Emission Performance of a Slit Type Caesium Field Ion Source
نویسنده
چکیده
Results are reported of a study of the emission performance of a slit type liquid caesium field ion source which oriqinally was developed by the European Space Research and Technology Centre a s an ion thruster for electric space propulsion. The emission site distribution and the ion beam divergence are examined a s a function of the wetting properties at the emitter slit edge.

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...
متن کاملCaesium sputter ion source compatible with commercial SIMS instruments
A simple design for a caesium sputter cluster ion source compatible with commercially available secondary ion mass spectrometers is reported. This source has been tested with the Cameca IMS 4f instrument using the cluster Sin and Cun ions, and will shortly be retrofitted to the floating low energy ion gun (FLIG) of the type used on the Cameca 4500/4550 quadruple instruments. Our experiments wit...
متن کاملInitial study of the optical spectrum of the ISIS H- ion source plasma.
The front end test stand is being constructed at the Rutherford Appleton Laboratory, with the aim of producing a 60 mA, 2 ms, 50 Hz, perfectly chopped H(-) ion beam. To meet the beam requirements, a more detailed understanding of the ion source plasma is required. To this end, an initial study is made of the optical spectrum of the plasma using a digital spectrometer. The atomic and molecular e...
متن کاملPerformance Improvement of Field Effect Diodes (FED) for Nanotechnology
One of the main problems of field effect diode (FED) is the increasing of its turn-off current as the channel length decreases. Thus, in this paper, a new structure is presented which decreases the injection of extra carriers to the channel and also increases the control of the gate over the channel by reducing the portion of channel shared with the source and drain regions and without the need...

Introduction: Myocardial perfusion SPECTby 99mTc-Sestamibi and 99mTc-Tetrofosmin radiopharmaceuticals usually presents a false significant increase in the radiotracer uptake in the inferior myocardium due to the uptake in organs such as liver, bowel, stomach and biliary system. The present study evaluated a suitable Slit angle for differentiating extra-car...
