Effects of driver bandwidth upon resonantly heated electrons

Journal Article · · Phys. Rev. Lett.; (United States)
Experimental data are presented which show that increased bandwidth of an electromagnetic driver can reduce the hot electron temperature due to resonant absorption. This work, done at microwave frequencies, shows that T/sub H/a(Dw/w)/sup -0.25/. It was also observed that the hot electron density increases with increasing bandwidth such that the heat flux (Q/sub H/an/sub H/T/sub H//sup ts3/2/) is nearly constant as a function of bandwidth.
