Helsinki Institute of Physics

The Helsinki Institute of Physics is operated by the University of Helsinki, Aalto University, the University of Jyväskylä, Lappeenranta University of Technology and Tampere University of Technology. The Institute has, since 1997, had a national mandate from the Finnish Ministry of Education and Culture to co-ordinate the collaboration between CERN and Finland. The HIP CMS Programme is responsible for coordinating the Finnish participation in the CMS and TOTEM experiments. The programme is divided into four projects: (1) the CMS Experiment, responsible for physics analysis and operations, (2) the CMS upgrade, responsible for the Finnish contribution to the CMS upgrades, (3) the WLCG Tier-2 and (4) the TOTEM projects. The HIP physics analysis team takes active part in the CMS computing, software and analysis effort. The activities range from detector and physics simulation studies in view of exploring the CMS physics performance to the reconstruction and analysis of the events. During the past years, HIP researchers have contributed especially to Higgs, jet, and B-physics analyses and Tracker alignment.

The HIP-CMS Upgrade team is responsible for the Finnish hardware contribution to the CMS Experiment. Since 2013 until the beginning of 2017 the main activity was the Phase-1 Upgrade of the Pixel Tracker. In this phase, the team had a significant contribution to the Barrel Pixel Tracker’s upgrade and delivered, with Advacam Ltd., 250 flip-chip bonded bare detector modules for the third layer (L3) of the upgraded Barrel Pixel Tracker. For the Phase-2 Upgrade, anticipated to happen in around 2023, Finland is planning to participate in the upgrades of the Pixel Tracker, outer Tracker mechanics, and GEM GE1/1 station.
