Description
Silicon carbide (SiC) has emerged as a promising material for radiation detection in harsh environments, thanks to its wide bandgap, excellent radiation hardness, low leakage current, and suitability for high-temperature operation. These properties make SiC detectors attractive candidates for applications where conventional silicon detectors face significant limitations, such as fusion diagnostics or high-fluence experiments.
Within the framework of the SiCILIA project, a new generation of large-area, high-purity, thick p/n junction SiC detectors has been developed and extensively tested. These detectors have demonstrated excellent energy resolution, efficient particle identification, and resistance to radiation damage when exposed to particles with high fluence [1,2].
Building upon these results, and following previous efforts in monolithic telescope design [3], an integrated ΔE–E SiC detector telescope with an ultrathin ΔE stage (1 μm) and a thin E stage (10 μm) has been developed, aiming to exploit their capabilities for particle identification over a wide energy range.
In this contribution, the design, fabrication, and preliminary characterization results of the first prototypes of monolithic SiC telescopes will be presented. The detector has been characterized in terms of energy response, ΔE–E correlation, and signal processing optimization. In particular, shaping time studies were performed to mitigate interstage signal induction, improving energy resolution and ΔE–E correlation quality.
