چکیده
Ray optics and phase ellipse Optics are developed as tools for designing charged particle beam guidance systems. Specific examples of basic optical systems and of phase ellipse matching are presented as illustrations of these mathematical techniques. Presented at the Conference on Charged Particle Optics Giessen, West Germany September 8-12, 1980 also submitted to Nuclear Instruments and Methods * Work supported by the Department of Energy, contract DE-AC03-76SF00515.

Optimum Operation of Split Rf Photoinjectors
We. describe how to achieve minimum transverse emittance in RF photoinjectors by applying theoretical predictions from a fully analytical model of beam dynamics in a split injector. This device consists of a short two cell (full+partial) RF gun followed by a drift and a booster RF linac. Matching the beam in the booster to the invariant envelope, an equilibrium mode of laminar beam flow, is sho...

متن کاملAccuracy of Image Guidance Using Free-Breathing Cone-Beam Computed Tomography for Stereotactic Lung Radiotherapy
Movement of the target object during cone-beam computed tomography (CBCT) leads to motion blurring artifacts. The accuracy of manual image matching in image-guided radiotherapy depends on the image quality. We aimed to assess the accuracy of target position localization using free-breathing CBCT during stereotactic lung radiotherapy. The Vero4DRT linear accelerator device was used for the exami...
متن کاملABCD matrix for reflection and refraction of laser beam at tilted concave and convex elliptic paraboloid interfaces and studying laser beam reflection from a tilted concave parabola of revolution
Studying Gaussian beam is a method to investigate laser beam propagation and ABCD matrix is a fast and simple method to simulate Gaussian beam propagation in different mediums. Of the ABCD matrices studied so far, reflection and refraction matrices at various surfaces have attracted a lot of researches. However in previous work the incident beam and the principle axis of surface are in parallel...
متن کاملReduction of Transverse Emittance Growth along the UNILAC
The preservation of beam quality along the UNILAC Alvarez DTL section is a major concern with respect to the availability of the design beam parameters for FAIR. The DTL comprises 177 accelerating gaps and 184 quadrupoles for transverse beam focusing. They form a periodic structure of linear elements. The high beam currents needed for FAIR arise non-linear space forces leading to emittance grow...
