Description
The COMPASS tokamak, originally constructed and operated at UKAEA in UK, has been
reinstalled at the Institute of Plasma Physics of the CAS in 2009 and experienced a fruitful
decade of scientific exploration. In this contribution, we will summarize the main
achievements, which have contributed to the physics understanding of tokamak plasmas and
development of nuclear fusion related technologies. These include: (i) investigation of the
power decay lengths in limited plasmas, which directly impacted the design of the ITER inner
wall plasma-facing components, (ii) error field (EF) experiments using the unique set of the
tokamak high-field-side error field coils, (iii) power exhaust studies, (iv) runaway electron
characterization and mitigation programme, and others.
COMPASS tokamak will be shut down before the end of 2020 to make space for a completely
new machine: COMPASS Upgrade. Characteristics of this challenging device will be
presented.
