Review of Scientific Instruments, 1948
The theory, design, and some experimental results relative to linear electron accelerators are discussed. It is shown that, though the orbits are unstable, this instability is so small as to be negligible in general, provided the electrons are injected at relativistic velocities. Likewise, space-charge spreading may be neglected.

Linear accelerator thalamotomy
Surgical Neurology, 2004The capability of performing functional radiosurgery lesions in the brain using a dedicated linear accelerator (LINAC) have not yet been demonstrated. This study evaluates modern LINAC technology for the creation of a sharp, small and functionally eloquent lesion in the thalamus.Three patients underwent thalamotomy using a dedicated linear accelerator ...

Linear Accelerator Radiosurgery
2008During the past decade, multiple linear accelerator (LINAC)-based radiosurgical systems have been developed. By measuring beam energy, beam accuracy, and dose gradient, it has been possible to demonstrate that these systems may compare favorably with the gamma knife. Clinical results also appear quite comparable in terms of efficacy and safety.

In this programme, we shall investigate problems of bodies which move under the direction of a force which is not constant. Also, we shall examine the problem of a body propelled by a constant force, but having a variable mass, such as a rocket. Remember the four equations of linear motion in Programme 1: $$ x = \tfrac{1}{2}\left( {{v_0} + v ...
