چکیده

A 60 kV neutral lithium diagnostic beam probes the edge plasma of JET for the measurement of electron density profiles. This paper describes recent enhancements of the diagnostic setup, new procedures for calibration and protection measures for the lithium ion gun during massive gas puffs for disruption mitigation. New light splitting optics allow in parallel beam emission measurements with a new double entrance slit CCD spectrometer (spectrally resolved) and a new interference filter avalanche photodiode camera (fast density and fluctuation studies).

Electron Density Profiles from the Probabilistic Analysis of the Lithium Beam at JET

Introduction The lithium beam diagnostic provides a powerful edge plasma diagnostic. It enables the determination of electron density profiles in the scrape-of-layer and pedestal region with high spatial and temporal resolution (∆t ≈ 50ms, ∆x ≈ 1cm). A fast neutral lithium beam (beam energy at JET: 55 keV) is injected into the plasma and the line radiation emitted by the collisionally excited l...

Deuteron beam interaction with lithium jet in a neutron source test facility I

Testing and evaluating candidate fusion reactor materials in a high-flux, high-energy neutron environment are critical to the success and economic feasibility of a fusion device. The current understanding of materials behavior in fission-like environments and existing fusion facilities is insufficient to ensure the necessary performance of future fusion reactor components. An accelerator-based ...

Analysis of beam-on-target interaction in a neutron-source test facility *

The need is urgent for a high-flux, high-energy neutron test facility to evaluate the performance of fusion reactor materials. An accelerator-based deuterium-lithium source is generally considered the most reasonable approach to a high-flux neutron source in the near future. The idea is to bombard a high-energy (20-40 MeV) deuteron beam into a lithium jet target to produce high-energy neutrons ...
