HGCAL

The Phase 2 CMS endcap calorimeter upgrade is an ambitious project from many points of view, including the engineering, the electronics, and the offline software. The ultimate goal is to produce and operate the first highly-granular calorimeter (HGCAL) with silicon and scintillator sections, that besides unprecedented spatial granularity will also provide precise energy and timing measurements – a 5D detector built for particle flow.

Starting from the experience of the CMS preshower and linear collider detector efforts, the HGCAL is a flagship and innovative detector that will in many ways trial the feasibility of detector technologies for future colliders.

We meet regularly to discuss on-going work and that work is then presented to the project.

There is a variety of activities in which CMG group members are contributing to, in close collaboration with other groups in the CERN CMS team as well as EP-DT and EP-ESE:

• Silicon sensor characterisation – irradiation, annealing, laser response, etc.
  • Staff: Marcello Mannelli, Jan Kieseler, Marc Dünser, Filip Moortgat.
  • Fellow: Matteo Defranchis.
• Electronics simulation – noise, front-end ASIC response, calibration, etc.
  • Staff: Pedro Silva.
  • Fellows: Kaya Tatar, Saranya Ghosh.
• Offline reconstruction – clustering and linking, heterogeneous computing, machine learning, etc.
  • Staff: Marco Rovere, Jan Kieseler, Felice Pantaleo, Erica Brondolin, Loukas Gouskos.
  • Fellows: Huilin Qu, Leonardo Cristella, Benedikt Maier, Nadya Chernyavskaya.
• Backend electronics – firmware, testing, mapping and load-balancing, etc.
  • Staff: André David, Pedro Silva.
  • Fellow: Laurent Forthomme.
• System and beam tests – software, data analysis, performance, etc.
  • Staff: André David, Clemens Lange.
  • Fellow: Saranya Ghosh.
