D2R1 (Dimension 2 revision 1) is the most recent development of CdTe based X-ray detectors within a series of highly successful imaging spectrometers CALISTE. The detector consists of a CdTe crystal which is directly connected to a low-noise readout ASIC by a flip-chip bonding process. The reduced stray capacitance in combination with an adapted ASIC design results in a superior energy resolution of 584 eV FWHM at 60 keV. The 16x16 pixel array with a 300um pixel pitch constitutes a 4.8x4.8 mm^2 detector surface on a 750um thick crystal. Such fine-pitched hard X-ray detectors show not only an improved spatial resolution but also an improved spectral resolution at soft and medium energies. A slightly diminishing spectral resolution is only observed for energies that are large enough to increase the split ratio significantly. X-ray polarimetry based on incoherent scattering also benefits from the improved spectral and spatial resolution. Furthermore, the sensitivity for polarimetric measurements that uses only a single detector unit is greatly enhanced because of an increased efficiency for detecting Compton scattered events: within smaller pixel structures, the position of the incoherent scattering and the position of the scattered photon absorption are less likely within the same pixel and can be therefore detected individually. After a description of the new ASIC concept we are presenting laboratory measurements that were realized with several different detector modules in order to verify their spectral and spatial properties. The home made ASIC of D2R1 is based on a Charge Sensitive Amplifier (CSA) in combination with a Multi Correlated Double Sampling method: the continuous sampled outputs of the CSA are averaged on -chip before and after an event detection. The difference of these two values represent the signal height of the detected event. The ASIC exhibit very good performance and the Equivalent Noise Charge is as low as 29 electors rms, making them perfectly suitable to read semiconductor detectors of any kind and any bias polarity. In order to investigate the spectral and spatial properties the focus of the data analysis is put on the event split ratio and its dependence with energy. The determination of the virtual pixel size for single events, i.e. the region within a pixel that results in a single event detection, is key for a proper understanding of the evolution of the spectral and spatial resolution with energy. While split events decrease the spectral performance because of added noise contributions of multiple readout channels, they increase the spatial resolution by allowing a center-of-mass calculation with a sub-pixel resolution. The virtual pixel size for single, double, triple, and quadruple events are estimated with an analytical model which is verified by measurements at different energies (5.6 keV, 13.9 keV, 60 keV, 122 keV and 245 keV). Finally, the polarimetric performance of D2R1 is examined via detailed simulations. The wide accessible energy range between 2-250 keV and the fast timing capabilities complete D2R1 to suite a variety of different applications. Excellent spatial, spectral, and timing capabilities in the medium and hard X-ray range are key parameters for future X-ray missions. All these properties are well combined within the D2R1 concept.

In the frame work of the ESA Euclid mission to be launched in 2020, the Euclid Consortium is developing an extremely large and stable focal plane for the VIS instrument. After an extensive phase of definition and study over 4 years made at CEA on the thermo-mechanical architecture of that Focal Plane, the first model (Structural and Thermal Model) has been assembled qualified and delivered to MSSL in June 2017. The VIS Focal Plane Assembly integrates 36 CCDs (operated at 150K) connected to their front end electronics (operated at 280K). This Focal Plane will be the largest focal plane (~0.6 billion pixels) ever built for space application after the GAIA one. The CCDs are CCD273 type specially designed and provided by the Teledyne e2v company under ESA contract, front end electronics is studied and provided by MSSL. The Structural and Thermal Model is fully representative of the Flight Model regarding the thermo-mechanical architecture. As the instrument development philosophy follows a Proto Flight approach this choice has been made very early in the development program in order to reduce the risk on the PFM program. So the AIT/AIV plan has been built in order to fully validate since the STM program the overall integration, verification and qualification sequences, taking into account the very stringent cleanliness requirement. The STM FPA integrates 36 CCDs representative of the flight model except for the detection function. Electrical configuration of the front end electronics provides electrical interface in order to power the CCDs and check integrity of all the electrical links to CCDs. In this paper we first recall the architecture of the VIS-FPA and especially the solutions proposed to cope with the scientific needs of an extremely stable focal plane, both mechanically and thermally leading to a SiC structure. The modular architecture concept, considered as a key driver for such big and complex focal plane is detailed. Parallel to that, the integration workflow including verification steps is fully depicted including specific aspects linked to the use of SiC. Validation and qualification test program is described. A summary of geometrical measurements, thermal balance tests and vibrations tests including the main Ground Support Equipment description are reported.
