Lake Shore Cryotronics introduces new cryogen-free probe stations
Model CRX-VF and Model CRX-EM-HF cryogen-free probe stations
Lake Shore Cryotronics is pleased to introduce the new Model CRX-VF and Model CRX-EM-HF cryogen-free probe stations. These two new platforms add vertical and horizontal field to Lake Shore’s growing family of closed cycle refrigerator (CCR) probe stations. The new CCR probe stations are ideal for non-destructive measurement of the electrical, magneto-transport, electro-optical, parametric, high-Z, DC, RF, and microwave properties of materials and test devices. Nanoscale electronics, quantum wires and dots, spintronic (TMR, GMR) devices, and semiconductors are typical materials measured.
The new probe stations are simple to operate and control temperature efficiently using two stage CCR cooling engines that cut ongoing usage costs by eliminating the challenges of sourcing and handling liquid cryogens. Cooling automation allows one-switch startup and unattended cool-down.  The CCR probe stations provide full temperature instrumentation for accurate temperature measurement, stable control and optimized warm up for sample exchange that translates to research productivity. Depending on probe station and configuration, temperature ranges span from 8 K to 500 K, providing excellent temperature stability (10 mK to 20 mK). The Model CRX-VF and CRX-EM-HF provide field strengths of 2.5 T and 0.6 T, respectively. Sample stage vibration is limited to less than 1 micron throughout the full-scale temperature range so as not to affect measurement performance.
These new cryogen-free models expand Lake Shore’s overall line of probe stations to nine distinct models. “With the increasing costs of liquid helium, and the growing difficulty in obtaining it, we see more customers deciding to invest in cryogen-free measurement systems,” says Rob Ellis, Vice President of Strategic Planning at Lake Shore. “Our globally-installed base of CCR probes stations is growing rapidly.” CCR probe stations also simplify processes and reduce scheduling conflicts related to operating with cryogens – personnel trained in cryogen transfers and monitoring of cryogen are no longer necessary.
Lake Shore representatives will be showcasing the new CCR probe stations at the American Physical Society’s March Meeting 2012, in booth 200, from February 27-March 2, 2012, at the Boston Convention & Exhibition Center Exhibit Hall, in Boston, Massachusetts.
