An ecloud measurement setup was installed in a straight section of the Main Injector in 2009. The goal of the setup was to compare
the characteristics of different beam pipe coatings when subjected to proton beam. The setup consists of one coated and one
uncoated beam pipe with the same physical dimensions installed at the same location. Four RFAs (retarding field analysers) and
two BPMs (used for RF measurements) have been used to measure the ecloud densities. The RFAs have performed very well and
have collected both the time evolution and energy distribution of the ecloud for bare and two types of beam pipe coating.
