For over 40 years, The Ogallala Electronics Division of Arnold has manufactured electromagnets (shaped field magnets) made of thin-gauge copper or aluminum foils as well as the more economical wire wound type. The shaped field magnet, sometimes referred to as a solenoid, approaches the ideal for flexibility in generating magnetic fields so desirable for klystron, TWT, ion implantation, chemical etching, chemical dispersion, MRI and other wave guide applications.
Ogallala Electronics manufactures a wide variety of custom design electromagnets which generate uniform or proportioned magnetic field shapes and with a wide range of magnetic field intensities. These electromagnets are either made up of tape wound foil wafers or built up from coils of wire. In the tape wound electromagnets, each wafer is electrically controlled to the precise field strength desired. The resultant field distribution may be uniform or it may have peaks, plateaus and valleys along the axial length of the electromagnet as dictated by the customer requirement. When a specific field shape is desired, the shaped field electromagnet can be designed to that configuration with great precision. Wafers may be of various widths within the electromagnet and they can be made interchangeable. Nominal I.D. and O.D. may be selected to meet application size requirements.
Special designs are available which utilize chilled oil or liquid nitrogen to allow higher than normal current, generating up to 200% greater field intensity than an uncooled design.
