It is with sadness that UKAEA have learnt of the death of Jan Hugill on 12 March 2020.

Following a PhD in astronomy at Cambridge, Jan was for many years a leading tokamak experimentalist at Culham, rising to leadership of the DITE programme and department when Jim Paul retired. He in turn handed over his department manager role to William Morris when he decided, towards the end of his career, to move to the University Of Manchester Institute of Science and Technology (UMIST) where he was a professor and head of plasma physics. As well as at Culham and in the UK, Jan was very well known in the international fusion community, not least for the “Hugill diagram” of tokamak operating space.
