Angle resolved photoemission spectroscopy (ARPES) is arguably the most powerful and direct experimental technique available to study the electronic structure of a material. Our new Spin-ARPES setup at the SUV beamline of Singapore Synchrotron Light Source is a dedicated facility for investigating solid surfaces and thin-film materials. Our ARPES setup incorporates state-of-the-art Scienta-Omicron DA30L electron analyzer and two orthogonally mounted Mott spin polarimeters to map three-dimensional (vectorial) spin texture of electronic bands. The new class of deflection analyzer, which utilizes a set of electrostatic lensing systems, enables us to perform a full Fermi mapping without rotating/moving the sample. Also, the deflection functionality allows us to scan spin resolved energy distribution curves (EDC) at any point (within the deflection limits of ±15°) of the Brillouin zone electronically. Presently, we are using a helium lamp source (primary energy 21.21 eV) as photon source with plans to incorporate the synchrotron light and a laser source in the future. Our liquid helium cooled cryo-manipulator enables us to perform measurements at room temperature down to 5 K. Our Spin-ARPES station is also integrated with our Pulsed Laser Deposition (PLD) growth chamber for in-situ growth and measurement. In summary, we offer a comprehensive materials research program encompassing material design and growth, advanced characterization, and theoretical simulation (e.g., Density Functional Theory), to enable the investigation and discovery of novel materials.
