PPT-W. Wuensch 8-9-2012 High-Gradient Accelerating Structures for Proton Therapy Linacs

Significant progress has been made over the past decade by studies of normalconducting linear colliders NLCJLC and CLIC to raise achievable accelerating gradient from the range of 2030 MVm up to 100120 MVm . 1 The Proton Gradient Drives ATP SynthesisThe electrochemical proton gradient across the inner mitochondrial membrane is used to drive ATP synthesis in the process of oxidative Phosphorylation. The de The flow of electrons from NADH and FADH. 2. to O. 2. occurs in the electron-transport chain or respiratory chain..

Laboratory of Nuclear Problems, JINR, the Medico-Technical Complex (MTC) was developed on the basis of the 660-MeV proton accelerator (. phasotron. ), where patients with different tumors are treated using 3D conformal proton beam therapy which allows the dose distribution maximum to be shaped so as to most closely match the shape of the irradiated target. The dose drastically falls off beyond the tumor boundaries, which allows treatment of earlier inaccessible localizations immediately adjacent to a patient’s vital radiosensitive .
