HTCAS-300AC Magnetic Susceptibility Measurement Instrument for High Temperature Superconducting Materials

HTCAS-300AC Magnetic Susceptibility Measurement Instrument for High Temperature Superconducting MaterialsMainly used for measuring the AC magnetization and superconducting transition temperature of high-temperature superconducting materials. This device includes a sealed vacuum chamber, compression refrigeration machine, vacuum pump, vacuum gauge, lock-in amplifier, temperature controller, computer, and coil winding. This instrument is capable of measuring and displaying the physical phenomenon of the resistance of superconducting thin films decreasing with temperature and repelling magnetic field lines passing through the temperature range of 50-300K. At the same time, the measuring instrument can measure the superconducting transition temperature by measuring the change in AC magnetization of superconductors. Further research and understanding of the fundamental physical properties of superconductivity * diamagnetism.

Product advantages:

1. The temperature can be controlled to rise or fall slowly as needed, and more data points can be measured within the transition temperature range to prevent the omission of important changes and reduce temperature hysteresis effects;

2. Use low-temperature vacuum thermal grease to fix the superconducting sample on the primary coil skeleton, ensuring better temperature transfer between the refrigeration machine and the superconducting sample;

3. Using computers to automatically save measurement data to ensure that measurement data is not lost in the event of a power outage accident;

4. It can display the real-time curve of the Xiaoyi Dayi signal measured by the lock-in amplifier as a function of temperature, making it easy to grasp the measurement situation in a timely manner. It is an efficient, accurate, and reliable new generation testing instrument.
