Abstract
We present an overview of recent work on the micro-calorimeter at the Shanghai EBIT laboratory. The micro-calorimeter was established under a collaboration between the Shanghai EBIT laboratory and the Smithsonian Astrophysical Observatory. The first micro-calorimeter spectra of Ar XVII/XVIII from the Shanghai EBIT have recently been obtained. In our case, amplitude drift correction had to be made in order to get decent spectral resolution. The resolution at 3keV is about 20eV. The reason why the resolution is not as good as during offline tests (13eV) is thought to be due vibrations from the Shanghai EBIT, to which it is directly connected via a stainless steel tube.
