The photon-energy ranges available at BL-13 are 48−2000 eV for the horizontal linear polarized light, 102−2000 eV for the vertical linear polarized light, 74−700 eV for the left and right circular polarized lights, and 59−2000 eV for the left and right elliptical polarized lights.
A photoemission spectrometer is permanently installed at the first focal position in BL-13B, so that you can perform soft X-ray absorption spectroscopy with a small spot of 80 μm (horizontal) ×15 μm (vertical) approximately.
A near-ambient-pressure X-ray photoelectron spectroscopy brought in by a user is installed at the second focal point in BL-13B.
A photoelectron spectroscopy brought in by a user which can precisely control the sample temperature is installed at the intermediate position between the first focal position and the second focal position.
You can install your own apparatus to the free port in BL-13A to conduct your experiment.

Special notes
Typical photon intensity drop in the carbon K-edge region（hν = 275 - 295 eV）is around 4% at most.
A mirror for higher harmonics suppression and a higher harmonics filter are installed at BL-13B./li>
Sample size under 10 mm square is recommended.
Users are permitted to bring in their own apparatus to BL-13A. The pressure at the connecting chamber to the BL should be under 10-6 Pa. The synchrotron radiation is at a height of about 1200 mm from the floor. A top view of the beamlines and experimental area.
