We describe experiments to characterise the responsivity of superconducting tunnel junction (STJ) X-ray detectors in which the absorbed photons were simulated by heat pulses. Independent values of tunnel and loss times could be inferred from the time variation of the STJ current, whilst its integration gave the total charge output. The effects of self-recombination and trapped magnetic flux could also be determined. Results were obtained at 1.3 K for a Nb STJ, and at 20 mK for a Ta device.
