Abstract: The design of a high precision optical table with two degrees of freedom. The table will be for use with surface optical table applications as well as other engineering experiments. It will provide a surface with rock solid stability and rigidity to support demanding research applications. The flatness of the table is an outstanding <±0.004 inch flatness over two square feet, and is combined with several frequency damping measures both in the work surface and the base of the optical table. Experimental apparatus' mounted on the work surface can be positioned and oriented anywhere in three-dimensional space within the limits of travel via high precision X- and Z-axis motion stages, specifically four jacks, two slides and two free slides.

Abstract: The design of a high precision optical table with six degrees of freedom. The table will be for use with surface optical table applications as well as other engineering experiments. It will provide a surface with rock solid stability and rigidity to support demanding research applications. The flatness of the table is an outstanding <±0.004 inch flatness over two square feet, and is combined with several frequency damping measures both in the work surface and the base of the optical table. Experimental apparatus' mounted on the work surface can be positioned and oriented anywhere in three-dimensional space within the limits of travel via high precision X-, Y-, and Z-axis motion stages, specifically three jacks and three slides arranged in a 3-point kinematic fashion.

Abstract: An ionization chamber that serves as a radiation detector/beam position monitor for beamline applications. When two chambers are paired together in a 90° rotation orientation, the device can be used for beam position monitoring, detection and recording of location of beam bunches moving within the beamline, by detecting horizontal and vertical beam position. This feature allows for ease of use as well as multiple use applications for the chambers, resulting in the need for less additional parts.

Abstract: In this paper we will describe the design of a silicon mirror system. The mirror system consists of five primary subcomponents. The mirror optic itself, its positioning system, the bending mechanism, a vacuum chamber, and the support structure all provided as an integrated package. All subsystems were designed to provide the highest positional stability and structural rigidity with precision motions on all axes.

Abstract: The following precise optical slit design was analyzed in order to optimize the actuator loads, flexure stresses and heat transfer characteristics. It was shown, that monolithic flexure (made out of GlidCop) with out of vacuum water cooling piping shows adequate performance. Even for a minimal flow conditions (1.0 gal/min without spring inserts), the maximum temperature of the flexure does not exceed 90° C. for 60 W deposited power and following the same design principles 150 W power load is visible, as a Von Mises thermal stress does not exceed even half of a fatigue strength for GlidCop. Steady state thermal loads reduce the blade clearance by 50 ?m (total) at the worst case scenario, but such load does not lead to blade clash, and maximum angular deviation of the slit blades at full stroke is less than 16 ?rad per blade, well within the +/?2 mrad requirement.

Abstract: A system of outer supports for in vacuum girders driven by two lead screws, supported at the approximate quarter points and a second set of less massive in vacuum girders. The embodiment of the design is comprised of two spherical joints, outer holds bellows, inner threads into the girder, and split coupling. This invention makes changing bellows easier, allowing for bellow replacement without disturbing magnet shimming. This system provides the overall rigidity necessary to maintain the required straightness and flatness of the magnet modules over a range of magnet gaps and varying attractive magnetic forces.

Abstract: A small superconducting undulator with a period less than 1 cm, referred to here as a “super-mini” undulator. The embodiment of the super-mini encompasses of two coils wound bifilarly around a pair of bobbins in a racetrack configuration, such that the currents in adjacent coil segments run antiparallel to each other. If such coils are arranged alongside each other, separated only by a small gap on the order of a couple of millimeters, a spatially alternating magnetic field is produced that makes a passing electron beam undulate and emit undulator radiation. The wound bobbins are mounted within a frame and combined with upper and lower pole pieces to close gap between the wire coils.

Abstract: A procedure for polishing slit blades to ensure proper flatness and blade angle. This task is incredibly difficult. The number of strokes, series of and type of abrasive papers used, direction of polishing lapping strokes, as well as other practices to promote flatness and minimize human and manufacturing error in the final slit blade product have all been experimentally determined by ADC personnel over years of experience and study. A fixture for holding blades while polishing the blade angle side has been developed to accommodate precise blade angle polishing.
