An arrangement for providing a liquid metal jet in a vacuum environment comprising:
- a vacuum chamber;
- a nozzle arranged to provide said liquid metal jet;
- a jet receiver comprised within said vacuum chamber and arranged to receive liquid metal from said liquid metal jet;
- a first electromagnetic pump section comprising a first inlet and a first outlet, said first inlet having a first diameter;
- a second electromagnetic pump section comprising a second inlet and a second outlet, and a pumping conduit connecting said second inlet to said second outlet, said pumping conduit having a second diameter;
- wherein said first outlet is arranged to provide liquid metal to said second inlet;
- characterized in that said first diameter is at least 1.8 times as large as said second diameter.
A method for providing a liquid metal jet in a vacuum environment, comprising:
- collecting liquid metal in a receiver, said receiver being located in a vacuum chamber;
- pumping, using a first electromagnetic pump section, the liquid metal from the receiver to a second electromagnetic pump section;
- and
- pumping, using said second electromagnetic pump section, the liquid metal to a nozzle for generating a liquid metal jet;
- wherein said first electromagnetic pump section comprises a first inlet and a first outlet, said first inlet having a first diameter, and wherein said second electromagnetic pump section comprises a second inlet and a second outlet, and a pumping conduit connecting said second inlet to said second outlet, said pumping conduit having a second diameter,
- characterized in that said first diameter is at least 1.8 times as large as said second diameter.
