Effects of Alternating Cell Misalignments on the DDS
نویسنده
چکیده
We study some effects of cell misalignments in accelerator structures in which each cell is displaced the same amount and direction but with sign which alternates from cell to cell. In particular we study the manifold radiation in a damped detuned structure (DDS1) and wakefield effects in a uniform constant impedance structure. A synchronous wave aliasing phenomenon is observed. In previous treatments the effect of cell misalignment has been modeled by replacing it by beam displacement. Here we compare finite difference simulation of cell misalignment with the beam displacement model. We conclude with discusions about the relevance of our results for general misalignment profiles.

Analysis And Application Of Manifold Radiation In DDS 1 : First Experiences 1
The cells in the SLAC DDS are designed in such a way that the transverse modes excited by the beam are detuned in a Gaussian fashion so that destructive interference causes the wake function to decrease rapidly and smoothly. Moderate damping provided by four waveguide manifolds running along the outer wall of the accelerator is utilised to suppress the reappearance of the wake function at long ...
متن کاملInduced tissue cell death by magnetic nanoparticle hyperthermia for cancer treatment: an in silico study
In this paper, we simulate magnetic hyperthermia process on a mathematical phantom model representing cancer tumor and its surrounding healthy tissues. The temperature distribution throughout the phantom model is obtained by solving the bio-heat equations and the consequent cell death amount is calculated using correlations between the tissue local temperature and the cell death rate. To have a...

This study introduced a method based on magnetic field assisted finishing mechanism for micromachining the inner surfaces of Aluminum tubes. In this approach, using the alternating magnetic field of an AC electromotor, abrasive particles were formed as Magnetic Rods (Magnetic Clusters) and surface micromachining was carried out by the dynamic particular pattern made by an alternating magnetic f...

Background: Pre-op anxiety has adverse effects on the patientchr('39')s anesthesia and treatment. Currently, electrical interventions are widely used as non-invasive methods to control pre-op anxiety and may have advantages as compared with medical therapies. This study aimed to determine the effect of transcranial alternating current stimulation on anxiety and hemodynamic response of patients ...
متن کاملSteroid-sparing effect and toxicity of dapsone treatment in giant cell arteritis
Although a glucocorticoid (GC)-sparing strategy is needed for patients with giant cell arteritis (GCA) suffering from refractory disease or serious treatment-related complications, evidence of efficacy in this setting of immunosuppressive drugs and biotherapies is lacking. Herein, we evaluated the GC-sparing effects and tolerability of addition of dapsone (DDS) to prednisone therapy in patients...
