Daly detector

Ihe nchọpụta Daly bụ ihe nchọpụta gas-phase ion nke nwere "ọnụ ụzọ mbata" ígwè, scintillator (ihe nchọpụta phosphorus) na photomultiplier. A gụrụ ya aha onye mepụtara ya bụ Norman Richard Daly. A na-ejikarị ihe nchọpụta Daly eme ihe na mass spectrometers.

Ụkpụrụ nke ịrụ ọrụ

Ions nke kụrụ aka n'ọnụ ụzọ na-ahapụ electrons nke abụọ. Voltaji dị elu (ihe dị ka -20000 V) n'etiti ọnụ ụzọ na scintillator na-eme ka eletrọn dị ngwa na ihuenyo phosphor, ebe a na-atụgharị ha ka ọ bụrụ foto. A na-achọpụta foton ndị a site na fotomultiplier.

Uru nke onye nchọpụta Daly bụ na enwere ike kewapụ fotomultiplier site na windo, nke na-ahapụ foton site na oghere dị elu nke igwe spectrometer, si otú a na-egbochi mmetọ ọzọ nke nwere ike ime na ịgbatị ogologo ndụ nke onye nchọpụta ahụ. The Daly detector na-enye ohere a elu osooso mgbe ubi-free mpaghara nke a oge na-efefe mass spectrometer ụgbọ elu ụgbọ elu, nke nwere ike imeziwanye uche maka ion arọ.
