The invention relates to a passing device for optical fiber systems, resistant to pressure differences, which allows the transmission of an optical signal, by means of an optical fiber, between two enclosures inside which the gas or liquid pressure is different, or towards the interior of an enclosure inside which the gas or liquid pressure is different from the outside pressure.
The invention relates to a highly efficient CW COlaser multifunctional synthesis installation meant for producing nanotubes by laser ablation. According to the invention, the installation comprises a reaction chamber (), a gravitational system () for the recovery of nanotubes, a system () for transferring and processing the laser beam, a vacuuming system (), a cooling system (), a multi-adjustable support assembly (), a high power laser source () and also auxiliary systems consisting of a compressed air source and a process gas source and a process control and power supply panel ().
The invention relates to a method of synthesis of pure materials by laser ablation, in direct flux, from multiple non-parallel targets, intended to be used in electronic industry for thin film deposition and for the synthesis of nanometric materials. According to the invention, the method comprises the simultaneous laser ablation of a plurality of non-parallel targets, the confining of the ablation plasmas in a direction which differs from the initial direction and passing the resulting ablation plasma or the precursors thereof through an adjustable aperture(s) trap.
The invention relates to an atmospheric-pressure cold plasma generator system and to a method for modifying the properties of the inner surfaces of small diameter dielectric tubes. The claimed system comprises two electrodes (3 and 6), a small RF cavity electrode (3) placed inside a tube (4) to be treated and a ring-shaped mass electrode (6) mounted outside the tube (4), the two electrodes (3 and 6) being fastened and connected by means of some long and stiff conductors (2 and 7) to an adapter (5) which comprises an RF cable box.
The invention relates to a dosimeter of the optical fibre calorimeter type employed to measure the integrally absorbed dose in irradiation with accelerated particle beams.
