Time Evolution of Plasma Potential in Pulsed Operation of Ecris*
نویسندگان
چکیده
The time evolution of plasma potential has been measured with a retarding field analyzer in pulsed operation mode with electron cyclotron resonance ion sources at JYFL and RIKEN. Three different ion sources with microwave frequencies ranging from 6.4 to 18 GHz were employed for the experiments. The plasma potential was observed to increase 10-75 % during the preglow and 10-30 % during the afterglow compared to steady state.

Charge State Boosters for Radioactive Ion Acceleration
For the post acceleration of radioactive ions produced at ISOL facilities the increase of the charge state is essential to fulfill the A/q requirements of the accelerators. Many of those existing or proposed facilities are relying on the performance of charge state boosters of EBIS or ECRIS type. Although, in principle both types of sources can be used in pulsed or continuous mode operation an ...

Electron Cyclotron Resonance Ion Sources (ECRIS) have been developed for long time and performances are still extended at present. Recently, they are not only used in producing multi-charged ions, but also molecules and cluster ions. A new type of ion source with a wide operation window is expected for various uses. We developed a novel magnetic field configuration ECRIS. The magnetic field con...

The ECLISSE experiment proved in 2002 the possibility to couple a Laser Ion Source (LIS) with an Electron Cyclotron Resonance Ion Source (ECRIS) in order to obtain ion beams from refractory metals with a cw beam structure. The use of a LIS inside the ECRIS plasma chamber may permit to increase the beam current and the ion charge state. The use of 3 generation ECRIS may extend the capabilities o...
متن کاملDesign Study of a Higher-magnetic-field Sc Ecris at Imp
Development of ECR ion source has demonstrated that, as the empirical scaling laws summarized, higher magnetic field with higher operation frequency will greatly improve the source performance. Based on the great success of SECRAL at IMP, a higher-magnetic-field SC ECRIS is planned to meet the new accelerator demands. However, there are many practical issues in the design and construction of a ...

ABSTRACT: The combination of pulsed vacuum osmotic dehydration and microwave drying of garlic bulbs were examined. The response surface methodology (RSM) was used to determine the effect of NaCl concentration (8%-20%), osmotic solution temperature (25-65°C), operation pressure (240-830 mbar), immersion time (20-300 min) and microwave power level (100-600 W) on water loss (WL), solids gain (SG),...
