Abstract In recent years, negative triangularity (NT) has emerged as a potential high-confinement L-mode reactor solution. this work, detachment is investigated using core density ramps in lower single null Ohmic plasmas across wide range of upper, lower, and average (the mean upper triangularity: δ ) the TCV tokamak. It universally found that more difficult to access for NT shaping. The outer divertor leg discharges with <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"...
Abstract We present a model for the particle balance in post-disruption runaway electron plateau phase of tokamak discharge. The is constructed with help of, and applied to, experimental data from TCV discharges investigating so-called ``low-Z benign termination'' mitigation scheme. In termination scheme, free density first reduced order subsequently induced MHD instability to grow rapidly spread electrons widely across wall. show that observed non-monotonic dependence measured neutral...
Blob-like filamentary structures are omnipresent in magnetized plasmas. Their transport deteriorates the particle confinement and may damage plasma-facing components of future fusion devices. In local measurements density, these turbulent seen as high-amplitude bursts, and, since last decade, a stochastic pulse train model (SPTM) has been developed to describe locally measured signals. The SPTM, which is also known filtered Poisson process, models plasma fluctuations superposition pulses...

In recent years, negative triangularity (NT) has emerged as a potential high-confinement L-mode reactor solution. this work, detachment is investigated using core density ramps in lower single null Ohmic plasmas across wide range of upper, lower, and average (the mean upper triangularity: $\delta$) the TCV tokamak. It universally found that more difficult to access for NT shaping. The outer divertor leg discharges with $\delta\approx -0.3$ could not be cooled below $5~\mathrm{eV}$ through...
