In this article, the measurement system for the total radiation and electron temperature profiles to be installed in a reversed-field pinch machine, toroidal pinch experiment, RX [TPE-RX, R/a=1.72/0.45 m, Ip<MA (designed)], is presented. We plan to measure the plasma radiation and electron temperature profiles using three sets of diode arrays. Each array can measure radiation along 20 lines of sight and the radial profile of the radiation. One set of the arrays is used for the bolometric measurement in the range from visible light to soft x-ray. Two sets of the arrays are used for the soft-x ray and electron temperature measurements employing a double-filter method. We will use this system to investigate the plasma-wall interaction, radiation loss, and confinement properties in the core plasma region. We will extend the use of this system for tomographic analysis of electron temperature, a concept of which is also presented.
