10 K CCR cryostats

CCS-800

10 K CCR cryostat features

  • Top-loading static helium thermal exchange gas configuration
  • Closed-cycle cryocooler design allows nearly unlimited unattended operation
  • Choice of cryocooler to match performance and budget requirements
  • Optimized for two-loop temperature control; helium thermal exchange gas is heated and controlled by one heater and calibrated silicon diode, while a second heater and sensor on the sample mount enable rapid temperature sweeps and precise sample temperature control
  • Sample is accessed by removing the top‑loading sample positioner
  • Integrated pneumatically isolated support stand minimizes line broadening due to sample vibrations
  • O-ring sealed ports accept DC and RF electrical feedthroughs
  • Optional DC and RF wires and cables for electrical measurements

Lake Shore offers a variety of 10 K cryostats

Sample in vacuum

Available with SHI cold heads or CTI cold heads. Optical versions include both standard and high temperature. Compact optical come as standard, subcompact, or rotatable versions. There is also a non-optical version. Compact non-optical versions come in both standard and subcompact.

Sample in exchange gas

Available with SHI cold heads or CTI cold heads. Exchange gas cryocoolers are available in both optical and non-optical versions, with the cooler mounted either above or below the sample chamber.

Vibration-isolated

Vibration-isolated cryostats come in standard, UHV, or microscopy configurations.

Vibrating sample magnetometry (VSM)

Available with SHI cold heads or CTI cold heads. Cryostats for VSM are sample in exchange gas.

Mössbauer spectroscopy

Available with SHI cold heads or CTI cold heads. Cryostats for Mössbauer spectroscopy are sample in exchange gas.

Ultra-high vacuum (UHV)

Available both as non-bakeable CCRs with conflat flanges and UHV-compatible thermometry and wiring or as bakeable CCRs.

Cryogen-free 10 K CCR cryostats

When combined with an automatic temperature controller, Lake Shore CCR cryostats become powerful tools for studying the properties of materials over a wide range of temperatures. (These pages describe systems with base temperatures from 8 to 15 K. Lake Shore also offers systems with base temperatures to 4 K.)

As the name implies, closed-cycle systems recirculate a fixed volume of gas to provide cooling to the sample mounting stages, and no gas is added or removed during operation. Lake Shore CCRs use the Gifford-McMahon thermodynamic cycle, based on the controlled compression and expansion of helium gas. A compressor is used to provide the high-pressure helium gas needed for the cycle. Flexible metal gas lines deliver the compressed helium gas to the cryocooler and return the low-pressure gas to the compressor for recirculation. The cryocooler includes two cold stages, one for cooling the sample and one for cooling a radiation shield that surrounds the sample.

CCR systems are available in two general configurations: sample in vacuum (cold finger), and sample in exchange gas (top loading). Within these broad categories, optical, non-optical, compact, and subcompact designs are available, some with a temperature range to 475/700 K. Lake Shore also offers systems for specific applications, including Mössbauer spectroscopy, VSM, and Hall effect measurements.

Our experienced staff of physicists and engineers are also available to assist in custom designing a system to meet virtually any experimental requirement. Complete systems are available including CCR, temperature controller, and vacuum pumping station. Thank you for considering a Lake Shore CCR cryostat—we look forward to becoming your partner in research.
