European Space Agency detector development for space science: present and future activities

We report on the present and future detector development activities for the European Space Agency Science Programme. The development of European technology in that field is a key mission enabler for the program, which requires TRL6 (ISO scale) by end of the definition phase, so called "mission adoption". This is particularly true for Astronomy and fundamental physics type missions. Current activities are in particular targeting large format and p-channel CCD, NIR and MWIR, LWIR wavelength ranges as well as related ASIC controller. For the longer term future mission plan (so called M4, M5 and L2 missions, M3 being PLATO and L1 JUICE), the extreme ends of the spectrum will be addressed. An overview of the detector status for the Earth Observation program is given in appendix, as most of the technologies are directly applicable to some extent to science missions, in particular for Planetary missions. The specific validation activities in place in the future mission preparation office in support to the space science program will be eventually briefly detailed.

“…The BIRA-IASB facility uses a closed-cycle cryostat with one single cold head to thermalize the detector and the radiation shield at cryogenic temperatures. Some facilities, such as Crouzet et al 28 and Biesiadzinski et al, 22 still prefer the use of open-cycle cryostats mainly due to the absence of vibrations from the pumping and cryogenic systems that can affect the stability of the detector under test. The clear disadvantage is the periodic refill of the cryostats unless it is performed automatically, as in Weatherill et al 21 This is not an issue for the BIRA-IASB facility, since the detector mount was mechanically designed to compensate for any vibration from the cryogenic system.…”

“…22,27 Operating CCD or CMOS detectors at near-infrared (NIR) and even visible wavelengths require their thermalization at cryogenic temperatures. Open-cycle cryostats are used in some characterization facilities 20,21,28 to reach these temperatures. Vibrations in such systems would only come from the pumping system, which is normally disabled during measurements.…”

When developing new astronomical instruments, there is a need to perform the characterization of their individual components, especially the detectors, to ensure that their performances comply with the scientific objectives of the instrument. A visiblenear infrared (VIS-NIR) facility was developed for the absolute and relative radiometric characterization of space-based detectors at the Royal Belgian Institute for Space Aeronomy (BIRA-IASB). The facility operates from 0.4 to 2.65 μm in an ISO-5 environment. It offers a tunable monochromatic flux with a high level of straylight rejection (10 −8 ) and 2% uniformity, over a four-decade range of intensity with adjustable bandwidth. Latency measurements are also possible. Thermalization is offered within a precision of 7 mK between 50 K and 382 K. The ultimate vacuum level of the detector chamber is below 10 −6 mbar. A robust security system avoids both reaching temperatures outside the operational range of the detector and its electronics, and contamination due to vacuum loss. The facility was already used to characterize the VIS-NIR detectors of the Moons And Jupiter Imaging Spectrometer (MAJIS), one of the instruments on board the Jupiter ICy Moons Explorer (JUICE). The versatility provided by the VIS-NIR facility allows its use for the characterization of other astronomical detectors.

“…To carry out such tests, custom setups are demanded, many of them spread along Europe [12] and US [13] with the specifications focused mainly on the electro-optical (EO) characterization of novel detectors or devoted to perform the detector's characterization and validation prior its use on further instrumentation development.…”

The mercury-cadmium-tellurium (MCT) sensors are considered the ideal infrared detectors to equip the focal plane arrays (FPAs) of astronomical scientific missions and nowadays, Europe is not self-sufficient on this technology. To tackle this problem, the Astronomy European Infrared Detector (ASTEROID) project aims to provide Europe with the capability to manufacture high performance infrared focal plane arrays devoted to scientific use, space astronomy and ground-based telescope infrastructures. The resulting detector will be a hybridized MCT array with a CdZnTe substrate of 2k x 2k pixels and 15 µm of pixel pitch. The Institut de Física d'Altes Energies (IFAE) will lead the task to validate the detector performance with respect to the hybridization reliability between the readout integrated circuit (ROIC) and the MCT detector by submitting it to several low temperature thermal cycles. After every thermal stress, the detector will be optically characterized in order to measure any performance degradation and possible problems with the pixel operability. To perform such tasks, two custom setups, focused on optical and cryo-vacuum aspects were developed, which used in conjunction, allow to cool down the detector from the room temperature up to ∼30K while it is electro-optically characterized in terms of linearity, gain, quantum efficiency and cosmetics defects, among others. The whole cryo-vacuum system and the optical setup is fully described in this paper as part of the work packages assigned to IFAE to test the hybridized detector to assess the reliability at operating temperature and after several thermal cycles.
