The Lindemann and Grüneisen Laws (open access)

The Lindemann and Grüneisen Laws

The Lindemann assumption of direct contact of neighboring atoms at fusion is replaced by the criterion that melting occurs when the root-mean-square amplitude of thermal vibration reaches a critical fraction ρ, presumed the same for all isotropic monatomic solids, of the distance of separation of nearest-neighbor atoms. The Debye-Waller theory of the temperature dependence of the intensity of Bragg reflection of x-rays is used, without further assumptions, to derive a generalized Lindemann law. In contrast to the Lindemann form, all physical quantities involved in this formulation are evaluated at the fusion point, and departure of the average energy of an atomic oscillation from the equipartition value is taken into account by the quantization factor of the Debye-Waller theory. If the Grüneisen constant γm of the solid at fusion is evaluated by its definition from the Debye frequency of the solid, use of the generalized Lindemann law and Clapeyron's equation permits one to express γm in terms of the bulk modulus of the solid at melting and the latent heat and volume change of fusion. By means of Grüneisen's law applied to the solid at fusion, γm can be expressed likewise in terms of the corresponding bulk modulus, thermal expansion, volume, …

The Separated Beam at the AGS - Performance with Antiprotons and π⁺ Mesons (open access)

The Separated Beam at the AGS - Performance with Antiprotons and π⁺ Mesons

During 1961 and 1962, a separated beam was designed and installed at the AGS for use with the 20 inch hydrogen bubble chamber. The beam utilizes electromagnetic velocity spectrometers in two stages of separation. Since the fall of 1962, the bubble chamber has taken 600,000 pictures containing antiprotons, K± mesons, and π± mesons as beam tracks. This paper concerns the use of the separated beam for antiprotons and π⁺ mesons.

Quarterly Report- July, August, September 1958 Plutonium Fuels Development Plutonium Metallurgy Operation

Examination of Al- 1.65w/o Pu and Al- 12 w/o Si- 1.65 w/o Pu capsules irradiated 55- 60% burnout of the plutonium atoms revealed a 1.4% volume increase and no apparent microstructural changes. A four rod cluster containing Al-8 w/o Pu and Al-12 w/o Si-8 w/o Pu alloy cores is currently under irradiation in Loop 3 of KE Reactor at a water temperature of approximately 230C. A second cluster has been fabricated an is scheduled for charging late in 1958. Two seven-rod clusters for irradiation in KER are also being fabricated.
