Based on the yesterday's publication, I have proposed a new parameter for evaluating multistage electromagnetic accelerators - so-called G-factor - and a special separate table has been set up, where all the coilguns will be entered, for which there is a sufficient set of information to calculate the value of G. I ask all Gauss-builders (or just owners of relevant information) to contact me by e-mail eugmit@yandex.ru or through the feedback of the site and report the parameters of accelerators to replenish the data bank.
