Cryogenic introduces the new CFM-VSM (v2)

Cryogenic launches the new CFM-VSM (v2).  With years of continuous product development, the second generation VSM system offers unique competitive features to ensure highest performance in the investigation of Electrical, Magnetic and Thermal properties of materials at temperatures ranging from 1.6 K to 400 K and magnetic fields up to 9 Tesla – all without the need for liquid cryogens.




Our key improvements include:

Mechanically compensated VSM drive:
Eliminates vibrational coupling between the drive and pick-up system
Assures highest sensitivity for low signal samples
Improved sample alignment:
Ensures the probe is stationary and sample is precisely at the centre of the pick-up system
Assures long term reliability and reproducibility.
Pick-up system mounted rigidly to the VTI top flange:
Ensures that the coil set is properly fixed and does not tilt away from the system axis.
Leak tight exchange gas sample space:
Removes the risk of blocking the VTI circuit when changing measurement probes. 
Allows fast sample change.
Pick-up coil support tube electrically isolated from cryostat:
The support is electrically connected to the ‘clean’ ground and so provides better electrical screening
Integrated electrostatic screen
Reduces noise, improving S/N ratio and so generating better data.

Automatic needle valve:
Software-controlled, stable and assures long term continuous operation.


Actively Shielded NAB Spectrometer

Cryostat houses eleven separate superconducting cryogen-free magnets producing a complex field profile along a central gold-plated UHV cold bore tube.

Used to make precision neutron decay measurements and test the weak interaction in the Standard Model of particle physics.
The results will provide important inputs for astrophysical processes
Key measurements will be of the electron-neutrino correlation parameter, and the Fierz interference term in neutron beta decay
