The traditional electrical field sensing can be realized by utilizing electro-optic materials or liquid crystals, and has limitations of easy breakdown, free assembly and difficult measurement of low-frequency. Here, we propose a new method to realize safe measurement of spatial dynamic electric field by using a micro fiber interferometer integrated with gold nanofilm. The energy of the electri...

For the upgrade of the SIS-18 synchrotron it is of importance that the initial momentum spread of the injected coasting beam does not exceed the limit set by the rf bucket area. The lower limit is determined by microwave instabilities which cause a sudden increase of the momentum spread below a threshold momentum spread. For a coasting Ar beam in the SIS-18 the measured momentum spread as a fun...

The irradiation of foil targets with ultra-intense short laser pulses leads to the generation of an MeV ion beam from the non-irradiated target rear side [1]. The accelerating mechanism was identified to be the build up of a dense sheath of energetic electrons at the non-irradiated, rear surface of the target with an electric field strength exceeding 10 V/m. The acceleration was found to take p...
