1. Introduction

After disassembly of NE5A, which was one of the oldest experimental station at the PF-AR, we have constructed a new bending magnet beamline, NE7 (BM), at the PF-AR NE experimental hall using the parts of beamline components of NE5A to begin experiments in 2009 on X-ray diffraction experiments under high pressure and temperature, and X-ray absorption-contrast imaging, such as micro-angiography, monochromatic X-ray CT and X-ray fluorescent CT.

The large experimental equipment, MAX III, for the high pressure and temperature experiments, was transferred from BL-14C2 to NE7A to install at the back of NE7A hutch, where available photon flux at 50 keV is approximately twice larger than that available at BL-14C2.

Users can use white X-rays or monochromatic X-rays, which energy range is from 25 keV to 55 keV, using a double crystal monochromator.

2. Perdormance of beamline

Figure 1 shows the plan view of NE7A at the PF-AR NE experimental hall. A double-crystal monochromator was installed to produce X-ray photons in the range of 25 keV to 60 keV. Figure 2-1 and 2-2 show the photographs of NE7A hutch. Table 1 shows the specification for experiments.
