Well I did say to Terry that we'd try to find an estimator for Lfac which is defined as Les/Ldc, since this may be helpful with E-Tesla6. (Ldc is the one that's measureable, but Les is the one that plugs into the formula for Fres, hence the need for a relation between the two). Another one to look for would be an estimator for Fres and for Cee, both of which would be potentialy useful formulae for coil builders. An estimator for Zft would also be useful for CW coilers. Don't bother doing anything with the Q, Rin, and gain fields as these are based on loss estimates from Medhurst tables, which don't really apply to TCs. I've noticed values of Lee larger than Ldc, eg at small h/d. This will mean a slight revision to pn2511, so that's a bit of progress. Have fun, and I'll look forward to seeing the 'Anderson formula' for Fres take its rightful place in the coiler's toolkit. Cheers, -- Paul Nicholson, Manchester, UK. --
