Abstract:
The photoelectron related image and nano-spectroscopy (PRINS) end-station at the Taiwan Photon Source (TPS) 27A2 branch is now hosting a photoelectron-based momentum microscope (MM) [1], which equips with an imaging-type electron column integrated with a hemispherical electron energy analyzer and an imaging spin filter, so the MM is able to acquire both position-resolved and angle-resolved photoelectron spectroscopy with spin contrasts. Although the soft X-ray beamline (TPS 27A) is still under construction until the end of 2023, the off-line commissioning of the PRINS end-station by two in-house ultraviolet photon sources has delivered preliminary results and proven its basic performance [2].
In this report, I will first demonstrate the performance of the momentum microscope illuminated by a Hg lamp and Helium-I radiation, and then shed light on what can be achieved when the circular-polarized X-rays and the imaging spin filter are available in the near future.
