Horizontal test station for accelerator magnets

Test of superconducting accelerator magnets in their own horizontal cryostat, cooled by 4.5 K He stream at pressure up to 7 bar (supercritical He), and powered up to 20 kA  also in ramped mode.

 

Technical Means:

  • Cooling power of 200W plus 500W at shield temperature;
  • Alternatively 120 l/h liquefaction capability;
  • He gas storage 360 mc (30 mc @12bar)
  • SFC 200 kW He compressor (70 g/s flow rate)
  • Two quadrants power converter of 20 kA +50/-40V, 3kA/s ramp rate;
  • 20kA HTS current leads;
  • 20 ton crane, 9 m clearance, in the laboratory

 

Interno

 

 

fumetto

The installation is new (partially commissioned in 2016).

  • Its first use is foreseen in 2018 for testing the FAIR SIS100 quadrupole doublets

 

Technical steps and expertise:

  • Construction of magnet interface according the specific requirements,
  • Cool-down of the magnet by means of closed cycle GHe for the measurement run,
    • 4 channel QDS system
    • 24 ch temperature monitoring for the magnets,
    • HV insulation tests, flow tests on the magnets
    • NI fast DAQ
