TPS 27A beamline is powered by an elliptically polarized undulator (EPU) with magnets at a 66 mm period length, and photons are monochromized by active gratings to cover an energy window of 90 to 2200 eV at a resolving power of 10,000. The beamline is to host two microscopes in separated branches.
At first branch, the planned microscope is a zone-plate based scanning transmission X-ray microscope (STXM) designed to record both absorption-based images and coherent diffraction images (CDI).
The second branch is to host a photoelectron related imaging and nanospectroscopy (PRINS) station. With an imaging type electron column integrated with a double hemispherical electron energy analyzer, the microscope at PRINS station is an energy-compensated full-field microscope capable of collecting photoelectrons in either real-space or momentum-space mode.
With the capabilities described above, the Nanoscopy beamline is expected to attract a broad range of domestic and international users whose expertise includes environment, energy, polymer, magnetism, semiconductor, and low-dimensional physics and chemistry.
