Summary
Closed-cycle cryostats, such as the Advanced Research Systems DE-202 model are commonly used in laboratories as they provide long-term, low-cost, low-maintenance operation. We will outline the assembly, testing processes, and benchmarking experiments associated with the setup of this instrumental accessory. Further, a technical manual was written for future students and faculty in undergraduate research. Assembly involved constructing a custom frame, and integrating vacuum, water, gas, and electrical systems. Testing confirmed the system did not leak gas. Thermal response was recorded during cooling and heating phases to verify functionality; a base temperature of 7.5 K was achieved in 65 minutes, surpassing the expected 9 K, and matching results from Ziegler et al[1]. The heater maintains temperatures within 0.2 K of the set value. Absorbance of an ITO coated glass slide was measured showing an increase with temperature. Suitable for optics and electrical conductivity measurements, this apparatus expands low-temperature research opportunities across physics, chemistry, and biology.
