5T Magnet
Currently this magnet and the test stand are dismantled and not in use.
For measurements in magnetic fields, the former ZEUS compensator magnet is available at DESY. After its dismantling at the ZEUS experiment it has been re-commissioned in the HERA cryogenics hall (building 54). It is a superconducting magnet which is capable of producing fields up to 5 T.
The inner diameter is approximately 28 cm and the length of the coil is around 110 cm. To ensure superconductivity, the coil is kept at 4 K by liquid helium surrounded by a shield of liquid nitrogen, therefore it cannot be moved to the test beam area. Instead we are planning to build up a laser system.
