Hamamatsu Photonics advancing astrophysics

September 2019. Conseil européen pour la recherche nucléaire (CERN) and Hamamatsu Photonics signed a series of three contracts for the supply of silicon sensors for particle physics experiments in the Large Hadron Collider (LHC), Geneva August 23, 2019. These sensors are designed for detecting and tracking particles in experiments of ATLAS (A Toroidal LHC ApparatuS), Compact Muon Solenoid (CMS) as well as CMS HGCAL (High Granularity Calorimeter).

When the LHC was originally approved, the already unprecedented luminosity of the accelerator presented formidable challenges. Thanks to Hamamatsu Photonics’ silicon sensors and avalanche photo diode technologies, these have been successfully overcome and the discovery of the Higgs Boson stands as a centrepiece of 21st century science, completing a major chapter in the history of fundamental physics.

The upgrade of the ATLAS and CMS trackers will far exceed the performance of the existing installations. The CMS HGCAL will also be the first large-scale deployment of a highly granular calorimeter in a collider experiment. The High Luminosity LHC (HL-LHC) project takes these challenges to a new level and both the ATLAS and CMS experiments have developed ambitious new projects to fully exploit the scientific potential of the upgraded LHC. HL-LHC will open the way for the next chapter in the field, at the core of which will be the detailed exploration of the Higgs Boson’s properties.

Procurement contracts with CERN often entail the development of state-of-the-art solutions, challenging companies to innovate and supply novel technologies. The ATLAS and CMS upgraded trackers will require the production of about 45’000 6-inch sensor wafers, close to twice what was required for the existing trackers. An 8-inch silicon sensor production line has been implemented for the HGCAL, which will require close to 30’000 8-inch sensor wafers, corresponding to some 600 sqm of silicon sensors.
