Infrastructure for SCRF Development	31
	C. Pagani INFN/LASA, Segrate (MI)
	The unanimous ICFA decision to choose the TESLA “cold” technology as the basis for the International Linear Collider, ILC, gave a global impulse to the superconducting RF, SCRF, technology. The perspective of building large accelerators based on high gradient superconducting cavities poses a number of new problems in term of performance reproducibility, large scale manufacturing and cost containment. In parallel with the ongoing R&D on basics in labs and universities, new large regional SCRF infrastructures are being developed to qualify treatment, assembly procedures and ancillary integration in performing cryomodules. US at Fermilab and Asia at KEK are strongly investing in these facilities and also Europe is considering duplicating and adjourning at CERN the operational facility set up at DESY by the TESLA Collaboration. In this paper the ongoing global effort on SCRF through the development of large regional infrastructures is outlined together with their status and plans.

	High Quantum Efficiency Photocathodes are nowadays routinely used as electron sources for laser driven RF guns. In this paper, we review the production, characterization and operation performances of the Cs2Te photocathodes prepared at INFN Milano – LASA and operated at DESY for the FLASH and the PITZ photoinjectors.
WEPMA123	Comparative Analysis of Blade Tuner Optimization Options for the ILC	494
	C. Pagani, N. Panzeri INFN/LASA, Segrate (MI)
	Following the successful experience of the blade tuner concept for superconducting cavities, a full parametric analysis has been performed for ILC cost optimization. Different design details have been reconsidered and optimized on the basis of their impact on the ILC requirements and on production costs. Two different designs have been then developed for two options of fabrication material: titanium or stainless steel. The realization of two prototypes, one for each type, has been recently launched for the designs qualification and comparison. In this paper we discuss the optimization rationales and the expected differences in cost and tuner integration and performances. Cold tests on cavities will be at the basis of the final choice for the ILC.
