This paper reports on the influence that temperature during irradiation and dose-rate have on the radiation-induced free-radical yield and time stability in non de-proteinized bone. Bone from chicken legs was irradiated in the 253-293 K temperature range and with two different sources (60Co, 0.6 Gy/s and 12 MeV electrons, 6 x 10(6) Gy/s). Temperature(More)
The influence of γ-ray irradiation on the optical properties of Bi(2)O(3)-B(2)O(3)-SiO(2) glass has been investigated. Broadband infrared (IR) emission at 1310 nm with a FWHM over 200 nm is observed in the γ-ray irradiated glass. The IR luminescence depends on the γ-ray irradiation dose and the concentration of Bi(2)O(3). The thermal stability of the γ-ray(More)
GaN and SiC power devices were extensively tested under different types of radiation, in the framework of the APOLLO R&D collaboration, aiming to use these new technologies for designing power supplies for the future LHC experiments upgrades. SiC power MOSFETs were irradiated with -rays, neutrons, and heavy ions (Iodine, Bromine) at different energies(More)
A single-particle theory of the evolution of the harmonic content of a bunched beam in a relativistic optical klystron is reported. The equations of motion of the electrons in the dispersive-magnetic-drift space are solved analytically, including the effects of the energy and angular spreads of the beam. The theory enables one to predict the optical(More)
The light produced in each of the 60 thousand PbWO 4 (PWO) crystals of the CMS barrel electromagnetic calorimeter will be readout by Avalanche Photodiodes (APD). The ratio detected to emitted photons also depends on the PWO//APD gluing quality that must be checked before the crystal mounting inside the calorimeter. In this paper two different tools are(More)
The aim of the LUMEN cooperation , supported by INFN, is to obtain full experimental characterisation and deep expertise of heavy scintillator for high energy physics. The advantage of this collaboration was mainly in the complementary character of the experimental techniques available in the partner laboratories and in the availability of highly(More)
A method was investigated to measure gamma and fast neutron doses in phantoms exposed to an epithermal neutron beam designed for neutron capture therapy (NCT). The gamma dose component was measured by TLD-300 [CaF2:Tm] and the fast neutron dose, mainly due to elastic scattering with hydrogen nuclei, was measured by alanine dosemeters [CH3CH(NH2)COOH].
