Lake Shore Cryotronics, a CSA Corporate Sustaining Member, has introduced updated specifications for its Model CRX-VF cryogenic probe station, which features increased maximum magnetic field, improved magnetic field at elevated sample temperatures and improved vacuum performance.

The versatile Model CRX-VF cryogen-free micro-manipulated probe station is used for non-destructive testing of devices on full and partial wafers up to 51 mm (2 in) in diameter. The CRX-VF superconducting magnet platform generates higher fields than are possible with an electromagnet based station without the operating cost of liquid helium. Ideal for measuring electrical, electro-optical, parametric, high Z and Hall effect, as well as DC, RF and microwave properties of materials and test devices, the CRX-VF is widely used to measure nanoscale electronics, quantum wires and dots, semiconductors and spintronic devices.

The product’s specifications have been improved and updated, making it more flexible than ever. The maximum magnetic field capability at base temperature has been improved from ±2.25 T to ±2.5 T. Additionally, the CRX-VF can now be operated up to ±2 T from 10K to 400K and up to ±1 T from 400K to 500K. Previously, only ±0.5 T was possible above 400K and no magnetic field was possible above 450K.

A new high vacuum option has been added as a standard option for customers whose applications require lower base pressures. The PS-HV-CPX option improves vacuum to <5 × 10^-7 Torr with the station at base temperature, an improvement of two orders of magnitude over the standard vacuum configuration. The high vacuum option is recommended for applications sensitive to contamination.
