Claims (14)

  1. Dispositif de génération de neutrons thermiques pour des essais de diffusion de neutrons, comprenant une source de neutrons (3) entraînée par accélérateur ou par laser et un modérateur (1) pour modérer des neutrons de la source de neutrons (2, 3), caractérisé en ce qu'un canal ou plusieurs canaux (5) se trouve(nt) dans le modérateur (1), lequel/lesquels s'étend(ent) à partir d'une zone intérieure (4) dans le modérateur jusqu'à la surface (6) du modérateur (1), caractérisé en ce que la partie intérieure (4) se trouve au ou dans le maximum de flux de neutrons thermiques.
  2. Dispositif selon la revendication 1, caractérisé en ce que le modérateur (1) consiste en une matière solide et les canaux (5) sont forés dans la matière solide.
  3. Dispositif selon la revendication précédente, caractérisé en ce que la matière solide consiste en béryllium.
  4. Dispositif selon l'une des revendications précédentes, caractérisé en ce que la zone intérieure (4) est arrangée de manière adjacente à la source de neutrons (3).
  5. Dispositif selon l'une des revendications précédentes, caractérisé en ce que la source de neutrons (3) est un convertisseur (3) à l'extrémité d'un accélérateur linéaire (2).
  6. Dispositif selon la revendication précédente, caractérisé en ce que la zone intérieure (4) se trouve, vu dans la direction d'accélération de l'accélérateur linéaire (2), derrière l'accélérateur linéaire.
  7. Dispositif selon l'une des revendications précédentes, caractérisé en ce que la source de neutrons (3) se trouve dans le modérateur (1).
  8. Dispositif selon l'une des revendications précédentes, caractérisé en ce que le modérateur comprend un volume compris entre 100 et 150 litres.
  9. Dispositif selon l'une des revendications précédentes, caractérisé en ce qu'il y a 4-10 canaux (5) dans le modérateur (1), lesquels s'étendent à partir d'une zone intérieure (4) jusqu'à la surface (6) du modérateur (1).
  10. Dispositif selon l'une des revendications précédentes, caractérisé en ce que le diamètre de chaque canal (5) est plus petit que le double du libre parcours moyen des neutrons thermiques dans le modérateur.
  11. Dispositif selon l'une des revendications précédentes, caractérisé en ce que le modérateur (1) est enveloppé par une gaine extérieure en graphite ou en polyéthylène.
  12. Procédé de fabrication d'un dispositif selon l'une des revendications précédentes, caractérisé en ce qu'un maximum de flux de neutrons thermiques dans le modérateur est déterminé et des extrémités des canaux (5) sont disposées dans la zone du maximum de flux déterminé.
  13. Procédé selon la revendication précédente, caractérisé en ce que les surfaces des canaux sont polies à l'intérieur ou sont chemisées d'un revêtement poli.
  14. Dispositif selon les revendications précédentes, caractérisé en ce qu'un filtre en plomb ou en monocristal de saphir est disposé à l'intérieur d'un ou de plusieurs canaux pour filtrer des neutrons rapides primaires.
