SYSTEM TEST CASES

00001: Ensure complete emptying of air

Step Step description Expected result
precondition system is off  
Switch on the system turn on the pump 95% vacuum
Having a leak we found a leak in the anode, the cathode and the joint between the cathode and the pump hose  Seal the leakage places
Switch Off the system Turn Off the pump the pump stops pulling out the air
Silicon use Put silicon in places where air leaks Stop leakage and get 95% vacuum when we restart the pump.
Postcondition System is off  

 

00002: power supply

Step Step description Expected result
Precondition System is Off  
Switch On the system turn on the power supply (P1) Get continuous power (6 V)
Switch Off the system turn Off the power supply (P1) Continuous power stops
Postcondition System is Off  

 

 

00003: Get electrons

Step Step description Expected Result
Precondition System is Off  
Switch On the pump turn On the pump 95 % vacuum
Switch On the power supply Turn on the power supply Get continuous power (6 V)
Burning the Tungsten (or use a electron gun) Burn the Tungsten by supplying it with 6 V power

Get electrons around the Tungsten (the lamp will light)
Switch Off the power supply turn Off the power supply  the lamp will turn Off
Switch Off the pump turn Off the pump the pump stops pulling out the air
Postcondition System is Off  

 

 

00004:High voltage

Step Step description Expected Result
Precondition System is Off  
Switch On the system Turn On the HV  Get continuous power ( between 5 Kv and 60 Kv )
Switch Off the system Turn Off the HV  Continuous power stops
Postcondition System is Off  

 

00005: Acceleration of electrons

Step Step description Expected Result
Precondition System is Off  
Switch On the pump turn On the pump 95% vacuum
Switch On the power supply turn On the power supply Get continuous power (6 V)
Switch On the High Voltage Turn on the HV power supply Get continuous power ( between 5 Kv and 60 Kv )
electrons acceleration Connecting the high voltage to the anode and the cathode (while controlling the change of force until we see the passage of electrons and their acceleration) Electrons leaving the anode accelerate towards the cathode and collide with it
Switch Off the HV Turn off The HV power supply Electrons acceleration Stop
Switch Off the power supply turn Off the power supply the lamp will turn Off
Switch Off the pump turn Off the pump the pump stops pulling out the air
Postcondition System is Off
