美國Amptek公司 XR-100CR X射線探測器
Amptek是一家成立于1977年的高科技公司，致力于設(shè)計(jì)并制造核檢測儀表，在該領(lǐng)域處于世界領(lǐng)先水平。公司產(chǎn)品廣泛用于人造衛(wèi)星、X射線和伽瑪射線的探測、實(shí)驗(yàn)室、分析儀以及工業(yè)上的便攜式檢測儀器。
公司建立之初是為現(xiàn)階段的空間儀表提供高性能、高穩(wěn)定性、體積小以及低功耗的儀器和部件。隨后，公司的混合前置放大器成為航天工業(yè)的配置標(biāo)準(zhǔn)，并在全球范圍內(nèi)用于地表衛(wèi)星和外層空間探測器。Amptek已經(jīng)開發(fā)出一系列產(chǎn)品如等離子分析器、電子離子探測器以及輻射監(jiān)控器等，這些產(chǎn)品被廣泛用于軍事、科研和商貿(mào)等領(lǐng)域。
Amptek is a high technology company and a recognized world leader in the design and manufacture of state-of-the-art nuclear instrumentation for the satellite, x-ray and gamma ray detection, laboratory, analytical, and portable instrumentation industries.

Background
Amptek was founded in 1977 by Alan C. Huber and John A. Pantazis to fulfill the needs of space instrumentation for off-the-shelf, high performance, high reliability, small size and low power dissipation instruments and components. Shortly thereafter, Amptek hybrid preamplifiers became the standard for the space industry as they were used worldwide by instrument makers in both Earth satellites and deep space probes. Numerous plasma analyzers, electron and ion detectors, and radiation monitors have been developed by Amptek and flown in both military, research, and commercial spacecraft.
