Design of vacuum instrumentation

This research line is performed in collaboration with Jesus Sobrado (Centro de Astrobiología-INTA-CSIC) and Gary Ellis (ICTP-CSIC)

We have developed new instruments to address interdisciplinary problems that requires unconventional approaches based on vacuum technology. Particularly we have built vacuum chambers for simulating different astronomical environments, as planets (Mars) or evolved stars atmospheres (Stardust Machine, see astrochemistry research line).

Instrumentation is designed in such a way that in-situ characterization techniques (electron-based or optical) can be adapted.

Also, we have designed a fast-valve able to introduce liquid drops into vacuum systems. This valve, called ALI, is currently commercialized by Bihurcrystals and it is very valuable to deposit large molecules or nanostructures on controlled surfaces.
