Production of the ITkPixV1 chip for the ATLAS pixel detector at the HL-LHC
On March 17 2020, the ITkPixV1 chip was submitted to the TSMC foundry for production. With a surface area of more than 4 cm², this chip has been designed in the 65 nm CMOS process and will tolerate an ionizing dose of more than 500 Mrad. It contains more than 1/2 billion transistors and 153,600 pixels of 50x50 µm² organized in 2,400 regions of 8x8 pixels. This is the culmination of nearly 8 years of work by CERN's RD53 collaboration, to which the CPPM's ATLAS team has been a major contributor since its foundation. This is the pre-production version of the chip which will equip, in more than 33,000 units, the 5 internal pixel layers of the future ATLAS post-2026 trajectograph. This is a major step towards improving the ATLAS detector for the High Luminosity phase of CERN's Large Hadron Collider, which has now been completed.

CANCELLED The CPPM participates in International Masterclasses - hands on Particle Physics
The International Physics Masterclasses - courses and practical work in particle physics - for high school students from all over the world will take place from 26 February to 8 April 2020. The Centre de Physique des Particules de Marseille is offering five sessions for high school students from the region between 9 March and 7 April.
KM3NeT - Depth Dependence Paper Published and Citable
The paper "Dependence of atmospheric muon flux on seawater depth measured with the first KM3NeT detection units” has been published on Europhysics Journal C and is now fully citable as: Eur. Phys. J. C (2020) 80:99, M. Ageron and al.
Dernière modification: Apr 24, 2023, 9:28:03 AMA new step for the French KM3NeT project
The CPPM's KM3NeT team has completed the construction of the second junction box, one of the main components for the KM3NeT project. It will be deployed coming soon, at a depth of 2500 meters, 40 kilometers off the coast of Toulon.
