Aiming for the improvement of the reliability and maintainability of the LHC linear wire scanners, a completely new concept is currently under development. The innovative design will eliminate the use of bellows, feature a more precise and optimized wire positioning system, and incorporate a significantly more robust and resilient mechanical structure. Four next-generation instruments are scheduled for installation in the LHC during Long Shutdown 3, enabling both horizontal and vertical beam profiling for beam 1 and beam 2 with improved accuracy and stability. This paper presents the conceptual study, detailed mechanical design, integration strategy, and the initial experimental tests of the newly developed magnetically driven linear wire scanner.
