Explosions of xenon clusters in ultraintense femtosecond x-ray pulses from the LCLS free electron laser.

چکیده
Explosions of large Xe clusters ( ~ 11,000) irradiated by femtosecond pulses of 850 eV x-ray photons focused to an intensity of up to 10(17) W/cm(2) from the Linac Coherent Light Source were investigated experimentally. Measurements of ion charge-state distributions and energy spectra exhibit strong evidence for the formation of a Xe nanoplasma in the intense x-ray pulse. This x-ray produced Xe nanoplasma is accompanied by a three-body recombination and hydrodynamic expansion. These experimental results appear to be consistent with a model in which a spherically exploding nanoplasma is formed inside the Xe cluster and where the plasma temperature is determined by photoionization heating.

The plasma dynamics of single mesoscopic Xe particles irradiated with intense femtosecond x-ray pulses exceeding 10(16) W/cm2 from the Linac Coherent Light Source free-electron laser are investigated. Simultaneous recording of diffraction patterns and ion spectra allows eliminating the influence of the laser focal volume intensity and particle size distribution. The data show that for clusters...
متن کاملX-ray Pulse Duration Control in the LCLS
X-ray pulse duration control is critical to exploring the ultra-fast science at an x-ray freeelectron laser (FEL) facility such as the Linac Coherent Light Source (LCLS). The pulse length of a typical electron bunch that drives a self-amplified spontaneous emission (SASE) FEL is limited to the order of 100~200 fs, due to short-bunch collective interactions. Many novel schemes have been proposed...

The formation of relativistic electron mirror produced via ioniza-tion of thin solid target by ultraintense femtosecond laser pulse is considered with the help of computer simulations. It is shown that the reflection of weak counter-propagating wave from such a mirror can produce the coherent radiation in x-ray and gamma-ray bands. The spectrum of up-conversed radiation is investigated.
متن کاملUltra-short Electron Bunch and X-ray Temporal Diagnostics with an X-band Transverse Deflector
The measurement of ultra-short electron bunches on the femtosecond time scale constitutes a very challenging problem. In X-ray free-electron laser facilities such as the Linac Coherent Light Source (LCLS), generation of subten femtosecond X-ray pulses is possible, and some efforts have been put into both ultra-short electron and X-ray beam diagnostics. Here we propose a single-shot method using...
متن کاملHidden charge states in soft-x-ray laser-produced nanoplasmas revealed by fluorescence spectroscopy.
Highly charged ions are formed in the center of composite clusters by strong free-electron laser pulses and they emit fluorescence on a femtosecond time scale before competing recombination leads to neutralization of the nanoplasma core. In contrast to mass spectrometry that detects remnants of the interaction, fluorescence in the extreme ultraviolet spectral range provides fingerprints of tran...
