Erik Ohlson the British camp during the First World War. Ohlson was succeeded in the baronetcy by his elder son, Sir Eric James Ohlson (1911–1983). Erik Ohlson Sir Erik Olof Ohlson, 1st Baronet (19 July 1873 – 20 March 1934) was a Swedish-born British shipping magnate and coal and timber merchant. Ohlson was a son of a farmer in the village of Oppeby in Fellingsbro parish, Sweden. He spent ten years in the coal importing business in Sweden. In 1902, he emigrated to Hull, England, and established the firm of Ohlson & Co, shipowners and brokers, coal exporters, and timber importers. He
CLAS detector at the center of CLAS. These collisions generally produce new particles, often after the target nucleons (protons and neutrons) are briefly excited to heavier-mass versions of the familiar protons and neutrons. A whole variety of intermediate-mass short-lived particles called "mesons" can be created. Scattered electron as well as the longer-lived produced particles travel through the CLAS detector, where they are measured. Particle physicists use these measurements to deduce the underlying structure of protons and neutrons and to better understand the interactions that create these new particles. The CLAS detector system was operational from 1998 until May 2012. From that time
