PILATUS (detector)
PILATUS bụ aha nke usoro Iwu nchọpụta x-ray nke Ụjọ ọrụ Paul Scherrer Institute mepụtara na Swiss Light Source ma melite ma zụọ ahịa site na DECTRIS. Ndị nchọpụta PILATUS dabeere na teknụzụ ịgụta photon (HPC), nke a na- X-rays ka ọ bụrụ akara eletrik site na mmetụta fotoelectric na semiconductor sensor layer - ma ọ bụ silicon ma ọ bụ cadmium telluride - nke nwere nnukwu voltaji. An'okpuru nnukwu voltaji ele anya. A na-agụ akara ọkụ eletrik ozugbo site na usoro mkpụrụ ndụ dị na ASIC jikọtara na ihe mmetụta. Mkpụrụ ndụ ọ bụla—ma ọ bụ pikselụ—bụ ihe nchọta zuru oke n'onwe ya, nke nwere mgbamu, ịkpa oke na sekit counter. Nke a ga-ekwe omume maka teknụzụ sekit agbakwunyere CMOS nke oge a.
Nchọpụta kpọmkwem nke otu foton na mkpebi ziri ezi nke ịgbasa na ike dị iche iche dị iche iche na-eme ka ndị nchọpụta PILATUS ghọọ ọkọlọtọ na ọtụtụ synchrotron beamlines na-eji maka ọtụtụ ngwa X-ray dị iche iche, gụnyere: obere akụkụ. ịgbasa, ịgbasa na-ejikọta ọnụ, X-ray powder diffraction na spectroscopy
Akụkọ ihe mere eme[dezie | dezie ebe o si]
E mepụtara ihe nchọpụta PILATUS mbụ buru ibu na PSI na 2003 dị ka ọrụ sitere na mmepe nke ihe nchọpụta pixel maka nnwale CMS na CERN. [1] ghọrọ ihe nchọpụta HPC mbụ a ga-eji mee ihe n'ọtụtụ ebe na synchrotron beamlines gburugburu ụwa.
[2] nke abụọ nke PILATUS2 nọchitere anya nnukwu mmelite teknụzụ, na-egosi nha pixel nke 172 × 172μm, omimi nke 20 bits na nhazi na-anabata radiation, dị mkpa maka ịrụ ọrụ na ụzarị X-ray siri ike na synchrotrons. N'afọ 2006, DECTRIS rere PILATUS2. Ubi nke protein crystallography ritere uru ngwa ngwa site na obere oge ọgụgụ na mkpọtụ na-enweghị mgbaàmà nke ihe nchọpụta, ebe ọ bụ na ọ belatara oge achọrọ iji chịkọta data. [citation needed]
Ọgbọ nke atọ PILATUS3, nke e webatara na 2012, gosipụtara teknụzụ retrigger ozugbo, [3] nke na-enye ohere maka ọnụ ọgụgụ photon dị elu karịa ndị bu ya ụzọ.
