Abstract: The eigenvalue problem of the secular trapped ion temperature gradient mode is solved by employing invariant imbedding method. The numerical methods removing the singularity of the eigen equation at zero point are presented for even mode and odd mode, respectively. The calculation for a concrete physical problem is outlined.

Key words: Secular trapped ion temperature gradient mode, Invariant imbedding, Singularity
