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.
