The BTL (Barrel Timing Layer) project is an additional layer that will be added to CMS for the high luminosity phase of the LHC. BTL is half of the MTD project (Minimum Ionizing Particle Timing Detector) which will allow for higher-resolution event reconstruction.
Currently, the following prototypes have been manufactured at ldeaSquare:
A proposed detector to be placed next to the FASER experiment in the LHC. The main component of FASERCal is the "3DCal" that will allow 3D track reconstruction of particles. Current prototypes are being developed at ETH for these 3DCal modules.
The 1st NGT Hackathon, held at CERN IdeaSquare from 7–11 April 2025, brought together more than 40 students and researchers from across the Next Generation Triggers (NGT) collaboration and 15 other institutes.
