SIDDHARTA is a nuclear physics experiment aimed at the study of strong nuclear interactions using exotic atoms. This is achieved using monolithic arrays of Silicon Drift Detectors (SDDs), each consisting of eight SDD elements arranged in a 2×4 format (total area 18×34 mm2). A total of 48 SDD arrays arranged on a gantry structure are required to perform the experiment. Each SDD element is coupled to a CUBE pre-amplifier with the consequent shaping amplifier and complementary analog electronic stages implemented in a custom developed 16-channel SFERA chip. During the experiment, SDD arrays must be cooled down to cryogenic temperature below 120 K to perform X-ray spectroscopy to assess spread/shift of energy levels of exotic kaonic atoms. Alongside the cryogenic operation, the X-ray spectrometer needs to operate with a linearity of around 1 ± with an output stability of a few eV/day. This work describes the preliminary characterization results of cryogenically cooled 2×4 SDD arrays readout by SFERA chip. These include X-ray spectroscopy, stability and linearity performances.

ARDESIA is an SDD-based, multichannel X-ray spectrometer, optimized for synchrotron applications that require a high-count rate (> 1Mcps/channel) and high-resolution (<130eV of FHWM Mn-Kα line at optimum shaping time, ≤200eV at short shaping times) X-ray fluorescence detection. The main applications of the ARDESIA detector are X-ray fluorescence (XRF) and X-ray absorption fine structure (XAFS) techniques. The detector is based on a monolithic array of 4 SDD with 25mm2 active area (collimated to 16mm2) each, which optimizes detector solid angle. After the optimization of the 4-channels detection module, the mechanical structure grants cooling, with a double Peltier strategy, vacuum, insulation from the harsh surrounding environment and possibility to place side-by-side several SDD modules to realize a larger number of channels. The detector signals are amplified by a monolithic four-channels CUBE preamplifier chip and processed by digital pulse processors (e.g. XGLab-DANTE, 4-channel XIA DXP-XMAP) to achieve good energy resolution at high count rates. Successful campaign of measurements at the DAΦNE DXR1 soft X-ray beamline in Frascati, Italy and ESRF LISA BM-08 beamline in Grenoble, France, such as XRF measurements in soft x-ray energy range, and long-duration consecutive XAFS measurements using various samples, confirm the qualification and performance of the instrument, in terms of energy resolution, throughput capability, immunity against external disturbances, and stability.
