I presume he was testing using a CW source? Unfortunately, that 
approach has limited applicability to cap discharge systems which 
impart fixed energy shots to the secondary and also include a primary 
spark gap which loses a lot of power if the primary inductance is low.

Jay was using a static gap. He used it to build an electron beam gun that
could shoot electrons into the air.
