    Low-Gain Avalanche Diodes (LGADs) with an active thickness of $\sim$50 $\mu$m have shown precise timing capabilities, achieving resolutions around 30 ps, as well as precise spatial resolution. As of now, their performance seem not to be affected by the radiation, at least up to fluences of 2.5$\times$10$^{15}$ 1 MeV n$_{eq}$/cm$^2$. In late 2022, FBK developed a batch of thin LGADs with...

    Low Gain Avalanche Detectors (LGADs) show outstanding precision timing performance for high-energy physics (HEP) particle detection and will be employed in detector upgrades for the High-Luminosity LHC. However, traditional p-type LGADs face limitations in detecting low-penetrating particles, such as soft X-rays and low-energy protons. To address this, n-type LGADs (nLGADs) have been...

    This contribution presents the design, production, and initial testing of newly developed 4H-SiC Low Gain Avalanche Detectors (LGADs). The evaluation includes performance metrics such as the internal gain layer’s efficiency in enhancing signal generation. Initial laboratory and Transient Current Technique (TCT) measurements provide insight into the device’s stability and response to the...

    Talk

    In collaboration with Fondazione Bruno Kessler, the Paul Scherrer Institute is developing Low-Gain Avalanche Diode (LGAD) sensors for soft X-ray science at synchrotrons and free electron lasers. While hybrid pixel detectors using standard silicon sensors are limited to photon energies above 1 keV due to quantum efficiency and signal-to-noise ratio constraints, LGAD technology extends their use...
