Fig 3-2, p 47 gives velocity versus density of the above expls, while Fig 3.3 deals with velocity vs diameter for the same expls. Both of these Figs are reproduced here as Figs 1 2 under DETONATION VELOCITY-CHARGE DIAMETER AND DENSITY RELATIONSHIPS. These curves were obtd at large enough.diameters to ensure ideal deton...

Example 4. For a given lattice, a relationship is to be found between the lattice resistivity and temperature usiag the foUowiag variables mean free path F, the mass of electron Af, particle density A/, charge Planck s constant Boltzmann constant temperature 9, velocity and resistivity p. Suppose that length /, mass m time /, charge and temperature T are chosen as the reference dimensions. The dimensional matrix D of the variables is given by (eq. 55) ... 

X-ray absorption furnishes an absolute measure of the density of matter. However, in many applications the important observations to be made with X-rays concern the geometrical relationships of shock fronts and contact surfaces it is in this area where X-rays, because they make it possible to sefe inside the detonating expl, provide a uniquely appropriate tool. Until recently the difficulty has been the inability of available sources to penetrate charges more than a few inches in diameter. With the advent of the PHERMEX machine this difficulty has been overcome. Phermex provides a pulsed beam of 27 Me V electrons in 0.1 microsec bursts, which impinge on a tungsten target to generate X-rays that can easily penetrate several cm of HE. Recall that density of the shocked material can be related to particle velocity thru the conservation equations (see Vol 7, HI 79)...
