Subject: toroid size
Hi John, all,
Thanks for the reply regarding toroid size, this confirms my own
experiments and ideas. I believe that this is an area in which a lot
more work can be done, as a published table of results would prove
useful to all. I am aware that Richard Hull, TCBOR has done a large
amount of work on the use of isotropic capacity.
On a different subject, instead of using thoriated tungsten electrodes
in rotary gap designs I use zirconiated tungsten, these are also
available from welding shops and have not dissimilar properties to
thoriated types, but unlike materials containing thorium do not have the
associated alpha particle emissions.
may all your sparks be big ones...
