Helium-3 cryostats for ARPES

"Wet" and "Dry" Models available

Angle-Resolved Photoemission Spectroscopy (ARPES) is used to study the electronic structure of the surface of solids. The ARPES technique employs a synchrotron or laser beam to interact with a sample, resulting in emission of photoelectrons. By analyzing the energy and momentum of the photoelectrons, the Fermi surface of the material can be mapped. ARPES experiments are often performed in the 2 Kelvin – 10 Kelvin range, but recent research trends often require temperatures below 1 Kelvin (sub-K).

JanisULT is a world leader in the design and manufacture of cryostats for ARPES applications. We choose materials and employ fabrication techniques that are strictly compatible with the most demanding UHV requirements. Our applications physicists are ready to assist you in the selection of a standard or custom designed system precisely configured to meet your unique experimental needs.

Sub-K ARPES
  • Sub-K system developed for high-resolution angle-resolved photoemission spectroscopy below 1 K or other applications with similar requirements.
  • Liquid helium and cryogen-free versions available
  • Cooling provided by a continuous flow He-3 cryostat
  • Bottom loading sample located in UHV environment
  • System can be operated in continuous or single-shot mode
