CERN is a large
multidisciplinary organisation that requires a wide range of goods and services
in order to construct and operate its accelerators, detectors and computing
facilities. Procurement contracts with CERN often entail the development of
state-of-the-art solutions, challenging companies to innovate and supply novel
technologies.
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 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.
The upgrade of the
ATLAS and CMS trackers will far exceed the performance of the existing
installations. The CMS High Granularity
Calorimeter (HGCAL) will also be the
first large-scale deployment of a highly granular calorimeter in a collider
experiment.
On 23 August
2019, CERN and Hamamatsu
Photonics signed a series of three contracts for the supply of silicon sensors for the ATLAS and CMS
trackers and the CMS HGCAL. 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 600m2 of silicon sensors.
About these
contracts, Anders Unnervik, Head of Procurement and Industrial Services at CERN,
commented:
“These contracts are essential to the next phase of CERN’s core research program, namely the
HL-LHC as they will ensure the supply of high-quality silicon sensors that will contribute to important advancements for both experiments.”
Koei Yamamoto, Senior Managing Director at
Hamamatsu Photonics, said:
“We are
very honored and also a bit proud today. Proud to sign these three significant
contracts, proud to have been selected for the supply of silicon
sensors, proud to be part of this next epoch making experiment in particle
physics, where the Higgs Boson is known – but what will be next? We are also
thankful. Thankful to all scientists who pushed us year by year and experiment
by experiment to higher performances.
Not least, it is this very close collaboration based on knowledge, trust and
understanding which led us to signing the contracts with confidence of both
parties. Tied to the confidence, CERN transferred also a very high
responsibility to Hamamatsu Photonics’ Solid State Division. We are very
well aware of this and we will do the outmost to fulfill our part in order that
this endeavor will lead to a great success and new discoveries.”
