High-resolution analysis of the band of radiocarbon methane
Santeri Larnimaa, Lauri Halonen, Juho Karhu +6
We present the first high-resolution measurements and rotational analysis of the fundamental asymmetric stretching vibrational band of radiocarbon methane. A spectrome…
Broadband photoacoustic spectroscopy of with a high-power mid-infrared optical frequency comb
Juho Karhu, Teemu Tomberg, Francisco Senna Vieira +7
We report a photoacoustic spectroscopy setup with a high-power mid-infrared frequency comb as the light source. The setup is used in broadband spectroscopy of radiocarbon methane.…
Radiocarbon Dioxide detection based on Cavity Ring-Down Spectroscopy and a Quantum Cascade Laser
Guillaume Genoud, Markku Vainio, Hilary Phillips +2
Monitoring of radiocarbon (C) in carbon dioxide is demonstrated using mid-infrared spectroscopy and a quantum cascade laser. The measurement is based on cavity ring-down spe…
Laser Wakefield Acceleration Using Wire Produced Double Density Ramps
M. Burza, A. Gonoskov, K. Svensson +7
A novel approach to implement and control electron injection into the accelerating phase of a laser wakefield accelerator (LWFA) is presented. It utilizes a wire, which is introduc…
The self-injection threshold in self-guided laser wakefield accelerators
Stuart P. D. Mangles, Guillaume Genoud, Michael S. Bloom +6
A laser pulse traveling through a plasma can excite large amplitude plasma waves that can be used to accelerate relativistic electron beams in a very short distance---a technique c…
Hollow microspheres as targets for staged laser-driven proton acceleration
M. Burza, A. Gonoskov, G. Genoud +6
A coated hollow core microsphere is introduced as a novel target in ultra-intense laser-matter interaction experiments. In particular, it facilitates staged laser-driven proton acc…
