Descrizione
Over the past ten years, laser plasma accelerators (LPA) have shown remarkable progress, influenced in part by advances in laser technology. Their ability to produce quasimonoenergetic electron beams with energies ranging from tens of MeV to tens of GeV in just a few millimeters to centimeters brought LPA to the attention of many scientific and industry fields. Arguably the most important of them is medicine, in a newly developed, so-called FLASH radiotherapy. In this regard, one of the important requirements that an electron beam generated via LPA has to fulfill is shot-to-shot stability in terms of energy, pointing stability, and charge. For this reason, experimental studies have been conducted at the ILIL, INO-CNR, in which electron beam charge has been directly measured by the integrating current transformer (ICT). The results from the measurements have been put into a correlation with the Lanex screen emission signal to obtain a calibration curve.
