Cryostat à cycle fermé 1,5 K

Janis - Lake Shore Company

Ce cryo-réfrigérateur à tube pulsé à faible vibration atteint les performances de l'hélium liquide en utilisant une technologie sans cryogène et un système en boucle fermée.

Le modèle PTSHI-950-LT 1,5 K à cycle fermé fonctionne en continu de 1,5 à 300K (450K en option) et constitue une alternative clé en main à l'hélium liquide, sans cryogène.

Caractéristiques
  • Plage de température : ~1,5 à 300K (450K en option)
  • Temps de refroidissement initial du système : ~9h à 1,5K
  • Temps de changement d'échantillon : ~80 min
  • Tête froide : Refroidisseur cryogénique à tube pulsé
  • Environnement de l'échantillon : Vide ou gaz d'échange statique

Standard Configuration

The Janis Model PTSHI-950-LT 1.5 K continuous closed cycle refrigerator cryostat operates continuously from 1.5 K to 300 K (450 K optional) and is a cryogen-free, turnkey alternative to liquid helium. Featuring pushbutton operation including sample temperature adjustment, this top-loading refrigerator can locate samples in either static exchange gas or vacuum, and users can easily change it while the system is operating.

The system offers rapid sample exchange while the refrigerator is operating. The sample is inserted, via a long rod, into a nearly isothermal region of the gas column for cooling. Sample exchange by simply removing the sample rod, switching samples on the rod, and reinserting the rod into the cryostat. The entire sequence takes ~80 min and is performed while the refrigerator is operating.

Capable of achieving 1.5 K in ~9 h, the Janis Model PTSHI-950-LT 1.5 K continuous closed-cycle refrigerator cryostat has a 50.8 mm I.D. sample chamber (optional to 100 mm) and can be designed to customer specifications. The system allows you to cool samples, devices, and/or equipment without the inconvenience and expense of liquid helium.

Neutron scattering configuration

The Model PTSHI-950-LT can be configured for neutron scattering. Modular tails can easily be exchanged for different experimental requirements.

Applications

  • materials research
  • magnetic measurements
  • neutron scattering (see the neutron scattering configuration)
  • electrical transport measurements
  • optical spectroscopy
  • spintronics
