introduction: nowadays new radiochromic films have an essential role in radiotherapy dosimetry. properties such as high sensitivity, good reproducibility, high spatial resolution, easy readout and portability have made them attractive for dosimetry, especially in high-dose-gradient regions. material and methods: in this study, electron-beam dose distributions in homogenous and heterogeneous pha...
The need to produce intense X-rays in the Energy Recovery Linear Accelerator requires shorter and narrower electron beams than the Cornell Electron Storage Ring can provide. Such electron beams will demand highly accurate beam position monitors (BPMs) to enable operators to control the beam. To prepare for new BPMs, a test stand has been built to conduct experiments on new algorithms and design...
Abstract When spin rotating devices are used in an electron accelerator ring the stochastic depolarization caused by synchrotron radiation becomes issue. Special design of optics is required order to minimize harmful effect depolarization. Ring adjustments which help called matching. In this lecture formalism for deriving matching conditions presented. Then, derived examples a rotator based on ...
The Cornell Electron Storage Ring (CESR) has been reconfigured as an ultra low emittance damping ring for use as a test accelerator (CesrTA) for International Linear Collider (ILC) damping ring R&D [1]. One of the primary goals of the CesrTA program is to investigate the interaction of the electron cloud with low emittance positron beam to explore methods to suppress the electron cloud, develop...
The proposed future International Linear Collider (ILC) will collide electrons and positrons. Because positrons are antimatter, they are harder to produce than electrons and need to be accumulated and conditioned in a damping ring. The Cornell Electron Storage Ring Test Accelerator (CesrTA) at the Cornell Laboratory for Accelerator-based Sciences and Education (CLASSE) is similar to the damping...
The present development of the accelerator part of the MAX IV synchrotron radiation project is presented. The main features of the 3 GeV injector linac and the two storage rings operated at different electron energies to cover a broad spectral range of high brilliance undulator radiation are described in some detail. A third ring, the existing MAX III ring is planned to be transferred to the ne...
