Abstract :
Using a magnetic calorimeter, we have obtained an energy resolution of 13 eV in the detection of 6 keV X-rays. The calorimeter consisted of a 50 μm diameter, 25 μm thick Au sensor doped with 300 ppm Er. A 100×100 μm square, 8 μm thick Au absorber was attached to the sensor. At the operating temperature of 33 mK and with a field of 3 mT, the calorimeter had a heat capacity of 1.3×10−12 J/K. With a magnetic calorimeter optimized for X-ray detection an order of magnitude improvement in resolution should be possible.
