| 31. | He oversaw LANL's participation in the Joint Genome Institute and in the construction of the Spallation Neutron Source.
|
| 32. | In 1977 financial approval was given to convert the Nimrod facility into the Spallation Neutron Source ( SNS ) named ISIS.
|
| 33. | Nuclear spallation is one of the processes by which a particle accelerator may be used to produce a beam of neutrons.
|
| 34. | Helium-3 is created by cosmic ray bombardment, and by lithium spallation reactions which generally occur in the crust.
|
| 35. | Isotopes such as lithium-6, as well as some beryllium and boron are generated in space through cosmic ray spallation.
|
| 36. | Carbon and oxygen nuclei collide with interstellar matter to form lithium, beryllium and boron in a process termed cosmic ray spallation.
|
| 37. | This is increased to just under 10 17 n cm-2 s-1 for spallation sources ( e . g.
|
| 38. | Three slots are left empty at the center of the core to allow space for the spallation target or for material irradiation.
|
| 39. | There, in striking atomic nuclei, among other reactions they induce spallation reactions in which a neutron is liberated from the nucleus.
|
| 40. | The disadvantages of both proton and spallation neutron sources can be avoided by using mono-energetic 14 MeV neutrons for SEE testing.
