Wolfgang Lehmann

Title: **Wolfgang Lehmann: Innovator in Magnetic Technologies**

Introduction

Wolfgang Lehmann, based in Leopoldshafen, Germany, has made significant contributions to the field of magnetic technology through his innovative inventions. With a remarkable portfolio of three patents, Lehmann has been at the forefront of developing sophisticated systems that push the boundaries of magnetic field generation and application.

Latest Patents

Among Lehmann's latest inventions is the **NMR magnet system with superconducting coil in a helium bath**. This system is designed to generate a highly homogeneous magnetic field of high field strength utilizing a superconducting magnet coil situated within a cryostat's first chamber, maintained at supercooled liquid helium temperatures below 4.2K. A unique feature of this design is the connection between the first chamber and a secondary chamber containing liquid helium at approximately 4.2K, both chambers operating at essentially atmospheric pressure. A specialized refrigerator is integrated to cooldown the liquid helium further, achieving temperatures around 1.8-2.3K, thereby enhancing the system's efficiency.

Another notable patent is the **high intensity magnetic field drum separator**. This innovative technology employs an arcuate shaped magnetic system encapsulated within a fixed cryostat that rotates as a drum. It processes a slurry containing magnetizable particles, where particles attach to the drum and are subsequently removed during rotation at a discharge location. The cryostat features an outer wall that mirrors the drum's shape, housing a sector-shaped refrigeration tank that minimizes inward heat transfer, thus optimizing the operating conditions.
