Measurement of the neutron spectrum from the reaction of 30-MeV deuterons on a thick beryllium target

Description: Measurements were made of the neutron spectrum produced by bombarding a thick beryllium target with 30-MeV deuterons at the University of California, Davis cyclotron. This spectrum is of interest in studying the effect of neutrons on materials to be used in future fusion reactors. The spectrum was inferred from the activation of two sets of detector foils placed at 0/sup 0/ to the deuteron beam, one immediately behind the beryllium target block, and one 40 mm to the rear. A least-squares progra… more

Examination of failed drill bit from geysers field

Description: A Reed Tool Compsny 73JA drill bit used in the Geysers geothermal field failed primarily because of severe frictional wear of the nose bearing. There is no indication that well temperature by itself caused failure of any part of the bit. However, the high well temperature together with the friction heat generated produced a temperature which lead to softening and premature wear failure of the nose bearing.
