Ce: YAG - Yakakosha Scintillation Crystal

Ce: YAG yakakosha scintillation crystal ine yakanakisa scintillation performance. Iyo ine yakanyanya kupenya inoshanda uye yakafara optical pulse. Mukana wakakura ndewekuti iyo yepakati wavelength ye luminescence i550nm, inogona kunyatsobatanidzwa nemidziyo yekuona senge silicon photodiodes. Kuenzaniswa neCsI scintillation crystal, Ce: YAG scintillation crystal ine kukurumidza kuora nguva, uye Ce: YAG scintillation crystal haina deliquescence, yakakwirira tembiricha kuramba, uye yakagadzikana thermodynamic performance. Inonyanya kushandiswa mukuvheneka chidimbu chechiedza, alpha particle yekuona, gamma ray yekuona uye mamwe minda. Uye zvakare, inogona zvakare kushandiswa mumagetsi ekuona ekufungidzira (SEM), yakakwirira-resolution microscopic imaging fluorescent skrini uye mamwe minda. Nekuda kweiyo diki yekuparadzanisa coefficient yeCe ions muYAG matrix (inenge 0.1), zvakaoma kuisa maCe ions mumakristaro eYAG, uye kuoma kwekukura kwekristaro kunowedzera zvakanyanya nekuwedzera kwekristaro dhayamita.
Ce: YAG imwe kristaro inokurumidza-kuora scintillation zvinhu zvine yakanakisa mativi zvivakwa, ine yakakwira mwenje kubuda (20000 photons/MeV), kukurumidza kupenya kuora (~ 70ns), yakanakisa thermomechanical zvivakwa, uye inopenya peak wavelength (540nm) Inonyatso enderana neyakajeka wavelength yemwenje uye silicon inogamuchira yakajairwa wavelength yepd (PMT photo) pulse inosiyanisa gamma rays uye alpha particles, Ce: YAG yakakodzera kuona alpha particles, electrons uye beta rays, nezvimwewo. Yakanaka mechanical properties yezvimedu zvinochajiswa, kunyanya Ce: YAG single crystal, inoita kuti zvikwanisike kugadzirira mafirimu matete ane uwandu husingasviki 30um. Ce: YAG scintillation detectors anoshandiswa zvakanyanya muelectron microscopy, beta uye X-ray kuverenga, erekitironi uye X-ray imaging screens nemimwe minda.
