The irradiation area of this cryogenic irradiation system has a beam spot size of no more than 20 mm × 20 mm. The apparatus employs liquid nitrogen cooling, and during experiments the sample‑stage temperature can be continuously adjusted within the range of −165 °C to ambient temperature, with a temperature control accuracy better than ±1 °C. To date, online tests have been conducted at multiple set points; at 15 °C, 0 °C, and −30 °C, the temperature control accuracy is stably maintained at ±0.1 °C, while at −50 °C, −100 °C, and −150 °C, the corresponding accuracies are ±0.3 °C, ±0.5 °C, and ±1 °C, respectively.

The development of the cryogenic target‑chamber cold table represents a new endeavor by Zhongguang to expand into areas such as materials irradiation, aerospace‑device testing, and low‑energy nuclear astrophysics. Looking ahead, Zhongguang will continue to deepen its expertise in this field, steadily advancing its technological capabilities to provide more advanced, high‑precision equipment to an expanding array of platforms and enterprises.

In addition, the Congtical Technology thermal‑cold stage is widely applicable to research areas such as geological analysis, optoelectronic materials, piezoelectric materials, perovskites, single‑molecule conductance, shape‑memory alloys, cryogenic treatment, photocatalysis, biomedicine, and aerospace. It supports an extended temperature range from −196 °C to 1000 °C, and its miniature platform enables rapid thermal equilibration. Employing a single‑input, dual‑output temperature control strategy, it utilizes adaptive PID control to achieve high‑precision setpoint regulation and superior temperature‑tracking performance.
