Csi-Lab-ARPES

HR-ARPES200

The High Resolution Angular Resolved Photoelectron Spectroscopy System, with high energy resolution and ultra-low temperature characteristics, is specifically designed for high-resolution angle-resolved photoelectron spectroscopy applications.

The system incorporates a unique structural design, including analysis chamber, transfer chamber, and load chamber with different functions.

The analysis chamber is equipped with R200D hemispherical electron energy analyzer, monochromated UV source, open/closed-cycle 6-axes manipulator, sample transfer tools, and vacuum components.

The analysis chamber adopts an integrated design, with the upper part for sample transfer, the middle part of analysis, and the low part for pumping. A double-layer μ-metal shields is equipped for magnetic shielding.

Transfer chamber is used for sample transfer, annealing and cleaning. An argon gun could be installed above the annealing stage for in situ argon ion cleaning and annealing.

Load chamber is used for loading samples from atmospheric. Direct connecting to glove box or suitcase from load chamber is available.
