Development of X-ray calorimetric detectors and data processing techniques at London University

The authors describe research in progress in which they have designed and constructed thermal detectors which are capable of measuring the small pulses of energy produced by the absorption of X-rays in the 1 - 10 keV energy range. At present these detectors are operated at 3He temperature (0.34K), which results in an inherent energy resolution of 673 eV. The authors also present a preliminary discussion on the possible processing techniques that can be applied to the raw data; such processing improves the achievable resolution to around 350 eV
