Vertical Test Station for magnets


Can accomodate magnets up to 700 mm dia x 6500 mm in length maximum weight 10 ton

Soon to be integrated by a 515 mm dia x 3300 mm vertical cryostat for medium-size magnets/samples

480 mm dia x 1200 mm, and other smaller cryostat

  • Max operating pressure 4.5 bar Thermal shield cooled by LN or evaporated GHe
  • Variable temperature for High Temperature Superconducting magnets tests is foreseen



            Mechanical Measurement Laboratory


Measurements of yield strength, Young’s modulus, section reduction, elongation, ultimate stress e strain are possible.

To this aim the following testing machines are used:


  • INSTRON mod. 6027, tensile and compression tests, according to the guidelines of ASTM EN-85, at room and cryogenic temperatures.
  • MTS mod. 810, toughness test according to the guidelines ASTM EN-85, at room and cryogenic temperatures.
