Abstract：
High frequency electromagnetic fields induced by high-energy e-beam can cause resonance depolarization of the HERMES transversely polarized gas target. This paper presents the research results on the mechanism of depolarization and the position where resonance σ₂₄ takes place. About 3% depolarization has been saved after avoiding such resonance by fixing the magnet field far from resonance position according to the measured results.
