Lake Shore Cryotronics will be at next week's Applied Superconductivity Conference (ASC) exhibition in Honolulu, discussing cryogenic control and monitoring solutions as well as platforms for characterizing superconducting materials.

On display in Booth 215 will be 240 Series 2- and 8-input sensor modules, which provide a precise, convenient way to remotely monitor cryogenic sensors in superconducting particle accelerators and other applications employing distributed PLC-based control. The modules can be easily networked to PLCs from Siemens, Rockwell Automation, and others to simplify communications in PROFIBUS applications and feature circuitry that supports cable runs up to 300 m (984 ft) between them and the sensors. Because temperature values are communicated directly to the PLC master device, there is no need to use additional analog conversion equipment or complex PLC programming to generate values.

Also on display: the company’s new MeasureReady™ M81-SSM synchronous source measure system, which integrates from 1 to 3 source and measure channels into a highly synchronized and easy-to-use test system for precision characterization of multi-pin electronic materials. At ASC, Lake Shore will be demonstrating the very low-resistance measurement capabilities of the system, with its balanced current source (BCS-10) module and voltage measure (VM-10) module wired to a copper bar. This four-wire setup will show how the system utilizes very low DC and AC currents and lock-in detection, as well as noise rejection for highly sensitive material and device measurements. The system also simplifies wiring and control and saves test time with one instrument compared with a conventional, multi-instrument setup.

Additionally, Lake Shore representatives will be available to discuss:

• The company’s full range of cryogenic temperature control and monitoring instruments, including the Model 372 AC resistance bridge/controller, which is optimized for low-impedance superconducting material measurements (the compact Model 335 controller will be on display at ASC)
• LHe, LN₂, and cryogen-free cryostats and other environment by Janis cooling solutions optimized for superconducting experiments (the VNF-100 optical cryostat will be on display)
• Cryogenic sensors, including Cernox^® RTDs, which are ideal for monitoring superconducting magnet temperatures
• Cryogenic probe stations for on-wafer DC, RF, or microwave measurements of superconducting materials/devices at temperatures as low as 1.6 K and in fields to more than 2 T under vacuum
• Magnetic measurement and control instruments, as well as Hall magnetic sensors
