A large array of silicon microcalorimeters for storage ring experiments — •Saskia Kraft-Bermuth1, Victor Andrianov2, and Pascal Scholz1 — 1Justus-Liebig-Universität, Gießen, Germany — 2Lomonosov Moscow State University, Moscow, Russia
Silicon microcalorimeters have already demonstrated the potential to considerably improve the experimental accuracy for X-ray experiments at heavy ion storage rings. To improve their performance with respect to statistical as well as systematic uncertainties, a large array of silicon microcalorimeters for high-precision X-ray spectroscopy, especially optimized for experiments at storage rings, has now been designed. In particular, the large dynamic range will allow the intrinsic determination of the Doppler correction, which is a prominent source of systematic uncertainty in such experiments. The contribution will present the design of the new detector array as well as the readout and data acquisition system. In addition, vibration studies of the cryogen-free dilution refrigerator will be presented.
