Lake Shore Cryotronics will be at next week’s International Microwave Symposium (IMS) in Boston to discuss cryogenic probe stations, cryostats, and other cryogenic measurement and control products for high-frequency material and device research.
Cryogenic probe stations benefit early-stage research requiring fundamental I-V, C-V, and other electrical measurements of test structures, including those for MMIC or LNA designs. In these applications, there is often a need for non-destructive RF/microwave measurements as a function of temperature within a controlled environment. Lake Shore probe stations provide this control, with temperatures as low as 1.6 K, configurations supporting RF probing up to 1 GHz and GSG RF/microwave probing up to 67 GHz, and magnetic field capability if required.
Various models are available, including the affordable liquid cryogen TTPX station for probing full and partial wafers up to 51 mm (2 in) in diameter (this model will be on display at IMS) and the premium cryogen-free CRX-4K station. The CRX-4K cools down unassisted to as low as 4.5 K and can be specified with an optional 2 W CCR cold head for microwave/RF researchers requiring higher cooling power.
Also available for researchers requiring highly controlled low-temperature environments are Lake Shore cryostats, including models optimized for thermally stable operation in sensitive RF and microwave experiments. On display at IMS will be the CCS-100 optical cryostat, a closed-cycle model that provides <4 to 325 K cooling without using LHe. Also of interest to IMS attendees: the CCS-CP, a <4 K to 300 K cryogen-free cryostat with a large sample space. It is ideal for microwave/RF device testing and prescreening quantum devices, and can be ordered with DC and high-density RF feedthroughs with wiring.
Plus, for researchers requiring a liquid cryogen cryostat, Lake Shore will be available to discuss its wide selection of LHe and LN2 models. In addition to LHe systems optimized for <2 K studies, cryostats are available for ultra-high vacuum and magnetotransport measurement applications.
And for cryostat users dealing with helium supply issues, Lake Shore offers Infinite Helium™, an award-winning, fully automated recirculating gas cooler system that enables an LHe cryostat to operate cryogen-free. When ordered with a low-vibration option, the system offers best-in-class vibration levels for applications in which Lake Shore’s ST-500 cryostat is used.
Also at IMS, Lake Shore will be available to answer questions about its cryogenic measurement and control products, including cryogenic sensors, monitors, and controllers optimized for low-temperature research, as well as various other systems and instrumentation for early-stage electrical and magnetic material or device characterization.
