The High-Luminosity phase of the LHC (HL-LHC) will bring an increase in the instantaneous luminosity of the present accelerator by a factor of 7.5, leading up to 200 interactions per bunch crossing. This extreme pile-up environment will be a challenge for the track reconstruction performance of ATLAS, particularly in the forward region. To address this, the High-Granularity Timing Detector...

IMB-CNM has been a main actor in the development of Low Gain Avalanche Detectors since the initial device conception, more than a decade ago. One of the challenges for LGAD is the deterioration of the gain and timing resolution after radiation damage due to the acceptor removal mechanism. A well-established solution to increase radiation tolerance is carbon co-doping in the gain layer.

Oral

Low-Gain Avalanche Diodes (LGADs) provide excellent timing resolution on the order of 20 ps and are strong candidates for several collider experiments, both as 4D tracking detectors and as timing layers for particle identification. LGADs with capacitively coupled electrodes (AC-LGADs) achieve highly uniform gain and electric fields, enabling fine pixelation without dead regions. These features...

The realization of 4D tracking with simultaneous micrometer spatial and picosecond temporal resolution relies not only on sensor technology but also on a precise understanding and calibration of the readout electronics. While Trench-Isolated Low-Gain Avalanche Detectors (TI-LGADs) offer the necessary segmentation and intrinsic gain, this high level of segmentation necessitates a dedicated...
