The compensation of the long-range beam-beam interactions using DC wires is presently under study as an option for enhancing the machine performance in the framework of the High-Luminosity LHC Project (HL-LHC). The original idea dates back more than 15 years ago. After the installation of four wire prototypes in the LHC in 2018, a successful experimental campaign was performed. The experimental setup and the main results are reported in this paper.
