Job Description

Hybrid cryogenic systems

This project will set out to study the useful solidification of Nitrogen and other gases for use as cryogens in OpenStar’s magnets.

Cooling superconducting magnets is at the core of OpenStar’s magnet and fusion technology. While many liquid cryogenic systems are available, the potential advantage of solid cryogens offers a significant performance advantage.

The candidate’s work will add frozen nitrogen as an available cryogen for OpenStar experiments. A capability that is not available commercially.


The student will:

  • Complete mechanical and thermal CAD design of a Nitrogen “freezer”
  • Issue parts for manufacture
  • Assemble and test the device’s ability to freeze liquid nitrogen in useful quantities
  • Establish and carry out the necessary safety procedures for working with Solid Nitrogen.


Must have - thermal papers within mechanical engineering or chemical process engineering

Applicants must have completed at least their 3rd year of an undergraduate mechanical engineering or chemical process engineering degree.

Applicants must have experience with 3D-CAD modelling, an understanding of mechanical stress/strain, and an understanding of electrical concepts.

Nice to have - Experience with thermal expansion/contraction, FEA experience (ansys/comsol), cryogenics, design for manufacture

Employment Details

Employment Type: Fixed-term internship.


  • $27.80 per hour - 400 hours.
  • 3% employer kiwisaver contributions.
  • 8% pay-as-you-go holiday pay.
