Frontend Board Connection We use screws to fix the board to the Faraday cage. T.Schneider/LHCb Muon
In order to assure good long term contact of the aluminum parts we will alodine them. ‘Alodining is the chemical application of a protective chromate conversion coating on aluminum’ This procedure is used by the ATLAS MDT system …. Frontend Board Connection T.Schneider/LHCb Muon
