TUPE12 | Developing White Beam Components of TPS Beamline 24A | ion, simulation, laser, target | 183 |
|
|||
The TPS 24A, Soft X-ray Tomography (SXT) beamline, is one of the beamlines in the second construction phase at the Taiwan Photon Source (TPS). This bending magnet (BM) beamline has high flux in the range between 260 eV and 2600 eV. It is designed for transmission full-field imaging of frozen-hydrated biological samples. At the exit slit, the beam flux optimized in 520 eV is 282 billion photons/second with resolving power 2000, the beam size is 0.05 mm × 0.06 mm (V × H, FWHM) and the beam divergence is 1.73 mrad × 1.57 mrad (V × H, FWHM). By contributions of the generic beamline components project in recent years, modular mechanisms would be used in this beamline such as mask, X-ray beam position monitor (XBPM), photon absorber (PAB), and screens. However, these beamline components were designed for ID beamlines, so they should be redesigned for BM beamlines. This paper generally introduce these beamline components decided and redesigned for the TPS 24A. They will play important roles at the BM beam-lines in the future. | |||

TUPE26 | Carbon-Steel/poliethylene Radiation Enclosures for the Sirius Beamlines | ion, radiation, simulation, neutron | 223 |
|
|||
Funding: Brazilian Ministry of Science, Technology, Innovation and Communication Lead enclosures have been used over the past decades for radiation protection at mid and high-energy synchrotron light-sources, requiring nearly 10% of the investment needed to set up a new beamline. Due to the increasing concern about neutron levels, in part due to the reduction of the photon radiation levels with the increased thickness of the hutch walls, the existing constructive models were revisited and a new constructive approach based on Carbon-Steel (CS) and High-Density Polyethylene (HDPE) is proposed for the SIRIUS beamlines, leading to increased overall radiation protection and potentially lower cost. This work is going to show preliminary simulation results, cost-comparison, as well as a few mechanical design details and prototyping initiatives. |

WEPE05 | Innovative Design of Radiation Shielding for Synchrotron Light Sources | ion, radiation, synchrotron, storage-ring | 321 |
|
|||
Over the course of decades, the shape of the bulk shielding walls for synchrotron light sources has developed into a standard configuration, including a ratchet shape of the outer storage ring wall, to accommodate the clearance needs for front end and first optical enclosure assemblies. New state of the art light sources will have low emittance, high energy beams, which will give potential for higher beam losses. These losses will yield higher radiation dose rates at the downstream wall and stricter safety requirements in the first optical enclosure. Throughout the installation of local shields at NSLS-II, verification dose rate studies of various shielding configurations were performed. Analysis of these studies revealed that a circular outer bulk shield wall could greatly reduce the dose rate to the users who work near the front end optical components. This presentation discusses the benefits of this circular bulk shield wall verses the challenges of component installation near the wall and ways to mitigate them. | |||

WEPE30 | Introduction to Neutron Scattering Instruments - How are they Different? | neutron, ion, scattering, GUI | 360 |
|
|||
Funding: The Canadian Light Source is funded by the Canada Foundation for Innovation, Natural Sciences and Engineering Research Council of Canada, the Government of Saskatchewan, and other funding bodies. Neutron scattering is a complementary technique to x-ray scattering scientifically, but while there are similari-ties, there are some unique challenges in the design, con-struction, and operations. This poster will provide a brief description of neutron scattering, describe the technical components of spallation neutron scattering instruments, and discuss the engineering challenges found in the design and construction of these instruments. |
