 note = {0000-0002-7698-0223, The effects of the deformation of the flux surfaces into a “D shape” on vacuum heliotron configurations are examined numerically. In this study, one poloidal coil on the mid plane just inside the helical coils is assumed to be installed so that the current in the coil can deform the surface shape. Such deformation gives the advantage that the clearance between the helical coil and the outermost surface can be enlarged, which is crucial for the divertor action in heliotrons. The effects of the deformation on other vacuum properties are also discussed, such as rotational transform, magnetic well, and |B|min contour. We also focus on such effects on downsized configurations.},
