Description
We presented gantry design with compact size and high energy acceptance satisfying rotation invariant condition. three identical 90 degree superconducting canted cosine theta (CCT) bending magnets (BMs) was used in a gantry to make gantry size be small, however, one BM have reverse bending angle. For high energy acceptance, low dispersion should be maintained through a gantry, therefore, alternating-grediant quadrupole coils was introduced in each 90 degree BM. Because rotator beam line was not intorduced in this gantry, point-to-parallel imaging in the entire gantry is satisfied to ensure rotation invariant optics. Downstream scanning method is adapted in this gantry in order to ensure small nonlinear beam dynamics in a last BM by making the BM's bore radius be small. 90 degree CCT BM design was not fullfilled yet and it wii be future work.
