Title: Mass-spectrometer apparatus
Inventor: SETO GIICHI
IPC: H01J37/317
Filed: 1979-03-19
Abstract: PURPOSE: To enable the degrees of damages and fouling in analytical tube by sputtering to be known without making periodical disassembly and inspection by disposing the mass analytical tube which is fixed with one end of a leaf spring at the most spattered portion in a guide liner.  
     CONSTITUTION: In this mass-spectrometer apparatus, one end of a leaf spring 2 is fixed to one end of a guide liner 1 and the other end 4 is welded to the portion where the liner 1 is particularly spattered. The leaf spring 2 having beforehand been formed to the radius of curvature smaller than the radius of curvature of an analytical tube 3 is mounted to the liner 1 and if the spatter of heavy ions continues for more than a fixed time, the liner 1 closes the tube 3 and automatically announces this to the operator. Namely, the tube 3 is spattered by ions of heavy mass mainly at the portion 4 therein. And when the portion 4 completely fusion-cuts owing to the spattering, the spring 2 perfectly closes the tube 3, as a result of which synchroscope and beam current are not normally displayed and therefore the operator is able to readily know the analysis failure.
