TL;DR: In this article, a soft x-ray tomography system for the RTP tokamak is presented, where five pinhole cameras are distributed inside the vessel in such a way that it becomes possible to reconstruct modes up to m = 4 without making any assumption about the plasma rotation.
Abstract: A soft x‐ray tomography system is being constructed for the RTP tokamak. The main aim of this system is to measure fluctuations in the plasma emissivity with relatively high poloidal m number. Five pinhole cameras will be distributed inside the vessel in such a way that it becomes possible to reconstruct modes up to m=4, without making any assumption about the plasma rotation. The system has been designed to obtain a minimum bandwidth of 200 kHz and a temporal resolution of 1 μs. We describe the hardware that is under construction.
