The MVD system features a sophisticated design integrating pixel and strip detectors housed in half-barrels and half-disks. The structure includes a sandwich design with carbon and Rohacell layers, supported by rigid carbon fiber layers. The system's cooling pipes are embedded within HTC foam half-disks. The MVD attachment consists of a global frame and a sturdy central support frame connected via three-point fixation. Local support is provided through barrel modules within the MVD half support frame.
