چکیده

nen zur Entladungsachse hin konzentriert. Damit wäre eine Abweichung des Dichteprofils von der BESSELschen Form Gl. (13) verbunden, die sich entlang der Entladung bis zur Anode wieder ausgleicht. Das schärfere Dichteprofil hätte niedrigere Dichtegradienten am Rand und damit geringere Verluste im geraden Teil zur Folge; die daraus resultierende niedrigere elektrische Längsfeldstärke würde zu einem höheren Bc gegenüber dem der Anode näheren Teil der Entladung führen. Wir sehen, daß dieses Bild die experimentellen Resultate qualitativ erklären könnte. Die endgültige Entscheidung zwischen 3., 4. und 5. c) kann erst eine verfeinerte theoretische und experimentelle Analyse der zur Torusdrift führenden elektrischen Radialfelder und Dichteprofile, eine Erweiterung des Gültigkeitsbereiches der Theorie durch weitere Erhöhung von Bc sowie eine Untersuchung der Verluste bei Richtungsumkehr der longitudinalen elektrischen Feldstärke bringen, was einer späteren Arbeit vorbehalten sein soll.

Assessment of an Unshielded Electron Field Diode Dosimeter for Beam Scanning in Small- to Medium-Sized 6 MV Photon Fields

Introduction Radiotherapy planning systems require many percentage depth dose (PDD) and profile measurements and there are various dosimeters that can be used to obtain these scans. As dose perturbation is particularly troublesome in smaller photon fields, using a low-perturbation, unshielded electron field diode (EFD) in these fields is of interest. The aim of this work was to investigate the ...

Comparison of Electron-Beam Dose Distributions in a Heterogeneous Phantom Obtained Using Radiochromic Film Dosimetry and Monte Carlo Simulation

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...

Foil-less plasma-filled diode for HPM generator

Plasma-filled diode regarded as perspective source of electron beam feeding HPM generator of GW power level, comparing to conventional explosive emission vacuum diode. Electron beam generation occurs in plasma double layer, where plasma boundary plays as an anode. It allows cancelling the usage of anode foils or grids in HPM generators with the virtual cathode, which could limit its life time t...

Laser diode optically pumped caesium beam

2014 This paper presents a theoretical analysis of a possible scheme to realize a strong population difference between the two ground state sub-levels F = 4, MF = 0, and F = 3, MF = 0 of caesium atom. Two laser-diode light beams, 03C0 polarized, are used to illuminate at right angle an atomic beam. The efficiency of the population difference build up is evaluated for two limiting cases accordin...

Caesium influence on plasma parameters and source performance during conditioning of the prototype ITER neutral beam injector negative ion source

Systematic Langmuir probe measurements were performed during the caesium (Cs) conditioning of the IPP prototype negative hydrogen ion source. Conditioning consists of slowly injecting caesium into the source in order to increase the extracted negative ion current and minimize the co-extraced electrons. This process usually takes several days. Measurements were taken near the plasma grid where t...
