Naming Conventions

The purpose of this convention is to define a convention for naming coils, numbering periods, etc.  Conventions follow logically from the right-handed coordinate system being used on NCSX.

Periods

The v=0 plane in the first period is coincident with the X-Z plane.  Other periods are named in order of their f location.

Modular coils

Modular coils are named in order of their f location. The modular coil closest to the v=0 plane in the first period is designated M1.  The next closest is named M2 and so on.  If there are 18 modular coils, the last coil, i.e. the one adjacent to M1 is M18.

TF coils

TF coils are also named in order of their f location. The TF coil closest to the v=0 plane in the first period is designated TF1.  The next closest is named TF2 and so on.  If there are 18 TF coils, the last coil, i.e. the one adjacent to TF1 is TF18.

PF coils

PF coils are named in ascending order of the radial location of their current centroids.  If two coils have the same radial location, the one closer to the horizontal midplane will be named first.  Up-down symmetric coil pairs will be designated as upper (U) and lower (L).  Thus, PF1U is the smallest radius coil.  It is located above the horizontal midplane.  An identical coil, PF1L, is located the same distance below the horizontal midplane.

Bays

Bays are defined as regions of access not blocked by TF coils.  Bay 1 is located between TF1 and TF2.  Bay 2 is located between TF2 and TF3 and so on.

Coil (filament) files

Descriptions of coils as an array of filaments are posted for use in analysis codes.  A discussion of the naming convention for coil files is provided here.
