Electron Collision Source of Vacuum Silver Plating Discharge Type

Nqus Nyiaj Pulsed Electron Collision Source

Lub pulsed electron kev sib tsoo qhov chaw muaj cov qauv yooj yim zoo ib yam li cov tsoos Nier qhov chaw. Nws nta lub zog ion tsis sib xws thiab zoo spatial tsom kom haum raws li qhov yuav tsum tau muaj ntawm lub sij hawm-ntawm-flight huab hwm coj spectrometers.

Kev txhim kho ion qhov chaw muaj cov yam ntxwv ntawm tsis muaj mem tes voltage siv rau daim phiaj tswj. Lub rhiab heev ntawm qhov nruam electron beam ion qhov chaw yog 300 lub sij hawm siab dua li ntawm cov pulsed electron beam ion qhov chaw, thiab lub zog daws teeb meem yog txhim kho.

Discharge type electron collision sources yuav muab faib ua ob hom: magnetic field discharge type electron collision sources thiab non-magnetic field discharge type electron collision sources. Muaj ntau hom plasma ion qhov chaw, tab sis xws li cov khoom tsis sib nqus tawm ion yog siv rau hauv cov khoom siv xws li accelerators, isotope separators, thiab lwm yam ion mass spectrometers. Xws li qhov loj-scale ion tsis tau siv nyob rau hauv lub tshuab nqus tsev spectrometers ntev, tab sis nyob rau hauv xyoo tas los no, cov ntaub ntawv tseem ceeb kuj qhia tau hais tias xws li ion qhov chaw kuj tsim nyog rau kev soj ntsuam ntawm lub tshuab nqus tsev vacuum gases.

Nqus Nyiaj Ion Cia Electron Collision Source

Qee cov ntaub ntawv muaj feem cuam tshuam tau qhia txog kev tshawb fawb txog kev xaiv peb-dimensional quadrupole ion ntxiab raws li ion qhov chaw ntawm quadrupole mass spectrometer. Ntawm lawv, muaj ob hom kev tshawb fawb ntsig txog ntawm ion qhov chaw, ib qho yog ua los ntawm stainless hlau los ntawm kev ua tiav, thiab lwm yam yog ua los ntawm tooj liab hlau mesh. Tsim los ntawm nias. Vim hais tias peb-dimensional quadrupole ion ntxiab muaj peev xwm khaws ions, lub sij hawm khaws cia ions nyob rau hauv lub ion qhov chaw tuaj yeem tswj tau los ntawm kev kho qhov zaus ntawm cov hluav taws xob rho tawm ntawm qhov kawg cap electrodes. Qhov rhiab heev ntawm hom ion qhov chaw no cuam tshuam los ntawm qhov rov ua dua ntawm cov mem tes zoo.
