Main pump	Molecular pump	FF250/1600G， pumping rate1600L/s
Main pump	Molecular pump	FF250/1600G， pumping rate1600L/s
High vacuum pumping line	Main pumping line	The vacuum pumping end uses a molecular pump with a diameter of 100mm to directly connect to ensure the high vacuum in the experiment. A plate valve is added in the middle of the diameter straight pipe.
Foreline pump	mechanical pump	pumping rate30m³/h
Foreline pump	mechanical pump	pumping rate30m³/h
Low vacuum pumping line	side pumping line	The ends of the flapper valve are added with a 16mm diameter thin tube bypass branch to prevent the pumping speed from affecting the direction of molecular diffusion in the initial vacuum, resulting in uneven material.
vacuum degree	Low vacuum pump exhaust rate	2x10^-2torr within 20min in main chamber
	High vacuum pump exhaust rate	5x10^-6torr within 20min in main chamber after turining on Molecular pump
	Pressure test	After reaching the ultimate vacuum (5x10^-6torr), close all valves, less than 2x10^-2torr after 30min
