recommendations! Published in 2020 at "Fusion Engineering and Design"

DOI: 10.1016/j.fusengdes.2019.111366

Abstract: Abstract HL-2M is a new medium-sized copper-conductor tokamak currently under final construction. Taking into account potential uncertainties in the engineering construction and to resolve design anomalies associated with new machine startup, high loop voltages (>10 V)… read more here.

DOI: 10.1088/1361-6587/ad6a87

Abstract: Tungsten (W) is the most probable material for the plasma-facing components of fusion reactors due to its excellent thermal and physical properties. A W-wall sputtering model has been established to simulate the start-up of a… read more here.

DOI: 10.1088/1741-4326/aa8568

Abstract: Non-inductive plasma start-up is a critical issue for spherical tokamaks since there is not enough room to provide neutron shielding for the center solenoid. Start-up using lower hybrid (LH) waves has been studied on the… read more here.

DOI: 10.1088/1741-4326/ad52a9

Abstract: Establishment of an efficient central solenoid (CS) free tokamak plasma start-up method may lead to an economical fusion reactor. CS-free start-up using lower hybrid (LH) waves has been studied on the TST-2 spherical tokamak. Plasma… read more here.

DOI: 10.1088/1741-4326/ae23e4

Abstract: Low background pressures are expected to be required in ITER for successful plasma breakdown. After plasma implantation, the particles released from plasma-facing components (PFCs) increase pressure in the main chamber, and it is therefore important… read more here.
