The technology of non-magnetic fiberglass-based low-noise cryostats housing SQUID systems is extremely demanding. It requires an exact heat-transfer design, minimal use of reflecting metal shields, materials know-how and special manufacturing skills possessed only by a few companies in the world with some of them already being out of business: Hoxan (Japan), CTF (Canada), 2-G (USA), Tristan (USA), CES (USA) and a handful of others. Mesuron Inc. cryostats are superior to all of the above, as described in more details below.

 

Driven by the SQUID technology needs, Mesuron Inc. developed a complete line of cryostats, including several standard series of non-magnetic cryostats, which sell as a part of the system or as stand-alone items. The standard Mesuron cryostat series includes a variety of bio-magnetic and other types of cryostats for both liquid helium and liquid nitrogen. Mesuron Inc. also produces custom-made specialized cryostats, like cryostats that can work in any orientation, including horizontal and upside-down; cryostats with optical windows, cryostats with a record-small measurement distance from the cold liquid inside to the room-temperature surface outside (the "hot-to-cold" distance), etc.

 

Mesuron Inc. fully utilizes the unique knowledge and expertise of its founder, scientist, engineer and inventor

A. Bakharev, who has more than 30 years of research and practical experience in MagnetoCardioGraphy, SQUID magnetometers, with plastics, epoxy resins, types of vacuum-tight connections for extremely low temperatures, as well as specific requirements for the SQUID sensors. Improved nonmagnetic fiberglass cryostat designs were the result of creating a variety of SQUID magnetometers for measuring extremely weak magnetic signals in a magnetically unshielded environment for numerous applications especially for for MagnetoCardioGraphy operating in magnetically unshielded environment such as Hospitals and Emergency Rooms (ER) . MagnetoCardioGraphy SQUID magnetometers based on Mesuron's cryostats perform reliably in an extremely magnetically and radio frequency "noisy" environment, in close proximity to the freight elevators, computers, printers, Wi-Fi hot spots and moving hospital personnel.

Mesuron Inc. cryostats outperform competitors' cryostats due to

  • higher reliability: most of our cryostats have been in working condition for more than 20 years

  • longer helium hold times

  • lighter weight

  • resistance to mechanical damage

  • lower magnetic noise

  • smaller hot-to-cold distances

  • easier access to liquid helium or nitrogen,

  • faster cool down

  • safer operation.

Cryostats Series BA1

 

 

In the Picture:

D1 -An inside diameter of the cryostat neck and cryogenic vessel

D2 - Cryostat outside diameter

L - Length of the cryostat without inserts (cap)

Ln -Cryostat neck length

H - Minimum Hot-to-Cold distance from the sensor to the warm surface of the bottom plate 

 

BA1 cryostat series is popular in research and experiments with large dimension cryogenic devices requiring maximum access to the cryogenic vessel.  We can produce cryostats with L = up to 1000 mm, D1= 200 mm and D2= 260 mm and H = 15-20 MM

The full size cryostat has the volume of about 18 liters and liquid helium evaporation rate of 2-4 liters per day depending on the numbers of the inserts (SQUID magnetometer probes) or the numbers of connecting wires.

Cryostats series BA2

 

 

In the Picture:

D1 - The inside diameter of the cryostat neck and internal cryogenic tail.

D2 - Cryostat outside diameter

D3 -The inside diameter of the cryogenic vessel

D4 -The outside cryostat tail diameter

L - Length of the cryostat without inserts (cap)

Ln -Cryostat neck length

Lb -Cryogenic vessel length

Lti -Internal cryogenic tail length

Ltn -Outside cryostat tail  length

H - Minimum Hot-to-Cold distance from the sensor to the warm surface of the bottom plate 

 

Cryostat design BA2 is popular in the SQUID magnetometers used in small measurement areas, small Hot-to-Cold "H" distance and low liquid helium consumption.  The "H" distance can vary from 7 to 15 mm depending on helium consumption requirements, design and dimensions of the internal tail diameter

D4 - The outside cryostat tail diameter

L - Length of the cryostat without inserts (cap)

Ln - Cryostat neck length

Lb - Cryogenic vessel length

Lti - Internal cryogenic tail length

Cryostats series BA4

 

In the Picture:

D1 - The inside diameter of the cryostat neck and internal cryogenic vessel

D2 - Cryostat outside diameter

D4 - Internal Diameter of the inside cryostat tail

L - Length of the cryostat without inserts (cap)

Ln -Cryostat neck length

Lb -Cryogenic vessel length

Lti - Internal cryogenic tail length

H - Minimum Hot-to-Cold distance from the sensor to the warm surface of the bottom plate 

 

Cryostat design BA4 is used in cryogenic probes or devices requiring large common access to the cryostat which has a small diameter of the sensors area. BA4 provides the smallest "H" distance possible and a cryogenic bulb which is very stable in vibration. Helium consumption is usually better than in the B1 cryostat though it still depends on the "H" distance requirements and the cryogenic insert design in the cryostat neck region.

Horizontal Cryostats series BA5

 

 

 

In the Picture:

D1 - The inside diameter of the cryostat neck and cryogenic vessel

D2 - Cryostat outside diameter

L - Length of the cryostat without inserts (cap)

Lb -Cryogenic vessel length

 

A horizontal cryostat is the most challenging one to design and manufacture.

Mesuron Inc. series BA5 allows for the placement of a cryogenic insert as large and long as the cryogenic vessel itself. As with other Mesuron cryostats, the proprietary cryogenic lock design allows to remove the cryogenic insert out of the cryostat without the need for any special instruments. The cryostat automatically becomes hermetically sealed during the cool down.

Upside down cryostats series BA6

 

 

 

In the Picture:

D1 - The inside diameter of the cryostat neck and internal cryogenic tail

D2 - Cryostat outside diameter

D3 -The cryogenic vessel inside diameter

D4 -The outside cryostat tail diameter

L - Length of the cryostat without inserts (cap)

Ln -Cryostat neck length

Lb - Length of the cryogenic vessel that can be filled with cryogen, may vary on demand

Lti - Internal cryogenic tail length

H - Minimum Hot-to-Cold distance from the sensor to the warm surface of the cryostat bottom plate 

 

BA6 design is used when there is a need for a special access during measurements taking. BA6 can work in any position in relation to the measured object. The maximum cryogen volume in this design is a half of the cryogenic vessel. The cryogenic vessel must be thermo-stabilized in order for all of its parts to have the same temperature as cryogen itself. On  operating only in the upside down position, the cryogen volume can occupy up to 90% of the cryogenic vessel. In this case,  filing it up with cryogen is possible only in the upside down position as well.
