Claim 1
Independent Claim
203 words
A DEVICE FOR ANALYZING A GAS WHICH COMPRISES MEANS FORMING A COLLIMATED BEAM OF GAS PARTICLES WITHIN A VACUUM SYSTEM, MEANS DISPOSED IN THE PATH OF TRAVEL OF THE COLLIMATED BEAM OF PARTICLES FOR EFFECTING THE MODULATON THEREOF AT A PRESELECTED FREQUENCY, A MASS ANALYZER DISPOSED ADJACENT SAID MODULATING MEANS IN THE DIRECTION OF TRAVEL OF SAID BEAM, MEANS LOCATED ADJACENT THE ENTRANCE OF SAID MASS ANALYZER FOR EFFECTING THE IONIZATION OF AT LEAST A PORTION OF SAID COLLIMATED BEAM WITHOUT SUBSTANTIAL DIVERSION OF SAID BEAM SO THAT SAID PARTIALLY IONIZED BEAM TRAVELS DIRECTLY INTO SAID MASS ANALYZER, DETECTING MEANS MOUNTED ADJACENT THE EXIT OF SAID MASS ANALYZER FOR PRODUCING A MODULATED OUTPUT SIGNAL HAVING A FREQUENCY CORRESPONDING TO THE PRESELECTED FREQUENCY AT WHICH SAID BEAM IS MODULATED BY SAID BEAM MODULATING MEANS, SAID IONIZING MEANS AND SAID MASS ANALYZER PROVIDING A SUBSTANTIALLY UNIMPEDED PATH FOR THE PASSAGE OF THE UNIONIZED PORTION OF SAID COLLIMATED BEAM IN ORDER THAT PARTICLES IN THE BEAM NOT BE SCATTERED AND COMBINE TO FORM NEW PARTICLES NOT IN THE ORIGINAL BEAM, AND MEANS RESPONSIVE TO THE OUTPUT SIGNAL FROM SAID DETECTING MEANS FOR PRODUCING OUTPUT INFORMATION RELATED TO THE CHARACTERISTICS OF SAID MODULATED BEAM OF GAS PARTICLES.
