This site is investigated about heat.
Now,I am inquiring about the extent of the temperature of the temperature measuring device used in the space. I say simply,,,I research that if the machine is what temperature,work normally,and inquire how to make the machine can work normally. And so on,I inquire how to make the crystal of Xe(Xenon one of the element). That is,I am inquiring the method of control heat.
It is a graduate school which I actually began to study this field. Then I began to study "heat".
All the substances have thermal noise. I cool the circuit of the precise electronic circuit to reduced thermal noise as much as possible because it becomes the obstacle of a circuit. And I inquired how to reduce thermal noise of circuit of the machine in order to achieve the performance.On the land,we can cool by liquid nitrogen,but in space we cannot, so I inquired about it.
The more temperature of an electron is high,the more it moves quickly. So, thermal noise is the electric noise which occurs by it. The thermal noise becomes obstructive.
