TUPE31	Manufacturing of Photon Beam-Intercepting Components from CuCrZr	233
	F.A. DePaola, C. Amundsen, S.K. Sharma BNL, Upton, Long Island, New York, USA
	Photon beam-intercepting components in synchrotron light sources have usually been made as water-cooled Glidcop bodies brazed to stainless steel conflate flanges. This fabrication method involves many manufacturing steps which result in increased cost, long procurement time and lower manufacturing reliability. A new design approach was recently proposed which simplifies fabrication by eliminating brazing and utilizes a readily available copper alloy, CuCrZr. This paper describes the manufacturing experience gained at NSLS-II from fabricating many components of this new design. Results of an investigation of various techniques for joining CuCrZr to itself and to SS304 and AL-6061 are also presented.

TUPE33	NSLS-II Beam Aperture Slit Vibration Studies	239
	C.J. Spataro, C. Amundsen, H. Bassan, S.K. Sharma BNL, Upton, Long Island, New York, USA
	Beam aperture slits mounted on stepper-motor driven X-Y stages are used in NSLS-II frontends to define the beam size and to limit thermal loads on downstream optical components. The X-Y stages have positional and resolution requirements of 1 µm and 0.1 µm, respectively. This is achieved by micro-stepping the stepper motor by a Delta-Tau GeoBrick-LV-NSLS-II controller. During the initial operation of the X-Y stages unacceptable levels of vibration when the stages were in motion, and an intermittent sharp squealing when they were at rest, were discovered. In this paper we present the studies that were undertaken to investigate these issues and the solutions that were implemented.

	S.K. Sharma, C. Amundsen, F.A. DePaola, F.C. Lincoln, J.L. Tuozzolo BNL, Upton, Long Island, New York, USA
	A new design was recently proposed for the high power masks and slits of the front-ends at the 2014 MEDSI Conference. The main features of the new design are integrated knife edges in high conductivity copper alloys, interception of the photon beam only on horizontal surfaces, replacing Glidcop® with readily available CuCrZr, and thermal optimization with internal fins. Numerous components based on this design have been built for NSLS-II front-ends and some of the design features have been incorporated into other high-heat-load components such as beamline masks and crotch absorbers. In this paper we describe recent progress at NSLS-II in further advancing this design approach by FE analysis, fabrication and testing.
