End-on soft x-ray imaging of Field-Reversed Configurations (FRCs) on the Field-Reversal-C (FRX-C)/ Large Scale Modification (LSM) experiment

PDF Version Also Available for Download.

Description

Recently, a prototype soft X-ray pinhole camera was fielded on FRX-C/LSM at Los Alamos and TRX at Spectra Technology. The soft X-ray FRC images obtained using this camera stand out in high contrast to their surroundings. It was particularly useful for studying the FRC during and shortly after formation when, at certain operating conditions, flute-like structures at the edge and internal structures of the FRC were observed which other diagnostics could not resolve. Building on this early experience, a new soft X-ray pinhole camera has been installed on FRX-C/LSM, which permits more rapid data acquisition and briefer exposures. It will ... continued below

Description

Recently, a prototype soft X-ray pinhole camera was fielded on FRX-C/LSM at Los Alamos and TRX at Spectra Technology. The soft X-ray FRC images obtained using this camera stand out in high contrast to their surroundings. It was particularly useful for studying the FRC during and shortly after formation when, at certain operating conditions, flute-like structures at the edge and internal structures of the FRC were observed which other diagnostics could not resolve. Building on this early experience, a new soft X-ray pinhole camera has been installed on FRX-C/LSM, which permits more rapid data acquisition and briefer exposures. It will be used to continue studying FRC formation and to look for internal structure later in time which could be a signature of instability. This paper summarizes the initial operation of this camera. 2 refs., 6 figs.
