Upgrade of the two-screen measurement setup in the AWAKE experiment
The AWAKE project at CERN uses a self-modulated 400 GeV/c proton bunch to drive GV/m wakefields in a 10 m long plasma with an electron density of $n_{pe} = 7 \times 10^{14}$ electrons/cm$^3$. We present the upgrade of a proton beam diagnostic to indirectly prove that the bunch self-modulated by imag...

| Sumario: | The AWAKE project at CERN uses a self-modulated 400 GeV/c proton bunch to drive GV/m wakefields in a 10 m long plasma with an electron density of $n_{pe} = 7 \times 10^{14}$ electrons/cm$^3$. We present the upgrade of a proton beam diagnostic to indirectly prove that the bunch self-modulated by imaging defocused protons with two screens downstream the end of the plasma. The two-screen diagnostic has been installed, commissioned and tested in autumn 2016 and limitations were identified. We plan to install an upgraded diagnostics to overcome these limitations. |
