Evidence of new finite beam plasma instability for magnetic field generation
Amita Das, Atul Kumar, Chandrasekhar Shukla +8
We demonstrate by computer simulations, laser plasma experiments, and analytic theory that a hitherto unknown instability is excited in the beam plasma system with finite transvers…
Magnetic field generation in finite beam plasma system
Amita Das, Atul Kumar, Chandrasekhar Shukla +7
For finite systems boundaries can introduce remarkable novel features. A well known example is the Casimir effect [1, 2] that is observed in quantum electrodynamic systems. In clas…
Soft X-ray harmonic comb from relativistic electron spikes
A. S. Pirozhkov, M. Kando, T. Zh. Esirkepov +37
We demonstrate a new high-order harmonic generation mechanism reaching the `water window' spectral region in experiments with multi-terawatt femtosecond lasers irradiating gas jets…
Identification of high energy ions using backscattered particles in laser-driven ion acceleration with cluster-gas targets
Y. Fukuda, H. Sakaki, M. Kanasaki +16
A new diagnosis method for high energy ions utilizing a single CR-39 detector mounted on plastic plates is demonstrated to identify the presence of the high energy component beyond…
X-ray harmonic comb from relativistic electron spikes
Alexander S. Pirozhkov, Masaki Kando, Timur Zh. Esirkepov +24
X-ray devices are far superior to optical ones for providing nanometre spatial and attosecond temporal resolutions. Such resolution is indispensable in biology, medicine, physics,…
Novel path towards compact laser ion accelerators for hadron therapy: Tenfold energy increase in laser-driven multi-MeV ion generation using a gas target mixed with submicron clusters
Y. Fukuda, A. Ya. Faenov, M. Tampo +20
We demonstrate generation of 10-20 MeV/u ions with a compact 4 TW laser using a gas target mixed with submicron clusters, corresponding to tenfold increase in the ion energies comp…
