Statistical sampling applied to the radiological characterization of historical waste / Zaffora, Biagio (CERN) ; Magistris, Matteo (CERN) ; Saporta, Gilbert (CNAM, Paris) ; La Torre, Francesco Paolo (CERN)
The evaluation of the activity of radionuclides in radioactive waste is required for its disposal in final repositories. Easy-to-measure nuclides, like γ-emitters and high-energy X-rays, can be measured via non-destructive nuclear techniques from outside a waste package. [...]

Leaching of radionuclides from activated soil into groundwater / La Torre, Francesco Paolo (CERN) ; Silari, M (CERN)
Soil samples collected from the CERN site were irradiated by secondary radiation from the 400 GeV/c SPS proton beam at the H4IRRAD test area. Water samples were also irradiated at the same time. [...]

Single- and multi-foils 27 Al(p,3pn) 24 Na activation technique for monitoring the intensity of high-energy beams / Curioni, A (CERN ; Milan Polytechnic) ; Froeschl, R (CERN) ; Glaser, M (CERN) ; Iliopoulou, E (CERN ; Aristotle U., Thessaloniki) ; La Torre, F P (CERN) ; Pozzi, F (CERN) ; Ravotti, F (CERN) ; Silari, M (CERN)
This paper discusses an experimental study of the spallation reaction 27 Al(p,3pn) 24Na in Al foils exposed to 24 GeVc1 protons, in the context of monitoring the intensity of multi-GeV proton beams through foil activation techniques. Since this reaction is sensitive to secondary neutrons and other energetic secondary hadrons, it is important to evaluate the impact of the foil thickness on the calculation of the beam intensity.

Measurements of 55Fe activity in activated steel samples with GEMPix / Curioni, A (CERN ; Milan Polytechnic) ; Dinar, N (CERN ; Paris U., VI-VII) ; La Torre, F P (CERN) ; Leidner, J (CERN ; RWTH Aachen U.) ; Murtas, F (CERN ; Frascati) ; Puddu, S (CERN) ; Silari, M (CERN)
In this paper we present a novel method, based on the recently developed GEMPix detector, to measure the 55Fe content in samples of metallic material activated during operation of CERN accelerators and experimental facilities. The GEMPix, a gas detector with highly pixelated read-out, has been obtained by coupling a triple Gas Electron Multiplier (GEM) to a quad Timepix ASIC. [...]

Monitoring reactions for the calibration of relativistic hadron beams / Ferrari, A (CERN) ; La Torre, F P (CERN ; Bern U., LHEP) ; Manessi, G P (CERN ; Liverpool U.) ; Pozzi, F (CERN ; Munich, Tech. U.) ; Silari, M (CERN)
The well-known foil activation technique was used to calibrate an ionisation chamber employed for the on-line beam monitoring of a 120 GeV c −1 mixed proton/pion beam at CERN. Two monitoring reactions were employed: the standard 27 Al(p,3pn) 24 Na and the alternative nat Cu(p,x) 24 Na. [...]

Long-term residual radioactivity in an intermediate-energy proton linac / Blaha, J (CERN) ; La Torre, F P (CERN ; Bern U.) ; Silari, M (CERN) ; Vollaire, J (CERN)
A new 160 MeV H−H− linear accelerator (LINAC4) is being installed at CERN to replace the present 50 MeV LINAC2 as proton injector of the PS Booster (PSB). During operation, the accelerator components will be activated by the beam itself and by the secondary radiation field. [...]
