Custom Cryogenic Systems

UOR vessel

Meyer Tool & Manufacturing, Inc. builds custom cryogenic systems to customer print or to performance specification.  Systems range in size, complexity and material requirements.  Our engineering and manufacturing staff are well versed in the the intricacies of designing and building custom cryogenic systems.

Construction materials used include aluminum systems, stainless steel, copper shielding, invar and/or G10 supports, cryogenic seals, and multilayer insulation.

We are knowlegeable with sizing requirements for relief systems.  Testing is rigorous, with intermediate in-process testing of pressure and leak tightness being the key to successful assemblies; our sytems are always built from the inside out.

Here are five systems that illustrate our versatility.

This is a cryostat built to customer prints.  The cryostat is used to prepare deuterium pellets for inertial fusion experiments.  It consists of an internal stainless steel liquid helium vessel surrounded by a liquid nitrogen cooled copper shield and multilayer insulation.  The outer stainless steel vacuum vessel provides access to the internal components through o-ring grooved flanges.  Internal supports are constructed of G10.

Mark II Cryostat Assembly

The photo to the left is of a complex Mark II Cryostat which houses radio frequency cavities for accelerator applications.  The cryostat assemblies, one of seven designed and built by Meyer Tool, have been used in synchrotron light sources worldwide.  These cryostats are constructed of both 304 and 316L stainless steel depending on magnetic permeability requirements.  They contain a liquid helium vessel that cools the niobium radio-frequency cavity, a liquid nitrogen cooled copper shield, and an invar support system.  Internal features include indium wire cryogen to vacuum seals and expansion joints on complex tubing in very tight spaces.

Cylindrical cryostat with liquid nitrogen cooled copper shield

Shown to the right is a relatively simple cylindrical cryostat with a liquid nitrogen cooled copper shield.  Both ends of the cryostat are accessible through fully articulated hinged doors.  An internal work space is mounted on rails within the copper shield, while the shield itself is mounted off simple G10 blocks.

CEBAF Cryomodules

Shown to the left is a cryomodule for which Meyer Tool completed prototype work for the LHe vessels, RF cavity tuner assemblies, RF warm window assemblies, end cans, top hat assemblies and cryomodule.  In addition to the prototype work, Meyer supplied 180 cryomodules to the customer over a period of two years.  The cryomodules consisted of 32-inch diameter, 60-inch long vacuum vessels, 50K copper radiation shields, super insulation, supports and components.

Super Conducting Magnet Assembly

Meyer Tool manufactures skid-mounted equipment and components for cryogenic refrigerator/liquefier and applications.  This includes cold box fabrication, coil-wound heat exchangers, oil removal systems and cryogenic transfer piping.  In addition, Meyer designs and manufactures custom cryogenic systems and cryogenic test facility equipment.

The higher the quality, the lower the "total cost of ownership".
