5-axis sub-Kelvin Helium-3 cryostat for ARPES

Woburn, Massachusetts, USA – January 20, 2014 - After successfully developing the world’s first 4-axis high power sub-Kelvin He-3 cryostat for Angle-Resolved Photoemission Spectroscopy (ARPES) application in 2008, Janis Research’s ultra low temperature (ULT) group is proud to announce a 5-axis high power sub-K He-3 cryostat for ARPES application has been successfully tested recently, and it has the following performance specifications:

Five (5) degree of freedom:  X-motion, Y-motion, Z-motion, Phi (azimuthal), and theta (tilt)

Base temperature on the rotating/tilting sample holder: 840mK

Azimuthal rotation range: 195 degree

Tilting range: /- 30 degrees

Cooling power with phi =0 and theta = 0: see plot

UHV compatible

Baking temperature: 90 degree C


Tejas Deshpande, Graduate Student at CalTech, and Ashley Huff, Lab Technician at Janis Research, perform a LHe transfer.

Janis Research’s ultra low temperature (ULT) group is proud to announce that it has developed, in collaboration with multi-agency scientific collaboration team called ACTPol, a new pulse-tube cooled cryogenic platform for the Atacama Cosmology Telescope (ACT). The ACT is a six-meter Gregorian telescope located at an altitude of 5,200 meters (17,000 ft) on Cerro Toco, in Northern Chile, and is dedicated to studies of the structure and evolution of the early universe through direct observation of the Cosmic Microwave Background (CMB) radiation at different polarizations and with arcminute resolution.  Please visit www.janis.com/ACTPol_IOP.aspxfor more information.

Custom cryogenic systems meet Sub-Kelvin spm requirements

Janis Research Company Inc

If you need custom designed cryostats and refrigerators to meet Sub-Kelvin Scanning Probe Microscopy (SPM) requirements, check with Janis Research Co., LLC of Woburn, Massachusetts.  They have over 50 years experience designing and manufacturing cryostats to provide quiet, low vibration, and low RF noise environments for atomic resolution scanning probe microscopy.

Janis Custom Cryogenic Systems are built to specification and incorporate a modular design which can provide multiple features in one unit including 0.009 K to 1 K range, UHV < 10^-10 Torr or better, and up to 17 T magnetic fields using solenoid magnets and to 9-4 T or 9-1-1 T using Vector magnets.  For optimum atomic resolution, these robust all-welded systems use proprietary refrigeration designs to eliminate intrinsic acoustic noise.

Capable of B/T of 10^3 T/K, Janis Custom Cryogenic Systems are highly customizable with standard features including all electropolished stainless steel, gold plated copper, silver plated aluminum, proprietary wiring, pre-cooling methods such as mechanical heat switches, and IR shutters.  Fully automatic gas handling systems with a color touch screen provides one-button cool-down.

Janis Custom Cryogenic Systems are priced from $150,000.00 up and include He-3 and Dilution Refrigerator options.  Price quotations are provided upon request.

Janis Research Company Announces Newly Extended Standard Warranty

Wilmington, Massachusetts (July 11, 2012) – Janis Research Company (“Janis"), one of the world’s leading manufacturers of cryogenic research equipment, today announced a newly extended warranty policy for its broad range of cryogen-cooled and cryogen-free products. For orders received after June 30, 2012, Janis will now provide a standard warranty period of three years (36 months) from date of shipment or purchased installation.

"This warranty upgrade is a reflection of our total commitment to quality, reliability, and customer support," said Tom Pasakarnis, Janis’s CEO. “We recognize that purchasing a cryogenic system represents a long-term commitment for our customers and our extended warranty affirms that the commitment is mutual."

Janis’ newly extended warranty covers defects in material or workmanship in new products manufactured by Janis (the “Product" or “Products"). It applies to all Products for which a purchase order has been received by Janis on or after July 1, 2012; Products purchased prior to July 1, 2012 are covered by the warranty policy in effect on the date the purchase order was received.

The full policy, including limitations, can be found on Janis’s website at www.janis.com/Support_Home_KeySupplier.aspx. Please click the link for “Warranty Policy for all orders received after June 30, 2012."

Miniature Transportation Sample Vacuum Chamber for Micro-manipulated Probe Stations

Woburn, Massachusetts – October 22, 2013 – Janis Research Company is pleased to announce that it is offering a patent pending, miniature, transportable sample vacuum chamber capable of maintaining a sample in vacuum during transportation via an atmosphere environment. The vacuum chamber can be used for transferring wafer/substrates under vacuum from a glove box with special environment into a vacuum or cryogenic micro-manipulated probe station (or into a vacuum chamber) and back into the glove box after testing, measurements or preparations. This transportable vacuum chamber protects the wafer/substrates from atmospheric contamination both on loading and unloading.

Unlike a common vacuum load lock the vacuum chamber has the following features.

  • typical sizes of 50 mm diameter and 25 mm thickness
  • no gate valves required
  • very convenient and easy operation
  • low cost
  • mounting of the transportable sample mount without increasing base temperature of the cryogenic probe station
