Laser-Driven Charged-Particle Acceleration
- Chad Forrest (Laboratory for Laser Energetics (LLE), University of Rochester)
Focused Energy, startup founded in July 2021, is dedicated to commercializing nuclear fusion energy using the proton fast ignition approach. As part of our pathway towards fusion energy, we leverage the technologies developed and employ laser-driven radiation sources as an early spin-off technology to provide further benefits to society. This presentation will elaborate our approach on...
In a recent benchmarking experiment, a tritium beam was generated via the target normal sheath acceleration (TNSA) mechanism using tritiated titanium targets. These targets were irradiated with an on-target intensity of 2x10$^{18}$ W/cm$^2$ with the high-energy (1250-kJ), short-pulse (10-ps) OMEGA EP laser. The energy spectrum of the beam was found to exponentially decrease with a high-energy...
Radioisotopes are indispensable agents in medical diagnosis and treatment, among which copper-62, 64 (Cu-62, 64) and gallium-68 (Ga-68) are medical isotopes widely used in positron emission tomography imaging. Nuclear isomer Mo-93m has a (21/2)$^+$ isomer at 2,425 keV with a half-life of 6.85 h and a (17/2)$^+$ intermediate state that lies 4.85 keV higher at 2,430 keV with a half-life of 3.5...
Shielding for ionizing radiation is a critical safety measure for experiments performed with Joule-class lasers and this is becoming increasingly important for mJ-class lasers, especially at high average power. In-air experimental configurations of laser-generated radiation require further radiation safety considerations as the simpler implementation can lead to an even higher exposure risk....
Laser power has increased into petawatt since the introduce of CPA, leading to many new fields including laser driven ion acceleration. Ions such as protons and deuterons can be accelerated into Multi-MeV by high power laser [1], leading to some applications such as compact neutron source [2,3], proton radiography [4]. For some further applications such as cancer therapy, researchers are...
The application of laser plasma accelerated proton beams [1] in radiation therapy of cancer has been discussed almost since the first demonstration of plasma accelerators reaching 10’s of MeV energies. It was initially motivated by accelerator compactness and cost efficiency, promising a wider spread of advanced therapy methods. Thus, the radiobiology of these intense particle bunches was...
