X-/β-ray cheeb tsam qhov ntom ntom ntsuas
Thaum cov hluav taws xob ua rau ntawm lithium roj teeb electrode, lub teeb hluav taws xob yuav raug nqus, cuam tshuam thiab tawg los ntawm electrode, uas ua rau muaj qee qhov attenuation ntawm cov hluav taws xob siv hluav taws xob tom qab cov hluav taws xob xa hluav taws xob thaum piv rau qhov teeb meem hluav taws xob, thiab lub foresaid attenuation ratio muaj qhov tsis zoo exponential kev sib raug zoo nrog cov electrode hnyav lossis qhov ntom ntom.
Cov ntsiab cai ntawm kev ntsuas
Precision "o"-hom scanning ncej:Kev ruaj ntseg zoo, max khiav ceev 24 m / min;
Tus kheej-tsim high-speed cov ntaub ntawv tau txais daim npav:Tau txais zaus 200k Hz;
Tib neeg-tshuab interface:Cov ntaub ntawv nplua nuj ( kab kab rov tav & ntsug qauv kab kos, daim ntawv qhia qhov hnyav ntawm lub sijhawm, daim ntawv qhia cov ntaub ntawv qub, thiab cov ntaub ntawv teev npe thiab lwm yam); cov neeg siv tuaj yeem txhais qhov screen layout raws li lawv xav tau; nws tau haum nrog cov txheej txheem kev sib txuas lus tseem ceeb thiab tuaj yeem paub qhov kaw-voj MES docking.
Cov yam ntxwv ntawm β-/X-ray nto density ntsuas ntsuas
| Ray hom | B-duab tshav ntom ntom ntsuas ntsuas - β-duab tshav yog electron beam | X-ray nto ntom ntom ntsuas ntsuas- X-ray yog electromagnetic yoj |
| Muaj feem xeem khoom | Cov khoom siv xeem: zoo & tsis zoo electrodes, tooj liab thiab txhuas foils | Cov khoom siv kuaj tau: zoo electrode cooper & aluminium foils, ceramic txheej rau separator |
| Ray yam ntxwv | Ntuj, ruaj khov, yooj yim rau kev khiav lag luam | Lub neej luv dua li β-duab tshav |
| Kev txheeb xyuas qhov sib txawv | Cov khoom siv cathode muaj qhov nqus coefficient sib npaug ntawm cov txhuas; thaum cov khoom siv anode muaj qhov nqus coefficient sib npaug ntawm cov tooj liab. | C-Cu absorption coefficient ntawm X-ray sib txawv heev thiab tsis zoo electrode ntsuas tsis tau. |
| Kev tswj hluav taws xob | Ntuj rays yog tswj los ntawm lub xeev. Kev kho hluav taws xob tiv thaiv hluav taws xob yuav tsum tau ua rau cov khoom siv tag nrho, thiab cov txheej txheem rau cov khoom siv hluav taws xob muaj qhov nyuaj. | Nws yuav luag tsis muaj hluav taws xob thiab yog li cov txheej txheem nyuaj tsis tas yuav tsum tau ua. |
Kev tiv thaiv hluav taws xob
Lub cim tshiab ntawm BetaRay density meter muab kev txhim kho kev nyab xeeb thiab yooj yim ntawm kev siv. Tom qab txhim kho cov nyhuv tiv thaiv hluav taws xob ntawm lub thawv ntawv thiab lub thawv ionization chamber thiab phasing tawm cov ntaub thaiv kab hlau rhuav, lub qhov rooj thiab lwm yam khoom loj, nws tseem ua raws li cov kev cai ntawm "GB18871-2002 - Cov Qauv Txheej Txheem ntawm Kev Tiv Thaiv Kev Tiv Thaiv lonizing Radiation thiab Kev Nyab Xeeb ntawm Radiation Sources", uas ua raws li ib txwm muaj. orientational koob tshuaj sib npaug ntawm 10 cm los ntawm txhua qhov chaw siv tau ntawm cov khoom siv tsis pub tshaj 1 1u5v / h.Tam sim no, nws tseem tuaj yeem siv lub sijhawm saib xyuas lub sijhawm tiag tiag thiab tsis siv neeg kos cim cim rau thaj chaw ntsuas yam tsis tau nqa lub qhov rooj ntawm cov khoom siv.
