X-ray Beamlines On A Superconducting Wavelength Shifter

A Superconducting Wavelength Shifter (SWLS) insertion device with peak field of 6 Tesla has been installed in the Taiwan Light Source (TLS) storage ring to increase the critical energy of the radiation spectrum from 2 keV to 9 keV. We are constructing three hard X-ray beamlines BL01A, BL01B and BL01...

Description
Summary:A Superconducting Wavelength Shifter (SWLS) insertion device with peak field of 6 Tesla has been installed in the Taiwan Light Source (TLS) storage ring to increase the critical energy of the radiation spectrum from 2 keV to 9 keV. We are constructing three hard X-ray beamlines BL01A, BL01B and BL01C to utilize the photon source generated by this insertion device. The beamline BL01B is a DCM X-ray beamline with a toroidal focusing mirror, which provides monochromatic photon beams with energies from 5 keV to 20 keV for X-ray scattering experiments. At the sample position, the expected photon flux is about 7X1011 photon/sec/200mA with an average energy resolution (E/E) of 1X10-3 and the focused beam size is about 1 mm X 0.4 mm. The beamline BL01C is a standard DCM X-ray beamline with both collimating and focusing mirrors, which will deliver monochromatic photon beams with energy ranging from 6 keV to 33 keV for EXAFS and powder diffraction. At the sample position, the expected photon flux is 1X1011 photon/sec /200mA with an average energy resolution (E/E) of 1.6X10-4 and the focused beam size is about 0.9 mm X 0.2 mm. The beamline BL01A is a white-light beamline reserved for other applications. Both BL01A and BL01B beamlines have been constructed and are in commissioning. An average photon flux of 3X1011 photon/sec has been obtained at beamline BL01B.
