TYPE 2J50\ PFN \ 6 Stage \
Continue Analysis and Upgrade

Experimental Setup:

This is a continuation of the PFN3A construction and continued B2Spice and data analysis regarding its application to the only WWII 2J50  magnetron I bought fron ebay that works . The photos directly below shows the experimental setup for the magnetron holder and electromagnet ;otherwise the remaining experimental set up is identical to the 2J55 description.
