3D-vector magnets


	The 3D-vector superconducting magnet of our lab allows to apply a high magnetic field in an arbitrary directions with respect the 3D-axes of the 3-coil-magnet. This magnet uses 3 orthogonal superconducting coils of 0.7, 1 and 7 T respectively. However, the maximum field strength is limited if operated simultaneously, due to high torque forces generated between the coils.


	In this figure is shown the maximum field components that can be applied at the same time to the magnet coils. This limitation is due to strong torque forces generated between the magnets when more than one coil is fed. Trespassing these limits could damage the magnet structure.


	Magnet for He₃ cryostat

This is a scheme of the 3D-vector superconducting magnet placed at the bottom of a cryogenic dewar designed to accommodate the He3 cryostat. The dewar has a main chamber where the magnet is placed. This chamber is completely filled with helium liquid to maintain the cryostat at 4.2K. An external chamber for nitrogen liquid decreases the helium liquid consumption. An external vacuum chamber acts as a shield for the 300K laboratory temperature.


	Magnet for dilution cryostat

		Here we see a second 3D-vector superconducting magnet placed at the bottom of a cryogenic dewar designed to accommodate the He3-He4 dilution cryostat. The system has similar characteristics.
