Linear accelerators for high energies

Calculation the phantom scatter factor for the linear accelerators device

Introduction: In the last few decades, a lot of monte carlo codes have been introduced for medical applications. this is important because through simulation, we are fully independent of the spectral scattering factor that we are not able measure in real terms. The effect of the radiation energy, the dimension of the radiation field, the sensitive volume of the ion chamber on t...

Travelling Wave Linear Accelerators

Communicated b y y. D. Cockcroft; MS. ABSTRACT. Acceleration of electrons by means of an electroma,onetiic wave travelling down a circular corrugated tube is considered. The relevint properties of corrugated tubes are derived and the factors influencing electron enxgies. Some numerical results are also quoted for a wavelength of 10 cm. The problems of high energy accelerators arc &scussed brief...

High-Gain Free Electron Lasers Using Induction Linear Accelerators

High-power free electron lasers (FEL’s) can be realized using induction linear accelerators as the source of the electron beam. These accelerators are currently capable of producing intense cwrents (102-104 A) at moderately high energy (1-50 MeV). Experiments using a 500 A, 3.3 MeV beam have produced 80 MW of radiation at 34.6 GHz and are in good agreement with theoretical analysis. Future expe...

Resonances and Envelope Instability in High Intensity Linear Accelerators

Understanding of space charge effects has grown and recent studies have led to the findings of space charge resonances in high intensity linear accelerators. Lately the sixth order resonance of high intensity linear accelerators was reported, along with the in-depth studies on the interplay of the fourth order resonance and the envelope instability. Experiment studies on space charge resonances...
