Radiation effects studies at the Advanced Photon Source

*Radiation Effects Studies at the Advanced Photon Source

At the Advanced Photon Source (APS) concern for radiation-induced demagnetization of the insertion devices (IDs) in the storage ring and in the free-electron laser has initiated systematic radiation effects studies towards the development of efficient techniques for ID protection. The studies include radiation dose monitoring, parametric study of the radiation-induced demagnetization, as well a...

The Advanced Photon Source a National Synchrotron Radiation Research Facility

Impact of Gas Bremsstrahlung on Synchrotron Radiation Beamline Shielding at the Advanced Photon Source+

The Advanced Photon Source (APS) currently under construction at Argonne National Laboratory will be one of the world’s brightest synchrotron radiation facilities. The storage ring, capable of storing currents up to 300 mA at 7.0 GeV and 200 mA at 7.5 GeV, will produce very intense and energetic synchrotron radiation (Ec = 24 keV for bending magnets and Ec = 37.4 keV for wigglers, where Ec is t...

The Cryogenic Cooling Program at the Advanced Photon Source

This paper describes the experimental and analytical program in cryogenic cooling of high-heatload optics at the Advanced Photon Source. A prototype liquid nitrogen pumping system has been procured. This pump provides a variable flow rate of 1 to 10 gpm of pressurized liquid nitrogen and is sized to handle up to 5 kW of optic heat load. Also, a high-vacuum, doublecrystal monochromator testing t...

Magnetic Performance of Insertion Devices at the Advanced Photon Source

The insertion devices (IDs) at the Advanced Photon Source have been magnetically tuned to minimize the integrals of the field through the devices and to minimize the variation of those integrals with gap, with a goal of not perturbing the stored particle beam. Measurements of the particle beam motion as the ID gap was changed found that the closed-orbit distortion was better than the requiremen...
