## About this tender

CHIMERA is a planned test rig that aims to replicate the conditions inside a nuclear fusion reactor, excluding the radiation component. Magnets (static and pulse/vertical field magnet) are to be installed as part of the first phase of CHIMERA’s installation (dubbed “THOR”). Cooling systems will need to be implemented to continually maintain four cryogenic compressors for the static magnet (SM), and to cool the VFM.
