TES-X-ray detector (1)■Superconducting Transition-Edge Sensor (TES) Calorimeter : X-ray detector■High energy resolution (dE~10-20 eV) in 0.1-10 keVcf. dE~200 eV for Si(Li)■Developed for X-ray astronomy to be mounted on Astro-E2■Ti/Au layer + SiN/Si base■Working at 0.1K; cooled by Adiabatic Diamagnetization Refrigerator (ADR)
GOALS: (AIST) Identification of high Z impurity lines and line free windows for Te measurement (JAXA, TMU) Test of the prototype detector using a real plasma source
SPEC.S: => see right
STATUS: Installation of the detector to TPE-RX has just started from Aug-3.
CMSO meeting, Madison, 6-August-2004AIST
TES-X-ray detector (2)Installed and cooled down in this week!: Aug. 3-5
Experiment will be done in Aug. 9-18.
First data Aug-5
CMSO meeting, Madison, 6-August-2004AIST
Helicity injection has started. Initial results are prommissing.
GOALS: Fuelling, Helicity injection (Current Drive), => Active control of the helicity, Current drive, Plasma biasing, Reconnection
SPEC.S: V=0.8kV, bias=3mWb, pulse=5ms, H~24mWb2
STATUS: Collaboration with Nihon Univ. & Hyogo Univ. Initial exp. showed an increase and sustainement of ne and a change of t

A common figure of merit representing the ‘self-organization’ may be needed. Change of free energy WF/WF0, Size scale? A new approach to understand a whole system may be needed.
