Tharollo ea ho Fumana Mahlaseli a Nyutlelie
Ho sibolloa, ho beha leihlo, le ho khetholla lisebelisuoa tsa nyutlelie e tla ba phephetso ea bohlokoa lilemong tsena tse leshome.Sepheo sa rona ke ho fana ka tharollo e tšepahalang ka ho fetisisa bakeng sa lefats'e la ho sibolloa.
Mathata a ho Khetholla Mahlaseli a Nyutlelie:
Boholo ba lits'ebetso tsa ho bona mahlaseli a kotsi li ile tsa kopana le mathata a tšoanang ho kenyelletsa:
Seo Kingheng a ka fanang ka sona:
Kinheng e na le bokhoni ba tharollo ea letoto lohle le teng, Re ka fana ka Scintillator +PMT assembly SD module, Scintillator+PMT+DMCA solution, Scintillator+PMT+HV+preamplifier+Signal, Scintillator+SiPM detector, Scintillator +PD detector, CZT semiconductor bakeng sa ho lemoha mahlaseli.Re na le tharollo eohle bakeng sa indasteri ena ho kenyelletsa le boto ea PCB.
Ha re tsoa lefapheng la mahlale a bohlokoa, re ile ra tla le mokhoa o mocha oa ho lemoha mahlaseli.
Theknoloji ea rona ea sethala e etsa hore ho be le litharollo tse ngata tse ikhethang limmarakeng tse 'maloa, tse ipapisitseng le lisebelisoa tse latelang tsa mantlha:
NaI(Tl) detector:
KINHENG e fana ka litekanyo tsohle tsa letoto la lisebelisoa tsa scintillator tsa NaI(Tl) ts'ebelisong e fapaneng, mefuta ea rona e fumanehang ke likristale tse hlobotseng tsa Dia10mm ho Dia200mm tse fumanehang.FWHM e fapaneng: 7% -8.5% @Cs137 662Kev
Ntle le moo, re ka fana ka ts'ebeletso ea ho itlhophisa ka mefuta e fapaneng e bohale ea kristale ho kenyeletsoa Cylinder, cubic, qetellong hantle, lifensetere tse ka lehlakoreng le encapsulation.Lilemong tse mashome a seng makae tse fetileng, li-scintillator tsa NaI(Tl) ke lisebelisoa tsa ho lemoha mahlaseli a nyutlelie lefatšeng ka lebaka la FWHM ea eona e ntle, theko e tlaase ka ho fetisisa, botsitso jj.
Kinheng e boetse e fana ka ts'ebeletso ea kopano ea Crystal, ho kenyeletsoa Crystal+PMT+Housing,+ e sireletsang+ BNC kopano e le 'ngoe+HV+MCA.
CsI(Tl) detector:
CsI(Tl) scintillator e ntle bakeng sa ho ts'oara ka letsoho, mochine o nkehang habonolo.re ka fana ka boholo ba mefuta e fapaneng ea thepa ena.Li-cubic le cylinder Sharpe lia fumaneha.E holisitsoe ke mokhoa oa ho hola oa Czochralski, ho ts'oana, FWHM, tlhahiso ea leseli e betere ho feta Bridgman Temperature e fetolang kholo ea Technique.Mekhahlelo ea litekanyo e fumaneha 1×1×1mm, 1”×1”×1”, 3”×3”×3”, 3”×3”×12”, Dia10mm ho fihla ho Dia300mm.
FWHM e fapaneng: 6.5% -7.5% @Cs137 662Kev
Kinheng e boetse e fana ka mochini oa kopano ho kenyelletsa CsI(Tl)+TiO2 COATING+ SiPM KAPA PD.
CsI(Na) detector:
Boholo ba nako detector ea CsI(Na) e sebelisoa indastering ea Oli(MWD/LWD), ka lebaka la tlhahiso ea eona e phahameng ea khanya, theko e tlase, Dimension e fumanehang Dia2”, bolelele ba 300mm.
CLYC: Ce detector:
Bakeng sa tlhahlobo ea neutron, re ka fana ka CLYC:Ce ho fihlela litlhoko tsa bareki.Ka lebaka la isotope Li e na le bokhoni bo phahameng ba ho lemoha bakeng sa neutron.Dimension e teng ke Dia25mm.
FWHM: 5%max @Cs137 662Kev, Kapa mohloli oa 252CF.
GAGG: Ce detector:
Re ka fana ka Dia60x180mm GAGG ingot, ho latela ts'ebeliso e fapaneng, boholo bo hlophisitsoeng boa sebetsa.
