In the drawing of FIG. 1, a vacuum and a mercury cathode generator is shown; FIG. 2- about modification.

In FIG. 1 and 2 designate: Aerated balloon, M-mercury cathode, auxiliary electrode and D-condensing chamber.

Littered with the help of an auxiliary electrode, K, the mercury arc, supported by the case of need by additional low-voltage electrically, forms a ward and emits a powerful stream of electrons, the path of which is indicated on the drawing by a paint. The mercury bunks, reaching the condensation chamber D by the cooled effluent, condense on

its walls. Residual gases are removed to cylinder A by suction on the principle of a Langmuir pump. So, usually the deteriorating vacuum gifts of mercury carry in this case the useful work of a pump that improves the vacuum. In the proposed vacuum generator, if necessary, provision is made for a foreball balloon, indicated in FIG. 1 by a dotted line.

In order to achieve the linearity of the electron flux of the above, the design of the vacuum generator is modified according to FIG. 2, In this design, a normal pump. Nangmuir also frees the anode area A. of the anode and grid from the existing gases. Mercury vapors of the cathode K streams instead of with a stream of electrons to penetrate the balloon A ,. filtered by condensation on the walls of condensing chamber J9, and the flow of electrons is directed to the anode.

The subject of the natent.

A modification of the vacuum generator described in Patent No. 14706, characterized in that, in order to use it as a mercury detector, in the upper part of the pump is welded an anode with an anode .4 without a grid.
