Apparatus for forming an electron beam sheet. |
摘要 |
<p>Apparatus for forming an electron beam sheet includes a cathode member 5 having a slot 6 in a front surface thereof, a grid electrode 4 and the anode 1 of a thyratron. When it is desired to trigger the thyratron into conduction, a suitably large potential difference is applied between the cathode member 5 and the grid 4, resulting in a electron beam sheet being produced extensive of a slot 6 formed in the front surface of the cathode member 5. This produces ionisation and a main discharge current is established between the main anode 1 and cathode 2 of the thyratron.</p> |
