uidm256a-czt40 产品详情
产品概要the micro-idm compact gamma ray detector module comes with a room temperature cadmium-zinc-telluride (czt) semi-conductor sensor with 256 pixels, arranged in a 16×16 matrix. each pixel is connected to a channel with amplification and trigger circuitry implemented in application specific integrated circuits (asics).
the asic amplifies and samples the analog signal when the input signal is above a user programmable threshold. the trigger signal, the address of the triggered channel and the charge signal is then available at the at the output interface. the output self-resets after a predetermined time.
the uidm256a allows for gamma ray energy measurements up to 350 kev. the module has been measured to with a co-57 source and at room temperature. the co-57 photo-peak at 122 kev has 5.4 kev full-width-half-maximum (fwhm) energy resolution.
the modules can be arranged to create gamma ray cameras of different geometries. typical applications include arrays of uidm256 modules, creating a larger imaging array. the module has two m2 threaded holes for mounting. the module has two electrical connectors, which allows for mounting on a carrier board.
the detector modules are insensitive to magnetic fields and can be operated in vacuum/space.
the module is also available with 25.4 mm x 25.4 mm czt crystal: uidm256a-25.4, or without a crystal: uidm256a.
the uidm256 is also available in a 700 kev-charge range version: uidm256b-czt25.6
carrier boards for multiple uidm256 modules can be delivered, contact ideas for more information.
