Scintillation Crystal
(Sub Surface Laser Engraving)
Scintillation-based detectors, vachishandisa pixelated inorganic crystal scintillators, variinoshandiswa zvakanyanya kuona particle uye nemwaranzi, kusanganisira mupositron emission tomography (PET) scanners.
Nekuwedzera maficha-anotungamira maficha kune kristaro, iyo spatial resolution ye detectorinogona kuvandudzwa kusvika pachiyero chemirimita, ichiwedzera kugadzirisa kwese kwetomograph.
Zvisinei, nzira yechinyakare yekuita pixelating mumuvirimakristasi ari amaitiro akaoma, anodhura, uye anoshanda nesimba. Uyezve, chikamu chekutakura uye kunzwa kwe detectorinogona kukanganiswanokuda kwenon-scintillating reflective materials inoshandiswa.

Subsurface Laser Engraving yeScintillation Crystal
Imwe nzira yekushandisa ndeyesubsurface laser engraving (SSLE) maitiroye scintillator makristasi.
Nekutarisa laser mukati mekristaro, kupisa kwakagadzirwainogona kugadzira inodzorwa pateni ye microcrackskutiita sezvimiro zvinoratidzira, kunyatsogadziramapikisi anotungamira chiedzapasina kudiwa kwekuparadzana kwenyama.
1. Hapana pixelation yemuviri yekristaro inodikanwa,kuderedza kuoma uye mari.
2. Unhu hwemaziso uye geometry yezvimiro zvinoratidzira zvinogona kuvakunyatsodzorwa, inogonesa dhizaini yeyakajairwa pixel maumbirwo uye saizi.
3. Readout uye detector architectureramba wakangofanana neyakajairwa pixelated arrays.
Laser Engraving Process (SSLE) yeScintillator Crystal
Iyo SSLE engraving process inosanganisiramatanho anotevera:
1. Magadzirirwo:

4. Ongororo Yemhedzisiro:
Kuongororwa kwekuita kwekristaro yakavezwa uchishandisa amufananidzo wemunda wemvurauyeGaussian yakakodzerakuongorora mhando yepixel uye kugadziriswa kwenzvimbo.

Thesubsurface laser engraving nziranokuti scintillator makristasi anopa akushandura nzirakune pixelation yezvinhu izvi.
Nekupa chaiyo kutonga pamusoro peiyo optical hunhu uye geometry yezviratidziro zvimiro, iyi nzirainogonesa kuvandudzwa kweiyo innovative detector architecturespamweyakawedzera kugadziriswa kwenzvimbo uye kuita, zvosepasinakudiwa kwekuoma uye kudhura kwemuviri pixelation.
