Vinod Chohan  Vinod Chandrasinh Chohan (1 May 1949 – 12 June 2017) was a Tanzanian-born accelerator specialist and engineer. He was a Senior Staff Member at CERN for nearly 40 years. He held a leading position at CERN's Antiproton Accumulator, a machine that was part of the infrastructure connected to the UA1 and UA2 experiments, where the W and Z bosons where discovered in 1983. Carlo Rubbia and Simon van der Meer received the 1984 Nobel Prize in Physics for this discovery. Chohan worked closely with the latter on the antiproton accumulator. Chohan was a substantial contributor to the Large Hadron Collider (LHC), leading the team that tested, measured and trained more than a thousand superconducting magnets for the LHC. During his nearly 40 years as a staff member at CERN he held technical and management positions such as in beam diagnostics, instrumentation, accelerator studies, controls, testing of superconducting magnet and safety. Vinod Chohan was born in Dar es Salaam, Tanganyika on 1 May 1949 into a Saurashtran Gujarati Indo-Tanzanian Hindu family. He commenced his secondary education at Govt Indian Secondary School, later called Azania Secondary School in Upanga, Tanzania, and in 1967, moved to Colston's School in Bristol. Chohan studied electrical and electronic engineering at University College, Cardiff, and obtained his PhD at University of Essex in 1974. Vinod Chohan joined CERN in January 1975 as a Fellow in the Proton Synchrotron division. From 1977 to 1980 he worked at Swiss Institute for Nuclear Research, in the Beam Dynamics Group of the Cyclotron Accelerator Division. In 1980, he returned to CERN as a staff member in the Proton Synchrotron division, under which he later worked with beam diagnostics and safety. During his nearly 40 years at CERN he has held various positions, such as Accelerator Operation Coordinator for the Antiproton Accumulator Complex. This machine created antiprotons for the Super Proton Synchrotron, and was part of the infrastructure that led to the discovery of the W and Z bosons for which Carlo Rubbia and Simon van der Meer received the 1984 Nobel Prize in Physics. During his tenure at CERN, he was associated with Fermilab for the commissioning of an antiproton source 1985 and 1986 and at the Los Alamos National Laboratory where he collaborated on Proton Storage Ring in 1989.
