Quotation inquiry catalog.whishlist.tooltip

The Ultra-high resolution Angle Resolved Photoemission Spectroscopy (ARPES) system.

Transferring system:

Flag Style sample holder

System configuration:

- Analysis chamber with double mu-metal liner guaranteed residual magnetic field lower than 0,1 microTesla and base pressure range 5*10^-11 mbar include:

• Close cycle High resolution manipulator with LHe cooling (temperature on the sample down to 15K) – full motorized
• Optimized for extremely demanded applications, high precision ARPES electron analyzer
• Monochromatic UV source for UPS measurement with dedicated pumping system
