UHV System Description

ARPES System is a customised multi-chamber UHV system dedicated for investigation of physical properties (electronic band structure) of high temperature superconductors - University Fudan, China.

• Multi technique analytical chamber integrates different surface analysis methods; Monochromatic UV Photoelectron Spectroscopy (UPS) and LEED.

• Sample positioning is via a stable, high precision, 5 axis manipulator with all axes motorised for automatic surface mapping.

• The sample receiving station is equipped with a closed cycle helium cryostat that allows temperature variation over the range 10K to 400K.

• The Chamber is fabricated from mu-metal and designed for energy resolution better then 0.5 meV, being equipped with a hemispherical analyser with 2D detector, monochromatic UV source and a LEED system. The flexible design allows for easy modification to meet future scientific demands.

• The system is designed so that it can be used in the laboratory as well as on a synchrotron beam line. The analyser is mounted horizontally and can be easily rotated by 90 degrees. The frame has easy height and x-y adjustment for quick and easily reproduced alignment to an external light source (synchrotron or LASER).

• Single level preparation chamber equipped with ion source and mass spectrometer and several ports which can be used in future for other preparation devices.

• Load lock chamber for loading up to six samples and internal bakeout facility.

• Sample park chamber for 6 sample holders.
