TJ-I
The TJ-I tokamak was the first magnetic confinement device at CIEMAT (then JEN). It started operation in 1983, and has been operational until 1995. Ohmic heating was used.
This device has been the subject of many research programmes dedicated to the study of physical processes in tokamak plasmas:
- basic confinement studies (transport, electric fields, isotope effect)
- edge physics
- turbulence studies (driving mechanisms, turbulent transport)
- plasma-wall interaction (carbonization, boronization)
- diagnostic development (microwave reflectometry, radiation detectors, probes, atomic beams,...)
