Status of the ITER ECRH&CD control system development [PDF]

EPJ Web of Conferences, 2023
The ITER ECRH&CD system is designed to inject 20 MW of millimetre-wave at 170 GHz into the vacuum vessel. The system is composed of many sub-systems, namely High-Voltage Power Supplies (HVPS), Gyrotrons, Transmission Lines (TL), Ex-vessel Waveguides (EW),

Differentiating multi-MeV, multi-ion spectra with CR-39 solid-state nuclear track detectors

Scientific Reports, 2023
The development of high intensity petawatt lasers has created new possibilities for ion acceleration and nuclear fusion using solid targets. In such laser-matter interaction, multiple ion species are accelerated with broad spectra up to hundreds of MeV ...

Membrane Fusion [PDF]

Cell, 2003
Membrane fusion, one of the most fundamental processes in life, occurs when two separate lipid membranes merge into a single continuous bilayer. Fusion reactions share common features, but are catalyzed by diverse proteins. These proteins mediate the initial recognition of the membranes that are destined for fusion and pull the membranes close together

Preceding propagation of turbulence pulses at avalanche events in a magnetically confined plasma

Scientific Reports, 2022
The preceding propagation of turbulence pulses has been observed for the first time in heat avalanche events during the collapse of the electron internal transport barrier (e-ITB) in the Large Helical Device.

Experimental determination of the cooling efficiency of a high-temperature surface by a pneumatic nozzle [PDF]

E3S Web of Conferences, 2023
The cooling of surfaces that perceive high heat fluxes (more than 7 MW/m2) at the current pace of development of the energy sector will become one of the main problems of the near future. In this paper, as one of the options for effective cooling of high-

Overview of the ICRF heating system in SPARC [PDF]

EPJ Web of Conferences
Ion Cyclotron Range of Frequencies (ICRF) heating is a critical system for the SPARC mission of demonstrating net positive fusion gain. In the first campaign, 20 MW of installed power at 120 MHz will be supplied to 10 four-strap antennas, arranged in ...

FUSION RESIDUES [PDF]

Modern Physics Letters A, 1991
We discuss when and how the Verlinde dimensions of a rational conformal field theory can be expressed as correlation functions in a topological LG theory. It is seen that a necessary condition is that the RCFT fusion rules must exhibit an extra symmetry. We consider two particular perturbations of the Grassmannian superpotentials.

Long-pulse Plasma Discharges by Upgraded ECH System in the LHD

EPJ Web of Conferences, 2015
Until 2009, three high-power, over 1MW each, 77GHz gyrotrons have been installed and applied to the LHD experiment. In addition, a 154GHz gyrotron of 1MW was installed in 2012. The 77GHz gyrotrons suffer gradual increases of internal pressure during long-

DIII-D High Field Side Lower Hybrid Current Drive Experiment Overview [PDF]

EPJ Web of Conferences
In preparation for high field side lower hybrid current drive (HFS LHCD) experiments in DIII-D, the HFS LHCD was to be commissioned and physics experiments commence once the system operated up to 300 kW for 0.5 s.

Comparison between measurement and calculations for a 14 MeV neutron water activation experiment [PDF]

EPJ Web of Conferences, 2020
The nuclear heat loads due to gamma rays emitted from the decay of 16N and delayed neutrons from17N, generated by the activation of water in cooling circuits, are critical for ITER design. The assessment of nuclear heating from activated water is complex;
