摘要: 把4個直徑5cm的復合晶體探測器(NaI/BaF₂,NaI/BGO,NaI/CsI和NaI/NaI)用氣球載至36km高空,觀測了它們的本底水平。無論是在符合或反符合狀態工作,4個復合晶體探測器主晶體的積分計數率基本一致。NaI/BGO探測器的計數率微分譜低于NaI/CsI和NaI/NaI探測器的相應值;NaI/BaF₂探測器的符合計數率微分譜低于NaI/CsI和NaI/NaI,而反符合計數率微分譜不高于NaI/CsI和NaI/NaI的相應值。

Abstract: In the paper designed four complex detectors and observed their background counting rates in balloon space environment. The primary crystal is Nal(Tl) scintillator of each complex detector. Its veto crystal is BaF₂, BGO, CsI(Tl) and Nal (Tl) separately. The results shown that the integral background counting rates of four complex detectors in region of energy 30~350keV at altitu-de31~36km are near. There is no obvious difference each other on y background noise level in space environment. The differential counting rates of Nal/BGO and NaI/BaF₂ detectors are lower than Nal/CsI and Nal/Nal detectors.
