A first principles 6D kinetic model is developed to study the earliest times of unassisted plasma breakdown in an International Thermonuclear Experimental Reactor (ITER)-scale tokamak. This is then used for a comparative study of the predicted ionisa

Townsend discharge theory is commonly used to describe and approximate the ionisation fraction growth rate in the very early phase of plasma initiation in tokamak devices via ohmic breakdown. The prediction of the ionisation fraction growth rate is d

Julich Supercomputing Centre (JSC) started running (extreme) scaling workshops with its first IBM Blue Gene supercomputer, finally spanning three generations each seeing an increase in the number of cores and available threads. Over the years, this w

Particle-in-cell (PIC) methods are widely used on today’s supercomputers. In this paper we consider JuSPIC, an application for which good scaling properties could be demonstrated on a 6 PFlop/s BlueGene/Q system. We report on efforts to port this a

Feedback from the previous year's very successful workshop motivated the organisation of a three-day workshop from 1 to 3 February 2016, during which the 28-rack JUQUEEN BlueGene/Q system with 458 752 cores was reserved for over 50 hours. Eight inter

We present physical results obtained from simulations using 2+1 flavors of domain wall quarks and the Iwasaki gauge action at two values of the lattice spacing $a$, ($a^{-1}$=\,1.73\,(3)\,GeV and $a^{-1}$=\,2.28\,(3)\,GeV). On the coarser lattice, wi

We present results for the first two moments of the light-cone distribution amplitudes of the pion and kaon pseudo-scalar mesons and of the rho, K* and phi vector mesons. The calculations are performed on the RBC/UKQCD collaborations' ensembles gener

Quantum-Chromodynamics (QCD) is the theory of quarks, gluons and their interaction. It has an important almost exact symmetry, the so-called chiral symmetry (which is actually broken spontaneously). This symmetry plays a major role in all low-energy
