Helical Fusion marks milestone in progress toward fusion power
Helical Fusion, a Japan-based fusion start-up that is developing a stellarator fusion power reactor, has announced it has successfully demonstrated its high-temperature superconducting (HTS) coil under relevant magnetic conditions.
A video highlighting the stellarator’s technology testing can be found here.

The neutral transport was studied in the anchor cell. The H line intensities were measured by using axially aligned H detectors. It was found that the intensity is considerably dependent on ECRH and GP#3,4. A 5ch H detector was newly installed in the outer-transition region of the anchor-cell. From the measurement of the spatial distributions, the vertical intensity profile is estimated to be about 2.5 cm on the half width half maximum, while the horizontal distribution shows roughly flat around Z=-670 cm. The above characteristics were discussed with aid of neutral transport simulation using DEGAS Monte-Carlo Code.
