Vinod Chandrasinh Chohan (1 May 1949 – 12 June 2017)[1] was a Tanzanian-bornaccelerator specialist and engineer. He was a Senior Staff Member at CERN for nearly 40 years.
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.
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.[6] 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. In 1993 he taught a course at the CERN Accelerator School on Accelerator Systems, held at the Centre for Advance Technology, Indore, India.[7]
In 2002, he joined the LHC Project team responsible for developing CERN's new project, the Large Hadron Collider (LHC). Chohan led and managed the team responsible for testing hundreds of superconducting magnets to be used in the collider.[8][9] This was a tedious process: 1706 superconducting magnets – each 14 meters long — were to be tested.[10] From the beginning of the testing in 2001 to 2002, only 21 magnets were tested, due to shortage of staff. The situation improved when one started recruiting personnel from India, for a year at the time, as part of the CERN-India Collaboration on LHC.[10] Over 7 years Chohan led this international team which fully tested, qualified and trained up about 1300 superconducting magnets for use in the LHC. Chohan became member of the joint CERN-Department of Atomic Energy, India committee for the CERN-India Collaboration in 2007.
During the LHC construction, he has featured in London Science Museum's Big Bang exhibition in 2007[11] and in 2008 he was featured in BBCHorizon, a documentary television series.
After the LHC start-up in 2008, Chohan led the team responsible for technical coordination at all of CERN's accelerators and beam experimental areas, except for the LHC.
