The Lake Shore CPX-VF probe station enhances the standard probe station capabilities with the addition of a ±2.5 T vertical field superconducting magnet. It can do all the standard C-V, I-V, microwave, and electro-optical probing of the CPX, plus out-of-plane vertical field superconducting magnetic measurements. Researchers can use it to perform Hall effect measurements and test magneto-transport parameters. The CPX-VF is one of Lake Shore’s premium probe stations for combining microwave measurements with magnetic field.

The CPX-VF is designed to enable true 90° wafer probing on wafers up to 51 mm (2 in) in diameter. The sample can be maintained at elevated temperature during cooldown reducing the potential for condensation, a critical requirement for measuring organic materials. The continuous refrigeration station uses liquid helium and can be operated with liquid nitrogen; however, the superconducting magnet requires liquid helium to operate. The CPX-VF operates over a temperature range of 4.2 K to 400 K with the option to extend the base temperature to 2 K.
