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 extensive know-how for research projects developing detector technologies. The personnel of the Laboratory have 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 proudly the responsibility and privilege in educating new generation of physicists and in hosting high school students interested in physics.

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 2014, the Laboratory hosted several 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.

Detector Laboratory supports several research activities of UH/Physics. The connection to the Division of Particle Physics and Astrophysics (PAP) is naturally very tight. 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 University of Jyväskylä Accelerator Laboratory and with the Aalto University Micronova facility.

In Detector Laboratory, special effort is devoted to develop methods of social interaction to ignite interest in physics among young people. In 2014, the Laboratory participated willingly in all the outreach efforts organized by UH/Physics, e.g. "Tiedebasaari", "Koekampus", and Higgs weekend at Heureka where the special contribution of the Laboratory was a radiation detector made of lemonade can. In 2014, totally 250 high school students with their teachers from different parts of Finland visited the Laboratory for demonstrations about physics and instrumentation. In addition, 20 high school physics teachers during their summer course of continuation education and 40 starting UH/Physics students visited the Laboratory. Furthermore, two secondary school TET-trainees worked in the Laboratory.

In 2014, the physics education given by Detector Laboratory was further developed. New infrastructure was acquired not only to further improve the research activities but also to establish new research-based exercises and special assignments for physics students. Scientist working in the Laboratory also took responsibility to lecture courses of UH/Physics about semiconductor physics and detector technologies. In addition, project scientists and laboratory personnel acted as mentors to several students working in the Laboratory for their doctoral and master theses.
