two.2.4) Description of the procurement

The solenoid magnet shall generate a 3 T horizontal field. The magnet shall be positioned on a 30 kV

platform, feature a hall probe. The field homogeneity and field axis shall be reproducible after de- and reenergization of the system, i.e. no mechanical adjustment nor magnetic field measurements are required after each cycle.

The cryostat hosting the magnet shall be positioned on the 30 kV platform. It shall be equipped with

adequate cryogenic instrumentation for its operation (e.g. temperature sensors, controllers, heaters

and liquid He level sensors). The cryostat shall comply with EN 17527 for helium cryostats.
