1. Project title: Femtoseconds PW laser applications on advanced particle acceleration / FLAP

2. Project duration: 26 months (2017-2019)

3. Partners IFIN-HH and INFLPR

4. Objectives:

ELI-NP will start to operate at partial and full capacity in the next two years. However in this commissioning phase, the access to the experimental areas will be limited. Access to the CETAL facility trough this project will enhance and support the implementation of the ELI-NP experiments and diagnostics and sustain our collaboration.

The project objectives are:

O1. Preparation of the experiments, facility operation and procedures.

O2. Benchmark electron and proton acceleration on simple, controllable target and flat laser profile on target together with the installation and test of a full array of diagnostics.

O3. Benchmark simulated results with real data obtained at the CETAL facility. ELI-NP pushes the limits of current knowledge in particle acceleration, which means that it needs to rely on extrapolations of existing models for making simulations and predictions. Thus, testing at CETAL the accuracy of the existing models is of paramount importance.

O4. Explore experimental opportunities available during experiments to test and construct diagnostics. Here we will focus on two experiments: proton radiography and generation of high charge, nC electron beam.

O4. Implement advanced acceleration techniques.
