The concept considers two magnetrons in which the output power differs by 15-20 dB and the lower power magnetron being frequency-locked from an external source locks the higher power magnetron. The injection-locked two-stage CW magnetron can be used as an RF power source for Fermilab's Project-X to feed separately each of the 1.3 GHz SC of the 8 GeV pulsed linac. We expect output/locking power ratio of about 30-40 dB assuming operation i","authors_text":"Brian Chase, Daniel Wolff (Fermilab), Frank Marhauser, Gene Flanagan, Grigory Kazakevich, Inc.)
