73. Symmetric Compton Scattering - a possible way to compact monochromatic gamma-ray sources

invited

We report our recent study on the transition between Compton Scattering and Inverse Compton Scattering (ICS), which is characterized by an equal exchange of energy and momentum between the colliding particles (electrons and photons). This regime has been called Symmetric Compton Scattering (SCS) and has the unique property of cancelling the energy-angle correlation of scattered photons, and,...

42. Searching for Dark Matter with Vertically-Aligned Carbon Nanotubes: the ANDROMeDa Project

oral

We present the latest results from the ANDROMeDa (Aligned Nanotube Detector for Research On MeV Darkmatter) project, which was funded with 1MEur PRIN grant by the italian Ministry of Research (MUR). The main objective of ANDROMeDa is the development of the Dark-PMT, a novel light Dark Matter (DM) detector based on vertically-aligned carbon nanotubes. The detection scheme is based on...

oral

In laboratory nitrogen acoustoplasma at pressures from several hundred to several thousand Pa, strong emission lines of molecular nitrogen were obtained at forbidden transitions at 654.81 and 658.36 nm. Strong emission lines were observed both in pure nitrogen acoustoplasma and in a CO2 :N2:He = 1:1:8 laser mixture. In the laser mixture, the emission at the forbidden transition was up to 17...

66. IONIZATION LOSS FOR MEASUREMENTS OF THE DECHANNELING LENGTH OF ELECTRONS

oral

A new method for the experimental study of ionization loss of relativistic negatively charged particles moving in a crystal in the channeling regime using a semiconductor surface-barrier detector with smoothly tunable thickness of the depleted layer is proposed. The ionization loss can only be measured in the depleted layer of the detector. The thickness of the depleted layer in a flat...

57. Anti-shielding of the Coulomb field of relativistic charge in a matter

oral

The Coulomb field of the charged particle in the medium is known to be
shielded, due to the response of the material. In this research, we
show that, unexpectedly, for the relativistic charge moving inside the
medium it is possible that at certain conditions the Coulomb field
will be enhanced rather than weakened! This phenomenon is predicted
theoretically; we also simulated this process...
