Abstract
Let \(\widehat{G}\) be a spin group over a locally compact non-archimedean local field F of odd residual characteristic. When F has characteristic zero we define \(\beta \)-extensions of the semisimple characters for \(\widehat{G}\). Then we contruct cuspidal types for many new supercuspidal representations of \(\widehat{G}\).
