How hot is China's artificial sun?

Could you please elaborate on the temperature reached by China's artificial sun? I'm intrigued to know just how hot this remarkable feat of engineering has managed to achieve. Is it comparable to the temperatures found in the CORE of our natural sun, or does it fall short by quite a margin? Additionally, I'm curious about the potential implications of such a high temperature for scientific research and technological advancements. Could you provide some insight into the significance of this achievement?
