    automatic mode and manual mode
    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
    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
