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)
Avalanche photodiodes will be used to detect scintillation light from PbWO4 crystals in the CMS electromagnetic calorimeter. Properties of Hamamatsu APD are reported and special attention has been devoted to the study of radiation hardness and room temperature annealing. We found a fast recovery with a time constant of 1.3 days, a medium fast recovery with(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)

Performance tests of some aspects of the CMS ECAL were carried out on modules of the “barrel” sub-system in 2002 and 2003. A brief test with high energy electron beams was made in late 2003 to validate prototypes of the new Very Front End electronics. The final versions of the monitoring and cooling systems, and of the high and low voltage regulation were(More)
The light produced in each of the 60 thousand PbWO4 (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 co-operation, 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]. The(More)
In the framework of its search for new heavy, fast, and radiation-hard scintillators for calorimetry at future colliders, the Crystal Clear Collaboration performed a systematic investigation of the properties and of the scintillation and radiation damage mechanisms of CeF3 monocrystals. Many samples of various dimensions up to 3×3×28cm3 were produced by(More)
