AbstractAbstract
[en] The use of secondary electron emission to detect high energy particles is investigated. Low density KCl layers have been tested to detect MeV electrons, 500 MeV proton and high energy deuterons and tritons. The efficiency and the secondary electron spectra are presented. The results justify the use of low-density KCl layer to detect minimum ionizing particles. Actually the timing resolution for different KCl thicknesses is lower than 250 ps

L'emission d'electrons secondaires comme moyen de detection des particules de haute energie est employee. Des cibles de chlorure de potassium poreux ont ete testees avec des protons d'energie superieure a 400 MeV ainsi qu'avec des deutons et tritons de haute energie. Les efficacites et les spectres d'electrons secondaires emis sont presentes. Des mesures de temps obtenues avec ces cibles associees a des galettes de microcanaux sont presentees. Les resultats justifient l'emploi de ces cibles poreuses pour la detection des particules au minimum d'ionisationOriginal Title

AbstractAbstract
[en] The four elliptic emission functions v(y), t(y), s(y) and theta(y) [or f/sub m/g(y)] are used in calculating electron emission from surfaces under the influence of temperature and external electric fields. Critical evaluations are made of the published tables of these functions. Several existing approximation equations for the emission functions are given together with some additional polynomial approximations. The estimated accuracies of these approximation equations range from five to six significant figures for the most complex approximations to +- 1% or so for the simplest

AbstractAbstract
[en] We present pre-equilibrium models of cluster (deuterons to alphas) emission from reactions induced by light projectiles at energies below the pion threshold. The main attention is given to the hard components of the emission spectra. The pre-equilibrium mechanisms of cluster emission show a kind of competition between pickup and knockout reactions in some cases, in addition to the classical coalescence. We discuss the processes in force and the interplays of competing mechanisms. (author)

AbstractAbstract
[en] The authors have made use of the cooling-down phenomenon produced by the kinetic energy which is carried away by the electrons to study the functioning of the heated field emission cathode. They put emphasis on the succession of three different rates of working and saturation effect. These phenomena allow to offer an explanation about the steadiness of this cathode. (Auth.)

AbstractAbstract
[en] Thermoluminescence (TL) emission spectra have been obtained from alkali feldspars ranging from monoclinic and triclinic potassium-rich feldspars to tricline sodium-rich feldspars, as well as from a synthetic gel of KA1Si3O8 composition. Emissions were detected in the wavelength range 200-800 nm using a high sensitivity spectrometer. The results suggest that the 290 nm emission band in TL is associated either with the presence of crystalline phases of NaA1Si3O8 or with Na/K exsolution interfaces. (author)
