Reaction of REBaCuO CC Tapes to Neutron Irradiation

Neutron Reaction Characteristics in LiF Crystals Irradiation

The mean effective cross sections of 6Li for the (n, u) reaction were calculated for thermal, intermediate and fast neutrons; this reaction is dominant in damage production in LiF crystals. The actual neutron spectrum was determined from measurements of thermal, intermediate and fast neutron fluxes, in the core of the IEA-RI-2MW swimming pool reactor, in high fluence conditions, by the activati...

Neutron irradiation of SmFeAsO1−xFx

SmFeAsO1−xFx was irradiated in a fission reactor by a fast (E > 0.1 MeV) neutron fluence of 4 × 1021 m−2. The introduced defects increased the normal state resistivity due to a reduction in the mean free path of the charge carriers. This leads to an enhancement of the upper critical field at low temperatures. The critical current density within the grains, Jc, increases upon irradiation. The se...

Effect of neutron irradiation of MQW lasers to 1015n/cm2

1300nm edge-emitting multi-quantum-well lasers are the baseline choice for the optical transmitter in the CMS tracker optical links. The radiation environment is expected to be ~10Mrad and ~1014(neutron-equivalent)/cm2 over ten years. Lasers from four manufacturers have been irradiated in naked die form with neutron fluences of ~2x1014n/cm2. One laser type was also irradiated in a fully package...

Thermal Diffusivity of Ceramics During Neutron Irradiation

Radioisotopes produced by neutron irradiation of food.

The use of neutrons for cargo interrogation has the potential to drastically improve threat detection. Previous research has focussed on the production of (24)Na, based on the isotopes produced in pharmaceuticals and medical devices. For both the total activity and the ingestion dose we show that a variety of isotopes contribute and that (24)Na is only dominant under certain conditions. The com...
