Plasma confinement represents a crucial point for plasma-based accelerators and plasma lenses because it can strongly affect the beam properties. For this reason, an accurate measurement of the plasma parameters, as plasma temperature, pressure and electron density, must be performed. In this paper, we introduce a novel method to detect the plasma temperature and the pressure for gas-filled capillaries in use at the SPARC-LAB test facility.

This work is concerned with both theoretical studies and the experimental developments of a plasma device to be used in plasma-based accelerators. In the field of the particle accelerators is growing the interest in the development of compact accelerator machines that also have to be able to exceed the current limits of the conventional accelerator structures. This research activity is leading towards plasma-based devices able to produce accelerating gradients in the GV/m scale.
