Chapter 1: Introduction
1.1 General
This chapter serves as a brief introduction to the components that make up a com-
plete testing environment with the Model CRX-6.5K station at the core of that sys-
tem. Also covered is a brief description of the testing environment and the types of
applications for the probe station.

1.2 Product
Description
Designed for versatility and high performance, the Lake Shore Model CRX-6.5K is our
premium cryogen-free closed cycle refrigerant probe station. This system is the solu-
tion for those looking for the convenience of cryogen-free operation and the excep-
tional measurement performance of a Lake Shore product. Using a self-contained
closed cycle refrigerator (CCR), the station will cool down to cryogenic temperatures
unassisted, eliminating the need for monitoring by the researcher. Various options
and configurations on the Model CRX-6.5K enable the researcher to conduct exacting,
challenging test measurements. The Model CRX-6.5K provides Lake Shore’s best low-
temperature cryogen-free performance, with configurations enabling sample tem-
peratures as low as 10 K. Multiple temperature sensors throughout the station
ensure accurate, repeated measurements.
The 2-stage CCR allows the sample to be maintained at elevated temperature during
cool down, reducing the potential for condensation, a critical requirement for mea-
suring organic materials. The Model CRX-6.5K is designed to accommodate wafers as
large as 51 mm (2 in) diameter.
