Electro-Optical Sampling (EOS) based temporal diagnostics allows to precisely measure the temporal profile of electron bunches with resolution of few tens of fs in a non-destructive and single-shot way. At SPARC_LAB we adopted the EOS in very different experimental fields. We measured for the first time the longitudinal profile of a train of multiple bunches at THz repetition rate, as the ones required for resonant Plasma Wakefield Acceleration (PWFA). By means of the EOS we demostrated a new hybrid compression scheme that is able to provide ultra-short bunches (< 90 fs) with ultra-low (< 20 fs) timing-jitter relative to the EOS laser system. Recently we also developed an EOS system in order to provide temporal and energy measurements in a very noisy and harsh environment: the electrons ejected by the interaction of a high-intensity (hundreds TW class) ultra-short(35 fs) laser pulses with solid targets by means of the so-called Target Normal Sheath Acceleration (TNSA) method.

Abstract
Electro-Optical Sampling (EOS) based temporal diagnostics allows to precisely measure the temporal profile of electron bunches with resolution of few tens of fs in a non-destructive and single-shot way. At SPARC_LAB we adopted the EOS in very different experimental fields. We measured for the first time the longitudinal profile of a train of multiple bunches at THz repetition rate, as the ones required for resonant Plasma Wakefield Acceleration (PWFA). By means of the EOS we demostrated a new hybrid compression scheme that is able to provide ultra-short bunches (< 90 fs) with ultra-low (< 20 fs) timing-jitter relative to the EOS laser system. Recently we also developed an EOS system in order to provide temporal and energy measurements in a very noisy and harsh environment: the electrons ejected by the interaction of a high-intensity (hundreds TW class) ultra-short(35 fs) laser pulses with solid targets by means of the so-called Target Normal Sheath Acceleration (TNSA) method.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
