Implementation of Horizontal Focusing Optics at Aps
Despite the very small electron beam emittance in thirdgeneration light sources, the horizontal size of the emitted x-ray beam is still determined mainly by the electron beam divergence. Providing a converging electron beam in an undulator straight section can significantly decrease the spot size of the downstream x-rays, which leads to an increase in the photon flux density on the user sample....
متن کاملThe Control System of Bsrf Topography Station Based on Pc
The X-ray topography station and attached beam line 4W1A are part of the Beijing Synchrotron Radiation Facility (BSRF) to employ the bright synchrotron radiation from the Beijing Electron Positron Collider (BEPC). The main purposes of the station are used for the study of the perfection of single crystals, high resolution multi-crystals diffraction and Xray standing wave research. The intense p...

متن کاملRecent Developments in Adaptive Optics for the LCRD Optical Ground Station at Table Mountain
The NASA Laser Communications Relay Demonstration project plans to launch an optical payload onboard a satellite destined for a geostationary slot between 60 degrees and 161degrees West latitude. The payload consists of two optical heads with control electronics that relay data between two ground terminals. Current plans call for demonstrating the relay link between ground terminals in Hawaii a...
متن کاملLifetime Studies at the Aps
Plan The studies presented in this note are focused on the lifetime characterization with positrons for the symmetrical low βy lattice. Before switching back to electrons, detailed lifetime studies were performed in order to gather data that could be compared to similar ones with electrons, the ultimate goal being to define a model that could be used to predict lifetimes. The report is divided ...
