The nuclear reaction known as proton-boron fusion has been triggered by a subnanosecond laser system focused onto a thick boron nitride target at modest laser intensity …

Can a laser ion accelerator produce a proton beam?

Writing in Nature Physics, Tim Ziegler and colleagues have reached a milestone in the development of such compact laser-driven ion accelerators by demonstrating that proton beams with energies up to 150 MeV can be produced with a petawatt laser 1.

What is proton-boron fusion?

The nuclear reaction known as proton-boron fusion has been triggered by a subnanosecond laser system focused onto a thick boron nitride target at modest laser intensity ($\ensuremath {\sim} {10}^ {16}\phantom {\rule {0.28em} {0ex}} {\mathrm {W}/\mathrm {cm}}^ {2}$), resulting in a record yield of generated \ensuremath {\alpha} particles.

Does a micrometer-size scale-length pre-plasma increase proton acceleration?

Our study demonstrates experimentally that a micrometer-size scale-length pre-plasma can strongly enhance proton acceleration driven by ultraintense laser interaction with not-so-thin foil targets, leading to a threefold increase of the cut-off energy with respect to the case with no pre-plasma.

Are relativistic electron rings a good accelerator/collimator for Ultrahigh energy proton source?

Relativistic electron rings hold the possibility of very high accelerating rates, and hopefully a relatively cheap and compact accelerator/collimator for ultrahigh energy proton source.

What is a high-energy ion accelerator?

Now, proton beams with energies up to 150 MeV have been achieved with a repetitive petawatt laser. High-energy ion accelerators are powerful tools for both fundamental research and applications. A famous example is the Large Hadron Collider, the world’s largest accelerator, built for the study of particle and nuclear physics.
