BL19B2 Abstract
BL19B2 is a bending magnet beamline operated for the purpose of promoting the versatile use of synchrotron radiation in industrial research. For more detail, click here.
The optics has a standard double-crystal Si (111) monochromator followed by two 1-m long rhodium-coated flat silicon mirrors, enabling the use of both direct beam from the monochromator and parallel-reflected beam. The net plane of the crystals can be switched between Si (111) and Si (311) by rotating the crystals. The first crystal is flat and cooled indirectly.
The glancing angle of the mirrors can be changed between 0 and 6 mrad according to the desired cut off energy for higher harmonics rejection. The meridional curvature of the mirrors provides vertical focusing of the beam.
The X-ray energy is tunable over a range of approximately 5-100 keV. The beamline optics are adjusted to fix the beam position at the sample within 0.1mm vertically, and 0.2mm horizontally in the Brag angle range of θB=5-25°. Outside this range, special care has to be taken for the experimental set-ups since the position of beam axis may change abruptly.
