A strong homogeneous magnetic field is required for a gyrotron as well as other applications. For many applications, the natural solution is a superconducting magnet, but for some applications, this solution is not suitable. In this paper, a copper-based design of a continuous, strong magnetic field source is presented. The design is based on a spaced Bitter solenoid with various radii, and with a transversely flowing cooling system. The results of the design are ±0.19% homogeneity over a length of 25 mm, and a power consumption of 12.2 kW for continuous operation. These results show that such a concept is applicable for a 95-GHz gyrotron operating in a long pulse or even continuous mode.
