Production of mesons by x-rays by Edwin M McMillan( Book )
2 editions published in 1950 in English and held by 6 libraries worldwide
At the spring, 1949, meeting of the National Academy of Sciences(l) a preliminary account was given of some observations of mesons produced by the 335 Mev x-ray beam from the Berkeley synchrotron. The present paper is a progress report of this work; no claim is made for completeness, but sufficient new data are available to make publication at this time worth while, especially since some of the numerical results given in the earlier report require revision. The x-ray beam, produced by the impact of 335 Mev electrons on a 20 mil thick platinum target, has a width at half maximum of 0.0135 radian (about 1 inch at 6 feet from the target). In all but the earliest experiments the beam was further defined by a 1 inch hole in a lead block, then passed through a piece of carbon which served as the meson source. The x-ray intensity at one meter from the target was about 3500 r per hour (measured behind 1/8 inch of lead) under the best running conditions; the average was about half this. The actual exposures at the carbon meson source (6 feet from the target) ranged from 500 to 2000 r in the later runs. Mesons were recorded on Ilford nuclear plates; the highest density of meson endings observed was about 100 per square centimeter in a 100 micron emulsion. In the following sections the experimental conditions and some of the results are described in more detail

Focusing in linear accelerators by Edwin M McMillan( Book )
2 editions published in 1950 in English and held by 5 libraries worldwide
It is well known that phase stability and first-order focusing are incompatible in a simple linear accelerator without foils or grids in the path of the particles. However, various attempts have been made to design more complicated field shapes and time variations that will circumvent this limitation. A general proof that the limitation exists in all cases was made by the author in 1945 but was not published at that time. This proof is given. A particle of charge e moves parallel to the z-axis with velocity v and is acted on by fields E and H, which are periodic in time and nearly periodic along the z-axis. The time period is T and the corresponding repeat length L is equal to vT. Changes in velocity and direction during one repeat length will be neglected; this is what they mean by the term 'first order'. The time corresponding to the position z is then given by t{sub o} + z/v, where t{sub o} is an arbitrary starting time. The focusing effect depends on the x and y force components F(subscript x) and F{sub y}, whose mean values are given by: {bar F}(subscript x) = (e/vT) {line_integral}{sub o}{sup L} [E(subscript x)-(V/c)H{sub y}] dz; and {bar F}{sub y} = (e/vT) {line_integral}{sub o}{sup L} [E{sub y} + (v/c)H(subscript x)] dz, the field components being evaluated at the position and correspond time of the moving particle. If the line of motion is chosen so that both these forces vanish, the restoring force constants toward this line are: k(subscript x) = -d{bar F}(subscript x)/dx; k{sub y} = - d{bar F}{sub y}/dy

The r-unit at 320 and 160 Mev by Edwin M McMillan( Book )
2 editions published in 1950 in English and held by 2 libraries worldwide
The r-unit is used today in at least two different ways: as a measure of radiation dosage, and as a measure of x-ray intensity. The meaning of the former is fairly well defined in terms of energy absorbed per gram of tissue, and the standard thimble chambers are calibrated to read in these terms. The meaning of the latter is much less clear. As originally defined, the r-unit referred to the ionization in air due to secondary electrons in equilibrium with the primary beam of x-rays. With low-energy x-rays equilibrium is easily attained since the range of the secondaries is small compared with the absorption distance of the primaries in air, but with high-energy-x-rays this is no longer true. Since a clearly defined equilibrium no longer exists, the old definition must be abandoned and the question remains: what should the r-unit mean in connection with the intensity of a beam of high-energy x-rays?
