摘要：

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 mu m diameter, 25 mu m thick Au sensor doped with 300 ppm Er. A 100 x 100 mu m square, 8 mu m thick Au absorber was attached to the sensor. At the operating temperature of 33 mK and with a held of 3 mT, the calorimeter had a heat capacity of 1.3 x 10(-12) J/K. With a magnetic calorimeter optimized for X-ray detection an order of magnitude improvement in resolution should be possible. (C) 2000 Elsevier Science B.V. All rights reserved.
