在JYFL开展的研究工作：等离子体势的测量、电子加热的模拟、JYFL-MMPS及高温炉子(英文)

摘要

Extensive plasma potential measurements have been carried out using a device developed at JYFL. In this article the main results of the measurements will be summarized.A new simulation code to study the electron heating is being developed.One objective of the code is to determine the change of the electron loss cone when the magnetic field component of the electromagnetic wave is taken into account along with the permittivity of the plasma.As a part of the work,accurate X-ray measurements have been initiated. A new plasma chamber based on the MMPS-concept(Modified MultiPole Structure)has successfully been constructed and tested with the JYFL 6.4GHz ECRIS.The results and conclusions will be presented elsewhere in these proceedings.In the same article,a new concept of ECRIS and first results will be presented.The active development work of evaporation ovens has been carried out in a joint European collaboration(ISIBHI). The objective of the task is to make the operation of the oven reliable at 2000℃for several days.Both resistively and inductively heated ovens have been studied and further developed.The status of this work will be presented.
