Detector Laboratory

Helsinki Detector Laboratory is an infrastructure specialized in the instrumentation of particle and nuclear physics. It is a joint laboratory between Helsinki Institute of Physics (HIP) and the Department of Physics of the University of Helsinki (UH/Physics). The Laboratory provides premises, equipment and know-how for research projects developing detector technologies. The Laboratory team has extensive expertise in the modelling, design, construction and testing of semiconductor and gas-filled radiation detectors. In addition, the personnel and scientists working in the Laboratory take the responsibility to educate new generation of physicists.

Detector Laboratory supports several research and teaching activities of the Division of Particle and AstroPhysics (PAP) and the Doctoral programme in Particle Physics and Universe Sciences (PAPU). In addition, the Laboratory collaborates with the Electronics Research Laboratory, especially in the fields of optical imaging techniques and ultrasonic interconnection technologies. Furthermore, the cooperation with Division of Material Physics Accelerator Laboratory is strong in the field of radiation hard semiconductor detectors. The connection is strong also with the Aalto University Micronova/Nanofab facility.

All the projects present in Detector Laboratory have the objective to provide reliable instruments for large international physics experiments. The Laboratory is specialized in Quality Assurance (QA) of detectors and their components and in detector prototyping. In 2015, the Laboratory hosted several research projects participating in CMS, TOTEM and ALICE experiments at CERN, and NuSTAR experiment at FAIR. To maintain the outstanding expertise of the Laboratory, new detector technologies are actively developed in the framework of CERN CMS, RD39, RD50 and RD51 collaborations.

Providing education in the instrumentation of physics is of outmost importance in Detector Laboratory. The scientists working in the Laboratory lecture courses of semiconductor physics and detector technologies. Research-based hands-on exercises and special assignments are organised in the Laboratory. In addition, doctoral and master students are supervised in their thesis works. In 2015, the major educational effort for the whole team was to organize one-week laboratory course on detector technologies for 20 Nordic post-graduate students in close collaboration with PAPU, University of Uppsala Sweden and Niels Bohr Institute Denmark.

Special emphasize is paid in societal interaction to ignite interest for physics among young people. In 2015, the Laboratory participated in several outreach efforts, e.g. "Science Bazaar" and CERN Master Class. In addition, about 150 high school students with their teachers from different parts of Finland visited the Laboratory for demonstrations about physics and instrumentation. Furthermore, two trainees from the Finnish School of Watchmaking and three secondary school TET-trainees worked in Detector Laboratory.
