High-Precision Positioning Mechanism Development at the Advanced Photon Source
نویسندگان
چکیده
There are many challenging tasks in the design of the beamline instrumentation that relate to high precision positioning mechanism for users at a third-generation synchrotron radiation source, such as the 7 GeV Advanced Photon Source (APS). Over the last few years, progress has been made in the development of novel mechanisms with high positioning resolution and high stability at the APS. Applications include: a high-energy-resolution monochromator, x-ray nanoprobe scanning stages, and a sample-exchange automation system for x-ray cryobiocrystallography. In this paper, the particular design upgrades, as well as the new mechanism design specifications, are summarized.

Progress towards a Revolute-joint Robot for the Precision Positioning of Material Samples or an X-ray Detector
At the Advanced Photon Source (APS), the desire to combine sample handling, sample positioning or goniometer functionality into one piece of equipment has provided the impetus for the development of a precision six degree-of-freedom robot with approximately 2 μm dynamic positioning uncertainty. This specification is driven by the need for a positioning uncertainty that should be 10 to 20 percen...
متن کاملDesign, Modeling and Experiments of An In-pipe Magnetostrictive Impact Drive Mechanism
This paper presents a magnetostrictive in-pipe impact drive mechanism (IDM). To estimate the output performances of the IDM, a dynamics model was developed based on the magnetostrictive material constitutive model and mechanical model of the IDM. Therefore, an experimental system has been built to test the motion performance of IDM. Simulation and experimental results illustrate that the propos...

This paper applies a combined precision stage to fabricate micro-structures by two-photon polymerization (TPP). The combined stage consists of PZT and stepper-motor stages to achieve precision positioning in long displacements. First, we derive the models of the stages by identification experiments. Second, we apply robust loop-shaping techniques to improve the positioning performance of the st...
