00001: Ensure complete emptying of air

Step	Step description	Expected result	Result
precondition	system is off
Switch On the system	turn on the pump	95% vacuum	negative
Having a leak	Possibility of air leakage in places: welding-flanges-anode-cathode-tungsten-windows.	Seal the leakage places	positive
Switch Off the system	turn Off the pump	the pump stops pulling out the air	positive
Silicon use	Put silicon in places where air leaks	Stop leakage and get 95% vacuum when we restart the pump.	positive
Postcondition	System is off

Analysis of the test results:

In order to know the places of air leakage, we put water and soap on the surface of the device, and we compressed the air in the device;

When we find bubbles appearing, this indicates air leakage in this place.

What we have to do:

- we will re-weld in the previous welding places where there was leakage.

-we will change the seal at the flanges due to leakage.
