Application of laser plasma in propulsion

Laser Accelerated Plasma Propulsion System (LAPPS)

Recently conducted experiments at the University of Michigan and elsewhere have shown that ultrashort pulse (ultrafast) lasers could accelerate charged particles to relativistic speeds. For example a picosecond laser pulse with only one joule of energy can accelerate an electron to MeV energy in just a few microns distance. This takes place through the high gradient potential that manifests its...

Laser Accelerated Heavy-ion Plasma Propulsion System

The Ultrafast “Laser Accelerated Plasma Propulsion System” LAPPS makes use of lasers with very short pulse lengths to accelerate charged particles to relativistic speeds. Recent experimental data reveal that high intensity lasers are capable of producing collimated, charge-neutral proton beams containing more than 6 x 10 particles at a mean energy of 5 MeV with a total beam energy of 500J. If u...

the role of application of dynamic assessment approach in improvement of iranian efl writing performance at different language proficiency levels

the present study sought to investigate the role of dynamic assessment (da) in improvement of iranian efl writing performance at different language proficiency levels. to this end, after conducting the quick placement test, 60 iranian efl learners were assigned to two groups with different language proficiency levels. in both groups each participant wrote two compositions, one before and one af...
