An apparatus for pulsed ESR and DNP experiments using optically excited triplet states down to liquid helium temperatures

Arnaud Comment, Sami Jannin, Jacques Van Der Klink, Tim Rolf Eichhorn, Martin Haag

In standard Dynamic Nuclear Polarization (DNP) electron spins are polarized at low temperatures in a strong magnetic field and this polarization is transferred to the nuclear spins by means of a microwave field. To obtain high nuclear polarizations cryogen ...

Energy-selective neutron imaging for morphological and phase analysis of iron-nickel meteorites

Steven Luc X Peetermans

We propose energy-selective neutron imaging as a new and non-destructive method to investigate rare metallic meteorites. It is based on attenuation of a neutron beam of limited spectral distribution in a sample depending on the elemental composition and cr ...

Characterization of Extended Range Bonner Sphere Spctrometers in the CERF high-energy broad neutron field at CERN

Nikolaos Charitonidis, Angelo Esposito, Marco Silari

The accurate determination of the ambient dose equivalent in the mixed neutron-photon fields encountered around high-energy particle accelerators still represents a challenging task. The main complexity arises from the extreme variability of the neutron en ...

High-resolution gamma ray spectroscopy measurements of the fast ion energy distribution in JET 4He plasmas

Patrick Blanchard

High-resolutionγ-ray measurements were carried out on the Joint European Torus (JET) in an experiment aimed at accelerating 4He ions in the MeV range by coupling third harmonic radio frequency heating to an injected 4He beam. For the first time, Doppler br ...

Spin filtering neutrons with a proton target dynamically polarized using photo-excited triplet states

Tim Rolf Eichhorn

In a test of principle a neutron spin filter has been built, which is based on dynamic nuclear polarization (DNP) using photo-excited triplet states. This DNP method has advantages over classical concepts as the requirements for cryogenic equipment and mag ...

Experimental study and FLUKA simulations of a prototype micromegas chamber in a mixed neutron and photon radiation field

Nikolaos Charitonidis, Francesco Cerutti

Detectors based on the micromegas principle have already been used in several atomic, nuclear and particle physics experiments. They have also been proposed as one of the options to upgrade the ATLAS muon spectrometer in the very forward/backward region. T ...

Fast ions in mode conversion heating (He-3)-H plasmas in JET

Mikhail Maslov, Yu Lin

Fast ions were analysed in experiments focusing on fundamental He-3 minority and mode conversion (MC) in the ion cyclotron resonance range of frequencies (ICRF) in H plasmas and on second harmonic heating of He-3 ions at 2.65 T mimicking D-T plasma heating ...
