Tokamak GOLEM for (worldwide) fusion education

The smallest and oldest tokamak with the biggest control room in the world

Universities are welcome to exploit the possibilities of the both remote and in situ operation of the tokamak GOLEM for educational purposes. Half or whole day sessions for group of students are excelent introduction to the physics and technology practice of thermonuclear fusion in the magnetic confinement.

Training courses: left) on site; right) remote.


Tokamak GOLEM is ready to serve as an in-situ or a remote educational tool for various presentations, lectures and training courses in the field of physics and technology of tokamaks. Students can operate the tokamak via web interface:

and instantly can access the results via shot homepage:

Tokamak GOLEM

  • Dear GOLEM team, let me congratulate you to the first plasma in GOLEM achieved in the frame of the Summer Training Course 2009. This success is a result of your enormous effort to put the GOLEM tokamak in operation during the period of about one year. I can confirm that the participants (students and supervisors) found the experiments performed yesterday extreemly interesting and enjoyed them very much.

    On behalf of the old CASTOR and new COMPASS team, Jan Stockel

  • First of all, we would like to express our gratitude for this remarkable opportunity. To perform a remote measurement on a tokamak, and to be part of such an international operation for the first time in our life, is way beyond our earlier expectations as physics students. We wish you luck for the future, and lots of plasma :)

    Andras Karman, Gergely Klujber, Mate Ferenczy and Peter Nemetvarga (BME Hungary)

  • Thanks for the operation! The lab exercise went perfectly well, and the students were really enjoying it.

    Gergo Pokol (superisor and teacher at HUNTRAIC)

  • I just wanted to thank you for coming in Cadarache to introduce us to the amazing work youve done with the GOLEM tokamak. It is fascinating to be able to work on such a device, and were really enjoying the possibility to make our very first discharges .. From all of us, thank you again.

Production issues

(difficult to describe it, this is only for basic understanding, please contact us for more details)

  • Various models to consider (student group somewhere in the world undergoing some thermonuclear fusion education specific event - training course, plasma/tokamak school/subject, etc. ):
    • Somebody from the GOLEM team can come to the institution and deliver the presentation about the tokamak GOLEM, it’s operation, data manipulation and possible task to perform personally (preferably) or remotely via some kind of videoconferencing. Then one or more days later the real remote session could be established.
    • Somebody experienced in the field of tokamak physics, technology and operation learn the GOLEM specific issues, undergoes introductory GOLEM operation training in advance and then it is possible proceed to the the real remote session for students.
