A wonderful device added to the Accelerator Table - a multistage (40 coils! ) coilgun MR9. Its peculiarity, in addition to the recuperative scheme, consists precisely in the gigantic number of accelerating steps - a record among all the gauss-guns of the Table. And not only that - to be honest, I have never seen an accelerator with such a number of windings in all the time of my passion for Gauss-building, i.e. for almost 20 years! This design also made it possible to obtain a huge acceleration length of more than 40 cm, which, combined with the relatively low energy spent on the shot (approx. 126 J) gave an absolutely phenomenal efficiency - more than 32 % !! This in itself allows us to call ... Read more »
