A new experiment with an intense ~2 GeV neutrino beam at CERN SPS is proposed in order to definitely clarify the possible existence of additional neutrino states, as pointed out by neutrino calibration source experiments, reactor and accelerator experiments and measure the corresponding oscillation parameters. The experiment is based on two identical LAr-TPCs complemented by magnetized spectrometers detecting electron and muon neutrino events at Far and Near positions, 1600 m and 300 m from the proton target, respectively. The ICARUS T600 detector, the largest LAr-TPC ever built with a size of about 600 ton of imaging mass, now running in the LNGS underground laboratory, will be moved at the CERN Far position. An additional 1/4 of the T600 detector (T150) will be constructed and located in the Near position. Two large area spectrometers will be placed downstream of the two LAr-TPC detectors to perform charge identification and muon momentum measurements from sub-GeV to several GeV energy range, greatly complementing the physics capabilities. This experiment will offer remarkable discovery potentialities, collecting a very large number of unbiased events both in the neutrino and antineutrino channels, largely adequate to definitely settle the origin of the observed neutrino-related anomalies.

Scintillation light detection in the 6-m drift length ProtoDUNE Dual Phase liquid argon TPC
深地下中微子实验（DUNE）是长基线中微子振荡研究、中微子天体物理学和核子衰变研究的前沿实验。ProtoDUNE-Dual Phase（DP）是一个6x6 x6 m $^3$液氩时间投影室（LArTPC），于2019-2020年在CERN中微子平台上运行，作为DUNE远探测器的原型。在ProtoDUNE-DP中，LArTPC中宇宙μ子产生的闪烁和电致发光由放置在离电离轨道7米远的光电倍增管收集。在本文中，我们提出了性能的ProtoDUNE-DP光子探测系统，比较不同的波长移动技术和使用的氙掺杂LAr作为一个有前途的选择，为未来的大型LArTPC。闪烁光的产生和传播过程进行了分析，并与模拟进行了比较，提高了对液态氩特性的理解。

Characterization of tetrafluoropropene-based gas mixtures for the Resistive Plate Chambers of the ALICE muon spectrometer
欧洲核子研究中心大型强子对撞机ALICE实验的μ子识别系统是基于电阻板室（RPC）探测器。这些RPC在所谓的最大雪崩模式下使用由正乙烷（C $_{2}$ H $_{2}$ F $_{4}$）、六氟化硫（SF $_{6}$）和异丁烷（i-C $_{4}$ H $_{10}$）制成的气体混合物操作。所有这些成分都是温室气体：特别是前两种气体，由于欧洲联盟最近的条例，已经逐步停止生产，其成本正在逐步增加。因此，为了减少RPC操作对环境的影响，并且出于经济原因，寻找新的生态友好的气体混合物变得极其重要。由于类似的化学结构，氢氟烯烃似乎是替代C $_{2}$ H $_{2}$ F $_{4}$的合适的候选物，这是由于它们非常低的GWP，尤其是具有商品名HFO 1234 ze的正丙烯（C $_{3}$ H $_{2}$ F $_{4}$）。为了确定符合未来几年ALICE环境运行要求的环保气体混合物，已经建立了一个专门的实验装置，对有前途的气体混合物进行研发研究。测量已经进行了一个小尺寸的RPC配备了前端的电子设备，提供信号放大，开发ALICE操作在高亮度后，LHC长2002。本文讨论了添加CO $_{2}$的HFO 1234 ze基混合物，以及i-C $_{4}$ H $_{10}$和SF $_{6}$在这种混合物中作为猝灭剂的作用。

GigaTracKer（GTK）是CERN NA 62实验的光束光谱仪。该探测器具有具有挑战性的设计规格，特别是峰值粒子通量高达2.0 MHz/mm $^2$，单次命中时间分辨率小于200 ps，每个跟踪平面的材料预算为0.5% X $_0$。为了满足这些要求，特别是在硅混合时间戳像素技术和微通道冷却领域采用了新技术。本文介绍了检测器的设计和实现的性能报告。
