Cryogenic Thermal Vacuum Cycling

Small Cryogenic Thermal Vacuum Cycling - Test Dewar n°2

Callisto's test service provides a flexible solution to evaluate the performance of components at cryo temperatures, priced on a per-test basis and thereby minimising cost for the customer. The comprehensive service includes:

  • Test planning, feasibility assessment, evaluation of test requirements and definition of needs for test jigs, interface adapters etc,
  • Provision of any necessary test jigs, adapters interface cables or transmission lines,
  • Installation of components to be tested,
  • Operation of cryogenic test Dewar and associated monitoring Equipment,
  • Conducting or assisting in running measurements on components,
  • RF instruments (Vector network analyser operating up to 40GHz, Spectrum Analyser, etc...)

Examples of components requiring testing are listed below, spanning the radio-astronomy, earth observation satellite, air-borne imaging systems, medical imaging and computing sectors:
- Ultra-low noise RF LNAs, mixers, filters, connectors and components,
- Superconductor (HTS or LTS) components,
- Infra-red detector components,
- On-board space craft instrument components (optical, radar and electrical),
- Any electrical or mechanical component destined for use in cryogenic assemblies (e.g. imaging and medical instruments).
- Mechanical assemblies such as bonded parts.
