Abstract
The ALICE Collaboration has submitted a proposal for a new exper- imental apparatus - ALICE 3 - built with state-of-the-art silicon technologies, to be installed at the Interaction Point 2 of the Large Hadron Collider (LHC) during Long Shutdown 4, in preparation for Run 5 (2035). In particular, for the Time-of-Flight (TOF) system, which plays a fundamental role in particle identification, a time resolution of 20 ps is required. Several silicon technologies are under investigation for this purpose, and among them, Low Gain Avalanche Detectors (LGADs) have garnered particular interest. The increasingly stringent demands for time resolution by future experiments have spurred an intense R&D campaign aimed at further im- proving their already excellent performance in terms of timing. Current studies have demonstrated the potential of a thinner LGAD design capable of achieving values very close to the requirements of ALICE 3. In this paper, the results obtained with the first prototypes of very thin FBK LGADs (25 and 35 μm) will be reported. Moreover, the innovative concept of the double-LGAD will be presented and beam test results on three different thicknesses, 25, 35 and 50 μm, will be shown. The results on double-LGAD demonstrated the expected enhancement of input charge for electronics while maintaining a time resolution comparable to or even better than a standard LGAD.
