CPS-CF Helium-Free Cryogenic Probe Stations The Model CPS-CF enables cost effective, stable, reliable and convenient probing of devices and circuits at very low temperatures. Built-in vibration isolation, smart thermal management, and engineered thermal expansion compensation makes this system ideally suited for a wide range of applications spanning from nanoelectronics (graphene research, molecular electronics, etc.) to space based electronics. The system uses closed-cycle refrigerator and proprietary thermal management permitting inexpensive and fast operations. Built-in vibration isolation minimizes the vibrations to industrystandard levels. Ultra-stable micro-manipulated stages permit accurate and reproducible contact of the probe tip on device features. Wide selection of the probes and wafer chucks permit applications ranging from ultraprecise, fA-scale measurements, RF measurements and many more. Key Features - Cost- competitive, stable, reliable, and convenient to use Temperature range from 4.5K to 480K (0.1K accuracy) Closed- cycle refrigerator for cost effective cryogen-free operations Characterization of up to 2” diameter sample 4 micromanipulated probe arms (up to 8 available in optional configurations), with highly accurate XYZ and optionally θ adjustment Thermally anchored probe tips Temperature- controlled radiation shield Clear view top window (high purity quartz) High frequency vibration damping High level of customization to accommodate most exotic probing needs
