My brother Norman McCubbin, who has died aged 77, was a scientist who worked at the forefront of experimental particle physics.
A leading light in experiments that took place on the Large Hadron Collider, the world’s biggest and most powerful particle accelerator at the European Organization for Nuclear Research (Cern) in Switzerland, he spent the last five years of his working life as director of the particle physics department at the Rutherford Appleton Laboratory (RAL) in Oxfordshire, until his retirement in 2012. Afterwards he became a tutor to undergraduates at St Anne’s College, Oxford, and was still in that role at his death.
