WG6 - Wide bandgap materials

SiC-LGAD sensors are promising candidates for timing and tracking detectors at future colliders. However, accurate position and time reconstruction can be challenging with analytical models when signal formation deviates from idealized assumptions. We present studies on SiC AC-LGAD using transformer-based machine learning models that process the full time-series waveform from the sensor...

WG6 - Wide bandgap materials

Advanced technologies such as nuclear fusion reactors, high-energy physics facilities, and space applications require radiation detectors capable of reliable operation under extreme conditions. In particular, the detection of 3.5 MeV alpha particles in future fusion devices like ITER demands high radiation hardness, thermal stability, and good spectrometric performance. 4H-SiC stands out due...

34. Research on Alpha Detection of Hydrogen-Boron Reaction Based on SiC Detector

WG6 - Wide bandgap materials

The hydrogen-boron fusion reaction is a promising candidate for future clean fusion energy. This work develops a silicon carbide (SiC) detector system for detecting alpha products from the hydrogen-boron reaction, focusing on response characteristics, energy resolution, and radiation hardness.
A single-channel SiC detector (5 mm × 5 mm with guard ring) was fabricated. Tests with an alpha...

47. Extraction of carrier trapping times in neutron-irradiated 4H-SiC detectors from TPA-TCT z-scan profile modelling

Cristian Quintana San Emeterio (Universidad de Cantabria and CSIC (ES))

WG5 - Characterization techniques - facilities

We present a method for extracting electron and hole trapping times in neutron-irradiated 4H-SiC radiation detectors from the Two-Photon Absorption Transient Current Technique (TPA-TCT) z-scan charge profiles. Three planar p-in-n diodes fabricated at IMB-CNM, comprising a pristine device and two irradiated to neutron-equivalent fluences of 4×10¹⁴ and 1×10¹⁵ n_eq cm⁻², were characterised at...
