“…This competition was won by an international consortium led by the Institute for Plasmas and Nuclear Fusion (IPFN), a research unit of Instituto Superior Técnico (IST) [13,14]. The European Shock Tube for High-Enthalpy Research (ESTHER) was developed in the scope of this contract and is in its final commissioning phase [15]. Such a higher performance shock tube facility requires state-of-the-art instrumentation.…”

“…A small-scale combustion driver was previously tested in order to de-risk the development of the full-scale driver [14]. Whereas the qualification tests of ESTHER are ongoing [15], the tests of the combustion driver were successfully completed. The driver of ESTHER is a 47-liter cylindrical 200 mm internal diameter combustion chamber, capable of handling He:H 2 :O 2 or N 2 :H 2 :O 2 mixtures with filling pressures up to 100 bar and post-combustion deflagration pressures of 660 bar.…”

The European Shock Tube for High-Enthalpy Research is a new state-of-the-art facility, tailored for the reproduction of spacecraft planetary entries in support of future European exploration missions, developed by an international consortium led by Instituto de Plasmas e Fusão Nuclear and funded by the European Space Agency. Deployed state-of-the-art diagnostics include vacuum-ultraviolet to ultraviolet, visible, and mid-infrared optical spectroscopy setups, and a microwave interferometry setup. This work examines the specifications and requirements for high-speed flow measurements, and discusses the design choices for the main diagnostics. The spectroscopy setup covers a spectral window between 120 and 5000 nm, and the microwave interferometer can measure electron densities up to 1.5 × 1020 electrons/m3. The main design drivers and technological choices derived from the requirements are discussed in detail herein.
