First successfully accomplished application and results on LGAD/nLGAD detector performance in laser-driven proton-boron (p-B) fusion plasma diagnostics

Abstract High-intensity laser pulses used during laser-matter interaction generate intense bursts of X-rays together with energetic charged particles, whose detection is crucial during laser ion acceleration or laser-driven fusion experiments. Accurate time-of-flight (ToF) diagnostics in this environment require fast and radiation-tolerant detectors capable of operating under strong electromagnetic pulse (EMP) conditions. In this work, we investigate p-type and n-type Low Gain Avalanche...

Impact of the Guard Rings on Self-Induced Signal and Leakage Current in Trench-Isolated LowGain Avalanche Diodes

In this contribution, we explored the interplay of guard ring (GR) configuration and isolation structures, as well as irradiation effects, which all together create a rich landscape of phenomena such as self-induced signals (“ghosts”) in trench-isolated Low-Gain Avalanche Diodes (TI-LGADs). The ghost effect is related to the increased surface current due to presence of SiO2 trenches (and defects) in studied diodes, but it is also affected by interplay between the guard ring(s) and the n+ bias ring,...

Exploring the Interpad Gap Region in Ultra-Fast Silicon Detectors: Insights into Isolation Structure and Electric Field Effects on Charge Multiplication

We present an in-depth investigation of the interpad (IP) gap region in the ultra-fast silicon detector (UFSD) Type 10, utilizing a femtosecond laser beam and the transient current technique (TCT) as probing instruments. The sensor, fabricated in the trench-isolated TI-LGAD RD50 production batch at the FBK Foundry, enables a direct comparison between TI-LGAD and standard UFSD structures. This research aims to elucidate the isolation structure in the IP region and measure the IP distance between...
