The Large Hadron Collider (LHC) at CERN, the European Laboratory for Particle Physics, is the world's largest particle accelerator enabling searches for new physics in particle collisions at record energies. To find even rarer signals, the accelerator will be upgraded to a high-luminosity LHC (HL-LHC). Finland participates in two large LHC experiments, CMS and ALICE. The current CMS charged particle tracking system will not survive the harsh HL-LHC radiation environment. Therefore, a completely new tracker with improved performance is required to be able to look for physics beyond the known Standard Model of particle physics at the HL-LHC. ALICE will build a new Forward Calorimeter (FoCal) to seek evidence for gluon saturation, a fundamental property of strong interactions. The project provides Finland's contribution to the new CMS tracker. An automatic bonding machine will be acquired for the Helsinki Detector Laboratory to produce parts for the CMS tracker and the ALICE FoCal.
