1. CONTEXT OF THE PhD

The MNT group is participating in the planning of future missions to Mars and theMoon within the context of an ongoing European Space Agency (ESA) project.

In this context, the MNT group is working in the design and fabrication of mitigation strategies for Lunar Dust, which is one of the worst problems in Moon exploration [RD1-RD3]. The strategies will be focused on the design of Smart Electrostatic Dust Shields. Background: work by the UPC group on trapped charge controls for MEMS switches, [RD4-RD8].

2.OBJECTIVES OF THE THESIS

Development of sensing and actuation strategies for the control of trapped charge in Lunar dust. Design of active controls loops for charge sensing and dust removal.

Testing of the proposed strategies on optical surfaces (planar windows and lenses). Actuation electrodes will be fabricated with Transparent Conductive Oxides (TCO).

Testing of the proposed strategies on seals. Seals are required to isolate samples from external contamination (for example ISRU).

3.FINANCIAL CONDITIONS

We expect the candidates to apply for the competitive FI and/or FPU fellowships.These fellowships, in case they are granted to the candidate, fund the PhD for 4 years. The net quantities for the PhD candidate are in the range: 1000-1100 euros/month.

Prospective students must have a strong background in analog and digital electronics.Physics background will also be very valued. The call for these fellowships is scheduled for July-September 2020.
