Accelerator Optimization through Beam Diagnostics
A comprehensive set of beam diagnostics is key to the successful operation and optimization of essentially any accelerator. The oPAC project received 6 M€ of funding within the EU's 7th Framework Programme. This has allowed to successfully train 23 Fellows since 2011. The network joins more than 40 institutions from all around the world, including research centers, universities and private comp...
متن کاملContinuous Electron Beam Accelerator Facility,
We use local quark-hadron duality to estimate the purely nonperturbative soft contribution to the γ * p → ∆ form factors. Our results are in agreement with existing experimental data. We predict that the ratio G * E (Q 2)/G * M (Q 2) is small for all accessible Q 2 , in contrast to the pQCD expectations that G * E (Q 2) → −G * M (Q 2).
متن کاملRelativistic Klystron Two-Beam Accelerator*
Relativistic klystrons are being developed as an rf power source for high gradient accelerators applications which include large linear electronpositron colliders, compact accelerators, and FEL sources. In a relativistic klystron two-beam accelerator (RK-TBA), the drive beam passes through a large number of rf output structures. High conversion efficiency of electron beam energy to rf energy ca...
متن کاملDesign and dosimetry characteristics of a commercial applicator system for intra‐operative electron beam therapy utilizing ELEKTA Precise accelerator
The design concept and dosimetric characteristics of a new applicator system for intraoperative radiation therapy (IORT) are presented in this work. A new hard-docking commercial system includes polymethylmethacrylate (PMMA) applicators with different diameters and applicator end angles and a set of secondary lead collimators. A telescopic device allows changing of source-to-surface distance (S...
متن کاملAdvances in kilovoltage x-ray beam dosimetry.
This topical review provides an up-to-date overview of the theoretical and practical aspects of therapeutic kilovoltage x-ray beam dosimetry. Kilovoltage x-ray beams have the property that the maximum dose occurs very close to the surface and thus, they are predominantly used in the treatment of skin cancers but also have applications for the treatment of other cancers. In addition, kilovoltage...
