Recently, the low-temperature irradiation system developed by the 320kV low-energy heavy ion comprehensive research platform of the Institute of Modern Physics has successfully completed low-temperature testing. Congtical low-temperature target chamber cold stgae, as the low-temperature control module of the system, played an important role in this test.

The irradiation area of the low-temperature irradiation system is within 20mm x 20mm, and the device adopts liquid nitrogen cooling. During the experiment, the temperature of the sample area is continuously adjustable within the range of -165 ℃ - room temperature, and the temperature control accuracy is within ± 1 ℃. At present, multiple temperature points have been tested online, and the temperature control accuracy of 15 ℃, 0 ℃, and -30 ℃ can be stable at ± 0.1 ℃. The temperature control accuracy of -50 ℃, -100 ℃, and -150 ℃ are ± 0.3 ℃, ± 0.5 ℃, and ± 1 ℃, respectively.

In addition, the Congtical hot and cold stage can also be widely used in research fields such as geological analysis, optoelectronic materials, piezoelectric materials, perovskites, single-molecule conductivity, memory alloys, cryogenic treatment, photocatalysis, biomedicine, aerospace, etc. It can achieve high and low temperature extension (-196~1000 ℃), and its micro platform can quickly achieve temperature equilibrium. Adopting a single input dual output temperature control strategy, using adaptive PID to achieve high-precision temperature fixed-point control and high-level temperature following control.
