Characterization of an integrated sensor using optically stimulated luminescence for in-flight dosimetry

Optically stimulated luminescence materials for wide-spectrum neutron measurements at CERN

“…The OSL reader used in this work is an infrared LED focused on the irradiated specimen that is positioned in a samples holder in a light-tight box. The emitted luminescent signal is collected by means of a photomultiplier, then digitalized and recorded by a PC connected to the test bench via a RS-232 interface [7], [9].…”

“…OSL materials as radiation dosimeters for medical and space applications have been studied extensively [7], [8] High-Energy Physics (HEP) applications, successful experiments were carried out to measure the dose delivered by different charged particles [9]. Since there is a lack of on-line neutron dosimeters for HEP applications, especially for thermal neutron energies, the possibility to make OSL material sensitive to neutrons is a very attractive prospect.…”

Dosimetry Assessments in the Irradiation Facilities at the CERN-PS Accelerator

“…After beam exposure, the OSL exhibits a visible emission spectrum when stimulated with near infrared light [16], [17]. The OSL foil reader is a solid-state laser beam (of about 1.0 m wave length) focused on the irradiated foil that is positioned on a X-Y stage [18].…”

La luminescence stimulée optiquement : Applications à la cartographie de dose et à la mesure de dose en environnement spatial

“…La faisabilité d'un système de dosimétrie en ligne a aussi été démontrée Dusseau, 2000). Ravotti et al, 2004 ;Vaillé et al, 2005Vaillé et al, , 2003Vaillé, 2003 ;Plattard et al, 2002 ;Dusseau et al, 2000) Les premières missions expérimentales telles que le satellite MPTB de la NASA, ou le module ICARE du CNES, spécialement dédiées à l'étude de l'environnement radiatif, ont mis en évidence le caractère dynamique de l'environnement radiatif spatial (Tab. III).…”
