摘要:

我们设计、生产并测试了RSD(阻性交流耦合硅探测器)器件,这是标准LGAD(低增益雪崩二极管)技术的一种演变,其中已实施了阻性n型注入和耦合介电层。第一个功能作为一个电阻片,冻结倍增的电荷,而第二个作为一个读出垫的电容耦合。我们成功地实现了具有挑战性的目标,即获得非常精细的间距(50、100和200 um),同时保持信号波形适合高时序和4D跟踪性能,就像标准的基于LGAD的器件一样。

英文摘要:

We designed, produced, and tested RSD (Resistive AC-Coupled Silicon Detectors) devices, an evolution of the standard LGAD (Low-Gain Avalanche Diode) technology where a resistive n-type implant and a coupling dielectric layer have been implemented. The first feature works as a resistive sheet, freezing the multiplied charges, while the second one acts as a capacitive coupling for readout pads. We succeeded in the challenging goal of obtaining very fine pitch (50, 100, and 200 um) while maintaining the signal waveforms suitable for high timing and 4D-tracking performances, as in the standard LGAD-based devices.
