| 1 | Characterisation of Photocathodes Based on Pb Thin Film Deposited by UV Pulsed Laser Ablation显示文摘This work deals with the deposition of lead(Pb) thin films by the U V pulsed laser ablation technique,for their further use as photocathode devices in superconducting radio frequency guns.Scanning electron microscopy and atomic force microscopy analyses were performed to study the morphological features of Pb thin films deposited on Si(100) and Nb substrates.The films showed a granular structure with a nearly fully covered surface only for that one deposited on Nb substrata X-ray diffraction measurements indicate the growth of polycrystalline Pb thin films with a preferential orientation along(111) planes.Results of the photoemission performance of Pb thin film deposited on Nb substrate showed a very encouraging average value of quantum efficiency of 6×10^(-5) through a single-photon absorption process,promoting further studies in the realisation of Pb photocathodes by this | Francisco Gontad Antonella Lorusso Giancarlo Gatti Massimo Ferrario Laura Gioia Passione Luana Persano Nicola Lovergine Alessio Perrone | 2014 | Journal of Materials Science & Technology2014，30，1： | 0 |
| 2 | Simultaneous observation of ultrafast electron and proton beams in TNSA显示文摘The interaction of ultra-intense high-power lasers with solid-state targets has been largely studied for the past 20 years as a future compact proton and ion source.Indeed,the huge potential established on the target surface by the escaping electrons provides accelerating gradients of TV/m.This process,called target normal sheath acceleration,involves a large number of phenomena and is very difficult to study because of the picosecond scale dynamics.At the SPARC LAB Test Facility,the high-power laser FLAME is employed in experiments with solid targets,aiming to study possible correlations between ballistic fast electrons and accelerated protons.In detail,we have installed in the interaction chamber two different diagnostics,each one devoted to characterizing one beam.The first relies on electro-optic sampling,and it has been adopted to completely characterize the ultrafast electron components.On the other hand,a time-of-flight detector,based on chemical-vapour-deposited diamond,has allowed us to retrieve the proton energy spectrum.In this work,we report preliminary studies about simultaneous temporal resolved measurements of both the first forerunner escaping electrons and the accelerated protons for different laser parameters. | Fabrizio Bisesto Mario Galletti Maria Pia Anania Gemma Costa Massimo Ferrario Riccardo Pompili Arie Zigler Fabrizio Consoli Mattia Cipriani Martina Salvadori Claudio Verona | 2020 | High Power Laser Science and Engineering2020，8，2： | 0 |
