Density Collapse in Improved Confinement Mode on Tohoku University Heliac

The density collapse was observed in the improved confinement mode sustained by the hot cathode biasing in Tohoku University Heliac (TU-Heliac). The density profiles showed the steep gradient around the core plasma region before the collapse. The steep density profile collapsed accompanied with the bursting high frequency fluctuation (100 < f < 500 kHz), which had m = 2 ~ 3 poloidal mode number...

Design of a synchrotron radiation source at Tohoku University.

The construction of a third-generation light source has been proposed at Tohoku University. The emittance is 7.3 nm rad at the nominal beam energy, 1.5 GeV. The circumference is 194 m. The ring consists of 12 double-bend achromatic cells. Ten of 12 dispersion-free long straight sections are 5 m long and will be used for insertion devices and some accelerator components. The remaining two are ea...

Development of Micromachine Gas Turbines at Tohoku University

Development of micromachine gas turbines is underway at a group lead by Tohoku University in Japan. The goal is to develop a light-weight power source to replace the heavy batteries that may limit the progress of humanoid robots. Internal combustion engines have advantages of both high power density and high energy density, so it can be the best choice for the power source for mobile machines. ...

Recent great impact by an Isotope Separator On-Line (ISOL) in nuclear and radiochemistry.

On April 9 2015, the Letter article titled "Measurement of the first ionization potential of lawrencium, element 103" is now published at News and Views on Nature (2015) which has been performed by our remarkably Japanese colleagues of nuclear and radiochemistry at JAEA (Japan Atomic Energy Agency). In this review, the author will state that the isotope separator on-line (ISOL) our regularly us...
