高空间分辨率的像素传感器是未来环形正负电子对撞机CEPC顶点探测器的核心技术。为了在r(phi)平面达到5微米的次级顶点重建精度(impact parameter resolution),要求像素传感器本身的空间分辨率达到3微米。在低功耗和快速读出的设计约束下,采用Binary读出的像素pitch需要缩小到16~18微米才有可能满足高空间分辨率的要求。但是每个像素的模拟前端和数字逻辑电路所需的版图面积限制了像素pitch从目前主流的25~30微米进一步缩小。最新的3D-SOI技术在常规200nm SOI像素传感器的基础上,增加了垂直堆叠的upper电路层和高密度微球(micro-bump)阵列连接。这为保持像素电路功能的前提下,缩小像素pitch提供了技术条件。

硅探测器的抗辐照研究是高能物理实验中的一个很重要的课题。基于外延层的硅传感器将是未来高能物理探测器的一个重要候选技术,然而其辐照损伤机理并未像高阻硅衬底传感器那样已被深入研究。本研究将对基于外延层的肖特基管进行各项测试,提取出IV、CV特性曲线以及电荷收集效率等参数在辐照前与不同剂量辐照后的变化,以建立基于外延层硅传感器的辐照损伤模型,适用中子辐照通量最高可至$10^{16}\ n_{eq}/cm^{2}$。本报告将对此研究的阶段性结果进行介绍。

The Upgrade of the Large Hadron Collider to the High Luminosity LHC (HL-LHC) is scheduled to start around 2028 and will result in the delivery of ten times more integrated luminosity to the experiments. To withstand the much harsher radiation and occupancy conditions of the HL-LHC, the inner tracker of the ATLAS detector must be redesigned and rebuilt completely. The design of the ATLAS...

AMS自2011年开始在国际空间站上运行,迄今已在暗物质和反物质寻找、宇宙线研究取得重大成果,发现了许多不能被现有理论解释的新现象。美国白宫已于2021年12月31日宣布国际空间站将运行到2030年,并计划运行AMS直到国际空间站使命结束。为进一步提高AMS科学产出,理解已发现的新现象,特别是宇宙线正电子、反质子和高电荷原子核能谱的精确测量,更好地发挥在反物质等探索研究方面独到的优势,AMS实验计划于近期开始进行探测器升级,安装由两层共8平方米的硅微条探测器组成的Layer0硅径迹室。

Neutron Transmutation Doped Germanium have a very uniform distribution of dopants and can work as thermistor at ultra-low (10 mK) temperature when using Bolometric detection technique. NTD-Ge have played a critical role in many rare events searching experiments. We produced a batch of NTD-Ge samples by thermal neutron irradiation and fabricated several NTD-Ge thermistors. We did some...

The HL-LHC will run with 5 times higher instantaneous luminosity than the LHC. Severe pileup effect significantly degrades the physics sensitivities. MIP timing detector (MTD) is designed to provide precise measurement of the timing of MIPs to the level of 30 ps, and can bring remarkable identification performance of pileup vertices, which keeps the HL-LHC physics programs attractive. This...
