We ha.e inquired into a.mea.s to decrea.e the number of cha.ged pa.ticles esca.ing from a.loss cone of a.ma.netic mirror rea.tor a. ma.y a. possible. We previously reported the wa. of insta.ling a.supplementa. ma.netic mirror (which ha. a.cyclotron hea.ing spa.e within) a. the exit of a.ma.n ma.netic bottle. The cyclotron hea.ing spa.e wa. set to increa.e a.reflection-efficiency of the supplementa. mirror. We could not suppress the loss of the esca.ing deuteron ions sufficiently even with a.very long mirror a.d a.very powerful electric field. Then, in this work we propose a.new pla. of insta.ling a.other supplementa. mirror besides the previous supplementa. mirror. a.new mirror is set perpendicula.ly to the center a.is of the ma.n bottle. By the a.dition of the perpendicula. mirror, a. efficiency of sending ba.k of esca.ing deuteron ions is considera.ly theoretica.ly improved. a.so in the previous work, since we did not touch how to supply a.high-frequency electric field to the cyclotron hea.ing spa.e, here we consider supplying it by a. extra.rdina.y-wa.e with a.cyclotron frequency. It is mentioned tha. propa.a.ion of a. extra.rdina.y-wa.e with a. electron cyclotron frequency depends on a.ma.netic field strength a.d density of esca.ing electrons.
