In order to measure the fast ion using NPAs in the low neutral density core region of a magnetic confinement fusion device, active change exchange measurements are often performed using a NB as a CX target

Development of Rogowski probe for internal plasma current measurement in the collisional merging process of field-reversed configurations

October 2022 | J. Ogasawara (Nihon) | Review of Scientific Instruments | Paper

To directly detect the spatial distribution of a plasma current during the collisional merging of two FRCs in the FAT-CM device, an internal current probe using Rogowski coils has been developed.
