text: The objective of EFD is to measure the variation of the ionosphere electric field due to perturbations from solar, seismic and anthropic phenomena. It consists of about four meter long independent identical sensors installed at the tips of four booms (~ 4 m long) and it has been designed in collaboration between the LIP (Lanzhou Institute of Physics)of CAST and the INFN division of Roma Tor Vergata. Two different engineering models have been designed and tested in the Faraday Cage at the INFN division of Roma Tor Vergata, and in the Plasma Chamber at the IAPS-INAF Institute in Roma Tor Vergata.

The EFD Flight Model, assembled by the LIP (Lazhou Institute of Physics), has been optimized taking into account the performance of the two instruments.
