Lake Shore Cryotronics will be at next week’s International Microwave Symposium (IMS) in San Francisco to discuss cryogenic probe stations, cryostats, and other products optimized for high-frequency device research conducted at low temperatures.
On display in Booth #511 will be the tabletop TTPX probe station configured with 40-GHz arms and GSG-style 40-GHz probes for on-wafer measurements performed under vacuum. This setup, suitable for electrically probing full and partial wafers up to 51 mm (2 in) in diameter, is designed to ensure optimal RF/microwave measurement performance when characterizing devices as a function of variable temperatures.
Lake Shore offers cryogenic probe stations for probing at temperatures as low as 1.6 K as well as cryogen-free versions, such as the high-performance CRX-4K. This premium closed-cycle cryocooler-based station 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 are probe stations with integrated magnetic field, load-lock assembly, high-temperature (675 K), high-vacuum (10‑7 Torr), 360° sample stage rotation, and backside optical access options.
Also at IMS, the company will be discussing its industry-leading cryogenic measurement and control products and Environment by Janis cryostats optimized for microwave/RF research. Models are available with low-loss RF and microwave coaxial cabling and feedthroughs, enabling easy integration into high-frequency applications, as well as in ultra-high-vacuum and low-vibration versions with optical access options.
LHe/LN2 and cryogen-free cryostats can be ordered, and at IMS, Lake Shore will have its closed-cycle CCS-100 optical cryostat on display. This cryogen-free model provides <4 to 325 K cooling without using LHe.
However, for researchers who prefer using continuous flow cryostats for their research, Lake Shore representatives will be available to discuss how Lake Shore’s new Infinite Helium recirculating gas cooler system can be used to make their LHe cryostats operate cryogen‑free. Plus, because the system is fully automated — with no manual valves to adjust — it offers easy operation and ensures consistent and optimal cooling performance.
