中微子工厂用环形磁化铁中微子探测器(MIND)
A Toroidal Magnetised Iron Neutrino Detector (MIND) for a Neutrino Factory
摘要:
中微子工厂在发现和测量中微子区的CP破坏方面具有无与伦比的物理范围。中微子工厂的远探测器必须具有良好的电荷识别能力、良好的背景抑制能力和较大的质量。一个优雅的解决方案是沿着MINOS的路线建造磁化铁中微子探测器(MIND),其中铁板提供环形磁场,闪烁体平面提供3D空间点。在这份报告中,一个中微子工厂的环形MIND模拟的现状进行了讨论,根据最近的测量大$θ_{13}$。使用10 GeV中微子工厂配置的响应和性能。结果表明,这种设置具有等效的$δ_{CP}$达到一个具有偶极场的MIND,并且对发现CP破坏超过$δ_{CP}$值的85%是敏感的。
英文摘要:
A neutrino factory has unparalleled physics reach for the discovery and measurement of CP violation in the neutrino sector. A far detector for a neutrino factory must have good charge identification with excellent background rejection and a large mass. An elegant solution is to construct a magnetized iron neutrino detector (MIND) along the lines of MINOS, where iron plates provide a toroidal magnetic field and scintillator planes provide 3D space points. In this report, the current status of a simulation of a toroidal MIND for a neutrino factory is discussed in light of the recent measurements of large $θ_{13}$. The response and performance using the 10 GeV neutrino factory configuration are presented. It is shown that this setup has equivalent $δ_{CP}$ reach to a MIND with a dipole field and is sensitive to the discovery of CP violation over 85% of the values of $δ_{CP}$.
