Design and Analysis of a Be Window for the Aps Diagnostics Undulator Beamline
نویسندگان
چکیده
The design of a beryllium (Be) window for use under the extremely high heat load of an undulator beam is one of the challenges for third-generation synchrotron radiation beamlines. A novel design of a Be window is presented for the Advanced Photon Source (APS) diagnostics undulator beamline, whose beam has a peak power density of 150 W/mm2 (7 GeV/100 mA stored beam). The window has a double concave profile with a thickness of 0.5 mm at the center and is brazed to a water-cooled oxygenfree, high-conductivity (OFHC) copper manifold. Finiteelement thermal analysis of the Be window is also presented.

Design of an Undulator White Beam Profiler and Test Results on the APS Beamline
Performance challenges for an undulator XBPM during operation are contamination of the signal from the neighbouring bending-magnet sources and the sensitivity of the XBPM to the ID gap variations. Problems are exacerbated because users change the ID gap during their operations, and hence the percentage level of the contamination in the front-end XBPM signals varies. The smart XBPM system partia...
متن کاملMeasurement of the Aps Storage Ring Electron Beam Energy Spread Using Undulator Spectra
Abstract The angle-integrated flux spectrum of an undulator has sharp dropoffs at harmonic photon energies. Its derivative therefore shows pronounced peaks with rms width ∆ω/ω ~ 0.4/nN, where ω is the photon energy, n is the harmonic number, and N is the number of undulator periods. For the fundamental photon energy of the Advanced Photon Source diagnostics undulator, the derivative of the angl...

Recent advances in X-ray Photon Correlation Spectroscopy (XPCS) use the full bandwidth of an undulator harmonic in order to maximize the coherent flux for small angle X-ray scattering experiments. X-ray mirrors and filters are typically used to select a given harmonic of the spectrum. At the University of Michigan/Howard University/Lucent Technologies, Bell Labs, Collaborative Access Team (MHAT...
متن کاملPhoton Diagnostics for the X-ray FELs at TESLA
An X-ray diagnostic station will be installed for each of the XFEL undulator beamlines at TESLA. Primary purpose of the X-ray diagnostics is to provide an additional tool for alignment and commissioning of the numerous undulator cells along an XFEL beamline independently from electron beam based alignment procedures. Both methods will complement one another. The X-ray diagnostic station will be...
متن کاملRadiation Shielding of Insertion Device Beamlines Using a Mirror as the First Optical Element
The radiation shielding for an Advanced Photon Source (APS) insertion device beamline using a mirror as the first optical component is discussed. The beamline layout for a specific Synchrotron Radiation Instrumentation Collaborative Access Team beamline (sector 2 of SRI CAT) is described, and the methodology used to determine the radiation shielding is presented. Results indicate that, by using...
