Lake Shore Cryotronics will be at next week’s CEC/ICMC conference in Reno, NV, providing an early look at the company’s Model 346 cryogenic controller and discussing the new, innovative Infinite Helium recirculating gas cooler system. 

A next-generation controller designed for rapid, precise temperature management, the Model 346 features four 100 W heater outputs that deliver a total of 400 W of power, allowing the system to warm up twice as fast. It also includes four low-power 1 W heater outputs, and with 10 standard inputs expandable up to 26 with option cards, the controller measures temperatures ranging from 300 mK to 1500 K.

The Infinite Helium, Lake Shore’s newest lab cooling solution, is an automated system that makes a LHe cryostat cryogen‑free. It innovatively circulates helium in a closed loop, enabling the cryostat to operate without the need for a LHe Dewar. Plus, because it is fully automated — no more adjusting valves and constantly having to keep an eye on cooldown and runtime operations — hands-on operation is reduced from hours to seconds. Samples can be exchanged easily without warming up the system, allowing for fast turnaround times.

Lake Shore representatives will also be answering questions about the company’s:

• Industry-leading Cernox^® RTD sensors, which provide fast thermal response time and excellent stability over a wide temperature range, even when exposed to magnetic fields or ionizing radiation
• ULT Rox™ RTD sensors with a 5 mK to 40 K temperature range; they are the sensors for use with dilution refrigerators with calibrations down to 5 mK when paired with the Model 372 AC resistance bridge
• Other cryogenic controllers, including the Model 336 for control down to 300 mK and the Model 350 for control down to 100 mK when used with appropriate sensors
• Monitoring instrumentation, including the 12-channel Model 224 monitor and 240 Series sensor input modules for sensor monitoring in large-scale, PLC-based applications 
• Environment by Janis LHe, LN₂, and cryogen-free cryostats (on display will be the closed-cycle, cryogen-free CCS-100 optical cryostat)

For attendees interested in low-temperature characterization platforms, Lake Shore will also be available to discuss:

• The all-in-one CryoComplete™ system for 77 K to 500 K material or device research, containing a MeasureReady™ M81-SSM synchronous source measure system, LN₂ cryostat, controller, and PC with MeasureLINK™ software
• Cryogenic probe stations for performing on-wafer DC, RF, or high-frequency measurements at temperatures as low as 1.6 K and in fields to as high as 5 T under vacuum
• The new electromagnet-based MagRS system, customizable for vibrating sample magnetometer (VSM), ferromagnetic resonance (FMR), Hall effect, and electron transport measurements, and available with low- and high-temperature options 

Also during CEC-ICMC, Scott Courts, Lake Shore Metrology Scientist IV, will present a poster at 9:15 a.m. on Tuesday on “Cernox Cryogenic Temperature Sensor Performance after High Level Neutron Irradiation.” This poster’s research, co-authored by Brian Courts, details the survivability and performance of three neutron-irradiated and tested Cernox sensor models as a function of temperature and total neutron fluence. 

And prior to the start of the exhibition, Dr. Courts will present a CSA short course on “Practical Cryogenic Thermometry and Instrumentation” on Sunday from 1 to 5 p.m. To register, visit the CSA short course registration page.
