AI总结:

本文研究了采用180 nm CMOS工艺的TJ-Monopix2单片像素探测器的电荷收集与探测效率,通过低剂量n型硅注入改进工艺以提升抗辐射能力,并通过实验室测量和束流测试验证了未辐照模块的电学特性与击中探测效率。

摘要:

单片CMOS像素探测器已在高能粒子物理探测器领域成为具有竞争力的候选方案。通过利用商用工艺,此类探测器可实现大批量生产。基于180 nm Tower工艺,已设计出一系列原型,该工艺具有传感器材料耗尽和列漏极读出架构。最新迭代版本TJ-Monopix2具有一个2 cm x 2 cm的大矩阵,由512 x 512个像素组成,像素间距为33.04 um。小收集电极设计旨在实现低功耗和低噪声,而面向高能粒子探测器应用的抗辐射能力则需要额外关注。为达到对NIEL损伤具有10^15 1 MeV n_eq cm^-2水平的抗辐射能力,已对标准工艺进行了改进,在像素内添加了低剂量n型硅注入,以实现传感器体积的均匀耗尽。近期对未辐照模块进行了实验室测量和束流测试,以研究其电学特性和击中探测效率。

英文摘要:

Monolithic CMOS pixel detectors have emerged as competitive contenders in the field of high-energy particle physics detectors. By utilizing commercial processes they offer high-volume production of such detectors. A series of prototypes has been designed in a 180$\,$nm Tower process with depletion of the sensor material and a column-drain readout architecture. The latest iteration, TJ-Monopix2, features a large 2$\,$cm x 2$\,$cm matrix consisting of 512 x 512 pixels with 33.04$\,$um pitch. A small collection electrode design aims at low power consumption and low noise while the radiation tolerance for high-energy particle detector applications needs extra attention. With a goal to reach radiation tolerance to levels of $10^{15}\,1\,$MeV n$_\text{eq}\,$cm$^{-2}$ of NIEL damage a modification of the standard process has been implemented by adding a low-dosed n-type silicon implant across the pixel in order to allow for homogeneous depletion of the sensor volume. Recent lab measurements and beam tests were conducted for unirradiated modules to study electrical characteristics and hit detection efficiency.
