6. Compact diagnostic systems for X-rays, gammas, and neutrons: a “swiss-knife” detectors portfolio ranging between magnetic confinement fusion, thermal and fast neutrons detection, and laser produced plasmas experiments

Mr Francesco Cordella (ENEA)

Between the various compact diagnostics systems, the hybrid CMOS-based and gas electron multiplier (GEM) detectors of multiple sizes, types, and combinations can offer a real “swiss-knife” solution for the experimental investigation of ionizing radiation. They were used, for many years, by the LabNIXT group of ENEA Frascati on many experimental setups (FTU, KSTAR, EAST, VEGA, GEKKO, etc.). In...

2. Compact diagnostics systems for X-rays, gamma and neutrons based on GEM gas detector, C-Mos imagers and CVD Diamond Detectors for Fast VUV and SX-Ray Tomography

Mr Danilo Pacella (ENEA Frascati)

Among the various compact diagnostics systems, the hybrid CMOS-based and gas electron multiplier (GEM) detectors of multiple sizes, types, and combinations can offer a real “swiss-knife” solution for out-vessel diagnostics of ionizing radiation in experiment of Magnetic and Inertial Nuclear Fusion. They were developed and used, for many years, by the LabNIXT group of ENEA Frascati on many...

8. CVD Diamond Detectors for Fast VUV and SX-Ray Tomography (part2)

Mrs Francesca Bombarda (ENEA)

The excellent photon detection properties of Chemical Vapour Deposition (CVD) single crystal diamonds proved them highly suitable for Vacuum Ultra-Violet and Soft X-ray radiation in-vessel diagnostics of magnetically confined plasmas in a variety of applications [1]. Their radiation and temperature hardness, small size, and high-vacuum compatibility can be exploited for core and divertor...

9. Detection of RF emission by runaway electrons

Dr Paolo Buratti (ENEA)

Detection of plasma waves emitted by runway electrons (RE) provides a sensitive monitor for RE kinetic instabilities, which can reduce energy attained by RE as well as RE confinement. Furthermore, understanding how to stimulate such kinetic instabilities can lead to the development of advanced RE mitigation methods. Emission of radio waves by runaway electrons in the 400 MHz – 3 GHz range has...

3. Impact of Radiation on Optical Fibres at JET

Mikhail Maslov (UKAEA)

Fibres have been installed in the JET Torus hall to determine the impact of radiation on optical fibre during the JET D-T campaign. This talk will show the main affects observed from this work.

10. Multi-energy x-ray imaging systems for long-pulse machines with metal PFCs

Dr Tullio Barbui (PPPL), Dr Oulfa Chellai (PPPL)

The WEST tokamak is currently being prepared for long pulse operation with a water-cooled full metallic first wall to test ITER-like plasma facing components. Tungsten will be the main impurity source in the vessel and its concentration in the core plasma will limit the device performances as it is expected to be the case in ITER. Heating will be provided by radio-frequency systems, including...

5. New developments of the T-Monitor diagnostic

Philippe Mertens (FZ-Juelich)

The tritium monitor diagnostic releases tritium deposited on the inner baffle of the divertor by laser-induced desorption. The tritium that is set free is detected by mass spectrometry (QMS= Quadrupole Mass Spectrometry or RGA= Residual Gas Analysis). After the Conceptual Design Review (CDR), the system was moved in the port plug from the top to the bottom half of the central drawer or...

4. Plasma current measurement at JET using fibre optics current sensor (FOCS)

Andrei Goussarov (SCK CEN)

The Fibre Optic Current Sensor (FOCS) is a supplementary diagnostic system to be installed in ITER to provide data on the plasma current. The FOCS is not standard for plasma current measurements the and sensor performance in a tokamak environment has to be assessed. Considering this goal, polarisation detection based FOCS systems were installed at JET. The measurements were performed in...

1. The potential of THz-TDS diagnostics for next step Fusion experiments

Mr Marco Zerbini (ENEA Frascati)

The Terahertz (THz) band of the electromagnetic spectrum is nowadays defined as a range of frequency [0.1-10] THz, between microwaves and mid-infrared electromagnetic radiation, where electronic and optical technologies overlap. The last decade has seen an enormous development of spectroscopy techniques in this area, with the full development of the so-called Time Domain Spectroscopy (TDS)....
