X-ray beam stabilization at BL-17A, the protein microcrystallography beamline of the Photon Factory

BL-17A is a new structural biology beamline at the Photon Factory, Japan. The high-brilliance beam, derived from the new short-gap undulator (SGU#17), allows for unique protein crystallographic experiments such as data collection from microcrystals and structural determination using softer X-rays. However, microcrystal experiments require robust beam stability during data collection and minor f...

Neural Imaging Using Single-Photon Avalanche Diodes

Introduction: This paper analyses the ability of single-photon avalanche diodes (SPADs) for neural imaging. The current trend in the production of SPADs moves toward the minimumdark count rate (DCR) and maximum photon detection probability (PDP). Moreover, the jitter response which is the main measurement characteristic for the timing uncertainty is progressing. Methods: The neural imaging pro...

The Hst Snapshot Imaging of Bl Lacs

Using Hubble Space Telescope and WFPC2 we obtained short exposure images for a hundred of BL Lac objects. The targets were centered mostly in the PC using the F702W lter. Sources from various samples, including objects of very diierent redshift (0.05 to 1.2), have been observed. We are able to resolve 66 objects (53 with known z) in the redshift range up to z 0:7. The high resolution and homoge...

A New XAFS Beamline NW10A at the Photon Factory

A new XAFS beamline NW10A using bending magnet radiation from 6.5 GeV PF-AR has been constructed. NW10A consists of a Si(311) double crystal monochromator and a Pt-coated bent cylindrical focusing mirror and provides focused X-ray beam between 8 and 42 keV. The obtained flux through a 1mm square slit is 1×10 ph/s at 20 keV and 7×10 ph/s at 30keV, which are 20 and 200 times more intense than obt...
