X-ray PIN, diodes fitted with different transmission filters, were employed to detect the X-radiation in different energy bands. The comparison of the relative intensities in each band gives a time-resolved measurement of the electronic temperature. The method consists in applying a simple model of the continuum spectrum that is convoluted with the filter-detector response to obtain predicted amplitude ratios.

La utilización de detectores de rayos X provistos de diferentes filtros permite detectar la radiación en varias bandas de energía. Mediante la comparación de las intensidades en las diferentes bandas se puede estimar la temperatura electrónica. El método se basa en la convolución de la respuesta de los detectores y el espectro continuo de emisión de un plasma para predecir una respuesta.
