Special manufacturing/joining techniques used in the manufacture of the Advanced Photon Source (APS) front-end and beamline components

The front ends and beamlines of the Advanced Photon Source (APS) are designed to control, define, and/or confine the x-ray beam. Power densities of the order of 500 watts/mm2 are generated by the intense undulator beams, thus conventional materials and cooling techniques for beam stops, slits and masks are inadequate. Extensive use of Glidcop reg-sign, tungsten and molybdenum has been made in the design of these components; this has resulted in the need to develop and use specialized manufacturing/joining techniques. Experience gained using these techniques for the fabrication of APS front-end and beamline components is presented. copyright 1996 American Institute of Physics
