Fast growing double tearing modes in a tokamak plasma
Andreas Bierwage, Sadruddin Benkadda, Satoshi Hamaguchi +1
Configurations with nearby multiple resonant surfaces have broad spectra of linearly unstable coupled tearing modes with dominant high poloidal mode numbers m. This was recently sh…
Inhomogeneous Energy - Density Driven Instability in Presence of a Transverse DC Electric Fields in a Magnetized Plasma Cylinder
Suresh C. Sharma, Satoshi Hamaguchi
Temporal evolution of the inhomogeneous energy density driven instability (IEDDI) is examined in presence of a nonuniform transverse dc electric field in collisional magnetized pla…
Current-Driven Dust Ion-Cyclotron Waves in Presence of a Transverse DC Electric Fields in Magnetized Plasma with Charge Fluctuations
Suresh C. Sharma, Satoshi Hamaguchi
The current-driven electrostatic ion-cyclotron (EIC) instability is studied in presence of a transverse dc electric fields in a collisional magnetized dusty plasma. We derive the a…
Gain and Efficiency Enhancement in Free Electron Laser by Means of Modulated Electron Beam
Vivek Beniwal, Suresh C. Sharma, Satoshi Hamaguchi
Beam premodulation on free electron laser (FEL) offers considerable enhancement in gain and efficiency when the phase of the premodulated beam is -pi/2 and the beam is highly modul…
