Lake Shore Cryotronics will be showcasing a wide range of material/device characterization and cryogenic cooling and control products at next week’s APS Global Physics Summit in Denver.  

For researchers interested in the latest technology for low-level measurements, the company will be demoing in Booth 1820 the use of its M81-SSM synchronous source measure system with SMU-10 modules in a TTPX cryogenic probe station. As part of a new offering, customers who order a cryogenic probe station with triaxial arms will now get an M81-SSM instrument plus SMU-10 modules at no extra cost.  

Featuring an innovative architecture for coordinating measurements from DC to 100 kHz, the M81-SSM is a system purpose-built for the demands of material characterization where sensitivity, synchronization, and low noise are not optional. It replaces an entire measurement rack with one synchronized, low-noise system. 

The SMU-10 module, which uniquely offers both DC and AC capabilities and an integrated lock-in, supports measurements with nanovolt and femtoamp precision. It delivers world-class DC accuracy for precise I-V characterization and the AC sensitivity of dedicated lock-in amplifiers — all in the familiar four-quadrant SMU format. In addition, its very low DC 10-MHz source noise avoids disturbing sensitive devices when used to characterize at He-4 temperatures, such as in a cryogenic probe station.

Also for attendees interested in material characterization, on display will be:

• The FastHall™ Station, a high-precision tabletop Hall measurement system that uses patented FastHall technology as provided by the included M91 FastHall controller (also shown: an insert for easily integrating the M91 into a Quantum Design PPMS^®)
• The fully integrated CryoComplete system, which includes M81-SSM instrumentation, a LN₂ cryostat, cryogenic controller, and software for 77 K to 500 K experiments
• A miniaturized replica of the electromagnet-based MagRS system, showing how its various options allow for VSM, Hall effect, and other measurements

Also on display in Lake Shore’s booth:

• A demo version of the fully automated Infinite Helium™ recirculating gas cooler system, which makes a liquid helium cryostat cryogen-free; a winner of a 2025 R&D 100 Award, the system can now be ordered with an option for synchrotron or beamline applications and a low-vibration option for sensitive microscopy applications in which an ST-500 cryostat is used 
• The new 346 cryogenic temperature controller, featuring 300 mK to 1,505 K control, 10 sensor inputs expandable to 26 inputs with option cards, and 4 PID-controlled 100 W heater outputs (400 W total) for rapid warm-up
• Cernox^®, ULT Rox™, platinum, and other cryogenic temperature sensors
• A closed-cycle CCS-100 optical cryostat for <4 K to 800 K cryogen-free cooling 

In addition, representatives will be available to discuss the benefits of Lake Shore’s:

• New CryoComplete Mössbauer system, which includes everything needed (a cryostat, temperature controller, high-performance spectrometer, and software) to perform precise Mössbauer spectroscopy measurements at cryogenic temperatures 
• Full range of cryogenic probe stations for performing on-wafer measurements at temperatures as low as 1.6 K and in fields as high as 2.5 T under vacuum
• Other temperature instruments, including the Model 372 AC resistance bridge for ultra-low temperature control and 240 Series input modules for precision remote monitoring of sensors in large-scale applications
• Magnetic test and measurement instruments and Hall sensors

Separate from the exhibition, on Friday at 2 p.m., Matthew Grayson of Northwestern Univ. will present on "Simultaneous Measurement of Carrier Density, Mobility, and Their Transients with Four Electrical Contacts: The Frequency-Multiplexed Hall Effect Method" (MAR-Z19 session). This research, authored by Lake Shore's David Daughton and other researchers from Northwestern as well as ETH Zurich, references the use of the M81-SSM for measurements.
