EFDA provides the work platform to exploit JET in an efficient and focused way. More than 40 Euro – pean fusion laboratories collectively contribute to the JET scientific programme and develop the hardware of the machine further. The tokamak is located at the Culham Science Centre near Oxford in the UK. It is funded by EURATOM, by the Euro – pean Associates, and by UK’s fusion associate, the Culham Centre for Fusion Energy (CCFE) as host. CCFE operates the JET facilities including carrying out the maintenance and refurbishment work required to realise the given scientific goals.
