Closed loop superconducting magnet CCMS-7 up to 7T magnetic field strength

CCMS-7 Overview

With the development of superconducting low-temperature technology and the discovery of new superconductor materials, superconducting magnet technology is also developing rapidly, superconducting magnet technology is a very promising technology in modern science and technology and life as an important role, has its unique application advantages and market demand, to create more possibilities for human life and scientific and technological progress in high-energy physics, controlled thermonuclear reactions, plasma physics, biophysics, cryophysics, magnetism, material structure analysis, medicine, transport and many other scientific research and study is getting more and more widely used. It is more and more widely used in high energy physics, controlled thermonuclear reaction, plasma physics, biophysics, low temperature physics, magnetism, material structure analysis, medicine, traffic and many other scientific exploration and research.

The closed-cycle superconducting magnet CCMS-7 is a pulsed-tube chiller with bellows for enhanced vibration damping, and the intrinsic vibration of the magnet is at the 100 nm level, which makes it particularly suitable for Raman spectroscopy or the rest of the spatially compact coupling of magnetic environments.

Features:
- Closed-cycle refrigeration for pulse chiller;
- Double bracket bellows vibration damping;
- 50mm room temperature bore;
- Up to 7T magnetic field strength;
- Thickness less than 175mm;
- With 350mm slide in X direction and 13mm fine adjustment in YZ direction;
- Support customised coupling bracket.
