A mercury jet as gas target window for high current beams

A mercury vapour jet is used to seal a 1 cm 2 aperture between a gas volume (“target chamber”) and the beam-line system. The possible pressure differences and the leakage related to the different target gas pressures have been investigated. Pressure gradients from 10 1 to 10 −3 mbar and leakages of...

Summary:A mercury vapour jet is used to seal a 1 cm 2 aperture between a gas volume (“target chamber”) and the beam-line system. The possible pressure differences and the leakage related to the different target gas pressures have been investigated. Pressure gradients from 10 1 to 10 −3 mbar and leakages of less than 3×10 −3 mbar 1/s have been observed. The maximum target pressure was p T=36 mbar.
