How to clean up New Delhi's smoggy air
An international study led by atmospheric researchers at PSI shows for the first time what portions of particulates in the air over northern India are especially harmful to health.
The Paul Scherrer Institute (PSI) is a multi-disciplinary research institute which belongs to the Swiss ETH-Komplex covering also the ETH Zurich and EPFL. It was established in 1988 by merging in 1960 established EIR (Eidgenössisches Institut für Reaktorforschung = Federal Institute for Reactor Research) and in 1968 established SIN (Schweizerisches Institut für Nuklearphysik = Swiss Institute for Nuclear Physics). The PSI is a multi-disciplinary research centre for natural sciences and technology. In national and international collaboration with universities, other research institutes and industry, PSI is active in solid state physics, materials sciences, elementary particle physics, life sciences, nuclear and non-nuclear energy research, and energy-related ecology. It is the largest Swiss national research institute with about 1,400 (year 2011) members of staff, and is the only one of its kind in Switzerland. PSI is a User Laboratory and runs several particle accelerators. The 590MeV cyclotron, with its 72MeV companion pre-accelerator, is one of them. As of 2011, it delivers up to 2.2mA proton beam, which is the world record for such proton cyclotrons.
