Effects of Laser Polarization and Color on Hybrid Laser Wakefield and Direct Acceleration
Xi Zhang, V. Khudik, A. C. Bernstein +2
We demonstrate that hybrid laser wakefield and direct acceleration (LWDA) can be significantly improved by using two laser pulses with different polarizations or frequencies. The i…
Far-field constant-gradient laser accelerator of electrons in an ion channel
Vladimir Khudik, Xi Zhang, Gennady Shvets
We predict that electrons in an ion channel can gain ultra-relativistic energies by simultaneously interacting with a laser pulse and, counter-intuitively, with a decelerating elec…
Universal scalings for laser acceleration of electrons in ion channels
Vladimir Khudik, Alexey Arefiev, Xi Zhang +1
Direct laser acceleration of electrons in ion channels is investigated in a general case when the laser phase velocity is greater than (or equal to) the speed of light. Using the s…
Synergistic Laser Wakefield/Direct Laser Acceleration in the Plasma Bubble Regime
Xi Zhang, Vladimir N. Khudik, Gennady Shvets
The concept of a hybrid laser wakefield/direct laser plasma accelerator is proposed. Relativistic electrons undergoing resonant betatron oscillations inside the plasma bubble creat…
Compact tunable Compton x-ray source from laser-plasma accelerator and plasma mirror
Hai-En Tsai, Xiaoming Wang, Joseph Shaw +8
We present an in-depth experimental-computational study of the parameters necessary to optimize a tunable, quasi-monoenergetic, efficient, low-background Compton backscattering (CB…
