The second mid-term Objectives and Plan in the Plasma Research Center
On the basis of the 2nd mid-term objectives and plan of the University of Tsukuba and his support to the Bilateral Collaboration Research, our center is designated to be a nation wide collaborative center by the University and has dedicated it to the joint use of the facility among the nationwide universities, NIFS and other research institutes.
Along the line of the Report of the Fusion Research Working Group ( Jan., 2003) under the Bilateral Collaboration Research was started, which made our center to be nation wide joint research center from 2004. In the 2nd mid-term, we are going to push this line further and strengthen the collaboration.
In the 1st mid-term period, we challenged to study the physics of the confinement improvement by the electric potential and field, making use of the mirror advantages. We also challenged the development of the gyrotron, key tool for electron heating and potential control. These outputs have been regarded highly in the IAEA Fusion Energy Conference 2010.
Based on these outputs and precept, we will challenge to the urgent and indispensable issues of the Fusion Research which are appropriate in the era of the ITER construction and scope of the Fusion reactor prototype. We choose the two objectives, “Plasma transport control research” and “ boundary plasma control research by the divertor plasma simulator”, making use of the mirror advantage. Via these research, we are aiming for the harmonized co-existence of the high temperature core plasma (tens keV) and room temperature wall. One more research issue is the development of the gyrotron, key tool for these physics and material research. We will also contribute to the education and cultivation of the student and young scientists including ones outside university joined by the Bilateral Collaboration Research through these studies.
To make these research experiments, we are planning to renovate the GAMMA 10 device (GPDX: GAMMA10 Potential and Divertor eXperiment). One major change is to implement the divertor box in the mirror end section for efficient experiment using the heat and particle flux of the mirror throat. The other is introduction of the divertor coils for magnetic divertor experiment. The development of the MW gyrotron, key tool for the research, is also the major issue. Though we will face the great difficulties in challenging these big change and ambitious developments. We, the all the staff, will do best and hope your supports and encouragements.
