超NEMO是一个双β衰变实验,它将使用最近完成的NEMO-3实验中使用的成功的跟踪器-量热计技术。超NEMO将实施100公斤双β衰变同位素,对无中微子双β衰变(0νββ)半衰期的灵敏度约为1026年,相当于50-100 MeV的马约拉纳中微子质量。超近地磁场探测器开发计划的主要目标和挑战之一是使用由连接到光电倍增管的大容量塑料闪烁器块组成的量热计,达到能量分辨率ΔE/E,约为3%/E(MeV)σ,或7%/E(MeV)半高宽。我们描述了SuperNEMO量热计的研发计划和最终设计,它已经达到了这一具有挑战性的目标。
SuperNEMO is a double-β decay experiment, which will employ the successful tracker–calorimeter technique used in the recently completed NEMO-3 experiment. SuperNEMO will implement 100 kg of double-β decay isotope, reaching a sensitivity to the neutrinoless double-β decay (0 ν β β) half-life of the order of 1 0 26 yr, corresponding to a Majorana neutrino mass of 50–100 meV. One of the main goals and challenges of the SuperNEMO detector development programme has been to reach a calorimeter energy resolution, Δ E∕ E, around 3%∕ E (MeV) σ, or 7%∕ E (MeV) FWHM (full width at half maximum), using a calorimeter composed of large volume plastic scintillator blocks coupled to photomultiplier tubes. We describe the R&D programme and the final design of the SuperNEMO calorimeter that has met this challenging goal.
