Filed: 1980-06-02
Abstract: PURPOSE:To eliminate the occurrence of discharge spot and to prevent the disconnection of filament, by encapsulating a light emission tube, starting heat-responsive element and a heating filament contained in a container into an outer tube together with gas. CONSTITUTION:A light emission tube 10, bimetal switch 4 and a heating filament 5 are contained in an outer tube 7 for high pressure sodium lamp, while gas having pressure lower than 100 Torr is encapsulated for the purpose to suppress the surge voltage due to the operation of the bimetal switch 4.

Title: Ion source
Inventor: SHIMADA TADANORI
IPC: H01J3/04
Filed: 1982-05-04
Abstract: PURPOSE:To obtain an ion source of extremely simplified construction while keeping the performance as before such as ionization efficiency or the like by composing a baffle of two meshes and a cylindrical hollow column for suring a space of said meshes. CONSTITUTION:A baffle 3 is composed of two meshes 18 and a hollow column 19 so that potential inside of the baffle is supplied exclusively from a gap between the baffle 3 and ball pieces 5 on the upstream side because the baffle 3 does not transmit electrons 17 due to its maintained potential. On the other hand, the baffle 3 part transmits neutral atoms 17 having no chare. Accordingly, a servicing quantity of neutral atoms from an electron servicing part can be held small even in an ion source having a big required servicing quantity of the neutral atoms not less than 10cm in the ion diameter thus causing no drop of main plasma potential while being able to obtain the ionization efficiency as before besides requiring no new neutral atom servicing system or distributor and being able to constitute the ion source with extremely simplified construction as well as to remarkably reduce its weight when utilized as an ion engine for an artificial satelite.
