EuCARD is a common venture of 37 European Accelerator Laboratories, Institutes, Universities and Industrial Partners involved in accelerator sciences and technologies. The project is an Integrating Activity co-funded by the European Commission under Framework Programme 7 for a duration of four years, starting April 1st, 2009.

The project was finished in summer 2013.

SRF Tasks:

Task 10.7 - Superconducting RF Gun at ELBE

• Sub-task 1: For the slice diagnostics system, beam dynamic simulations will be carried out. Commissioning of the diagnostics at ELBE, measurement of slice emittance and energy spread of the SRF-Gun beam, in particular for high bunch charges around 1 nC will be performed by HZB and FZD.
• Sub-task 2: Improvement of the GaAs photo-cathodes preparation chamber which is now used for Cs2Te photo-cathodes. Lenses and mirrors in the laser beam line will be replaced since green laser light will be used for the operation of the gun. For this work FZD is responsible for this work.

• Sub-task 3: The measurements in this sub-task concerns the i) properties of photo-cathodes like quantum efficiency, live time, thermal emittance, ii) the long term behaviour of the RF cavity, i.e. unloaded quality factor, maximum gradient, field emission, iii) later measurements with GaAs photo-cathodes.
