8-inch pixel array detector

To meet the high-tech needs of the CMS experimental apparatus in the High Luminosity Large Hadron Collider (also known as the HL-LHC) experiments, Hamamatsu Photonics has designed and developed a unique 8-inch pixel array detector. This size makes it the world’s largest photodiode (PD) with high radiation resistance among PD detectors used in high-energy physics. At present, a mass-production system has also been created for this detector.

Hamamatsu has already supplied opto-semiconductors for the Large Hadron Collider (LHC) project, which is the HL-LHC predecessor, and is thrilled to have played a part in the discovery of the Higgs boson particles (*). Our new 8-inch pixel array detector has both high resistance to radiation and a large area required for the HL-LHC project. These features are expected to contribute to new research including more precise measurements of the Higgs boson properties and the search for dark matter.

We will start full-scale supply of this 8-inch pixel array detector on Monday, February 27, 2023.

* Higgs boson is an elementary particle that is thought to be the origin of mass in the universe, but its detailed properties are still not yet well understood.
