Independent multi-slit nozzle gas-puff system

A multi-slit nozzle valve, hereafter referred to as the "Synthesizer," with five independent plena was designed, manufactured, and characterized to be used as a gas target for laser-plasma interaction experiments. The reported approach allows one to control the density profile over a wide range of density modulations. To illustrate the flexibility of the multi-slit valve, we present the cases of two different lengths slit nozzles. The 3D gas flow simulations predict a density distribution similar to the measured results, giving the option for future computerized designs of gas load, according to the user's desire. Interestingly, one specific gas load configuration indicates a potential for laser guiding of relevance for laser wakefield acceleration.
