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 ...

Computer interface for a linear accelerator
Medical Physics, 1980A computer interface for the Clinac‐18 linear accelerator has been developed, using a standard CAMAC interface plus buffer amplifiers to isolate the CAMAC from the accelerator electronics. Buffer amplifiers are employed because direct connection of the CAMAC system to the accelerator was found to affect accelerator operation.

Acceleration of Linear and Logarithmic Convergence
SIAM Journal on Numerical Analysis, 1979Eleven different methods for accelerating convergence of sequences and series have been tested and compared on a wide range of test problems, including both linearly and logarithmically convergent series, monotone and alternating series. All but one of these methods are already in the literature, and they include both linear and nonlinear methods.

“HORNS” on a 6Mev linear accelerator
International Journal of Radiation Oncology*Biology*Physics, 1981Abstract Measurements made of the in-air off-axis ratios (OARS) on a very recently installed 6MeV linear accelerator revealed a maximum OAR of 1.23 at 16 cm from the central axis at 100 cm source-axis distance (SAD); at the same time, standard beam uniformity specifications (at 10 cm depth) were satisfied.
