A Large Static Machine for X-Ray Work

A Simple Form of Influence Machine for X-Ray Work

To get X-rays out of a suitable vacuum tube, it needs to be excited by an electric discharge at a tension of hundreds of thousands of volts. Such a discharge is furnished by the induction coil and by the static induction or " influence" machine, associated in its most elegant and effective form with the name of Mr. Wimshurst. In spite of the obvious advantages of the latter type of machine over...

Optimum driving a Z-pinch for soft X-Ray lasers

A capillary plasma z-pinch as an alternative active medium of soft X-Ray lasers was studied experimentally and theoretically. The theoretical analysis was based on the self consistent solution of the so called “snow plow” model. The dynamics of pinched plasma is determined by the capillary parameters and by the time dependence of electrical current passing through it. The current time dependenc...

A Manual of Practical X-Ray Work

size of the book limits its scope. Nearly one-half of the book is devoted to a description of the various apparatus in use, and this section will be of the greatest value to beginners. The illustrations are ample and the individual apparatus are clearly described. There is also a good chapter on Photography. The localization of foreign bodies is dealt with in refreshingly simple language, and o...

HVL evaluation of orthovoltage X-ray machine using EGSnrc code of simulation

Background: Making use of the orthovoltage machines in Radiotherapy, is one of the routine methods for the treatment of the superficial lesions. In this study, an important determinant of X-ray quality, the HVL (Half Value Layer), has been evaluated. Materials and Methods: The HVLs of a orthovoltage X-ray machine in 120 and 180 kVp are measured, using an empirical method, in which the HVLs are ...
