Progress towards robotic in-situ dating of martian sediments using optically stimulated luminescence
Recent exploratory efforts to reveal the evolution and the climatic history of Mars have shown that the planet is still active. The surface of Mars has been, and continues to be, shaped by fluvial, eolian and glacial processes. The timeframe of these events is, however, poorly established. We describe efforts and challenges to adapt optically stimulated luminescence (OSL) dating for robotic in-...
متن کاملOptically Stimulated Luminescence Dating (Instrument Design for Mars Applications)
Introduction: To examine the geological and climatic history on Mars, we investigate an instrument design for robotic, in-situ, Optically Stimulated Luminescence dating (OSL). In this paper, we discuss the basic concepts of OSL, its benefits, and how this technique can be utilized on Mars. Also presented are the vital electronics needed for an instrument design and some of their basic operation...
متن کاملTest of household salt read by optically stimulated luminescence (OSL) as a personal dosemeter
This study has investigated the optically stimulated luminescence (OSL) of household salt and chemically pure NaCl after exposure in different radiation environments. The response relative to thermoluminescent dosimetry using LiF has been investigated to determine if OSL in NaCl can be considered as an alternative to measurements of thermoluminescence in LiF. A selection of staff members at the...
متن کاملOptically stimulated luminescence (OSL) of carbon-doped aluminum oxide (Al2O3:C) for film dosimetry in radiotherapy.
INTRODUCTION AND PURPOSE Conventional x-ray films and radiochromic films have inherent challenges for high precision radiotherapy dosimetry. Here we have investigated basic characteristics of optically stimulated luminescence (OSL) of irradiated films containing carbon-doped aluminum oxide (Al2O3:C) for dosimetry in therapeutic photon and electron beams. MATERIALS AND METHODS The OSL films co...
متن کاملOptically stimulated luminescence studies on CaF2:N using CW and LM OSL techniques
Natural calcium fluoride (fluorite CaF2:N) exhibits multiple LMOSL peaks when stimulated using blue LED’s, which makes it an unique phosphor. Such a property is not observed experimentally in any other dosimetric phosphors namely Al2O3:C, BeO etc. This makes CaF2:N as an effective tool not only for testing the kinetic models of luminescence but also for investigating OSL using CW and LM stimula...
