| Abstract |
Beam characteristics at low energy are an absolute necessity for an acceptable injection in the next stage of a linear accelerator, and are also necessary to reduce beam loss and radiation inside the machine. CEA is taking part of ESS linac construction, by designing Emittance Measurement Units (EMU) for the Low Energy Beam Transport (LEBT). The EMU are designed to qualify the proton beam produced by the INFN Catania ion source. This measurement has been decided to be time resolved, allowing to follow the beam emittance reduction, during the pulse length. A 1Mhz acquisition board controlled by EPICS save raw datas to an archiver in order to be able to post process the measurements for time resolution. The design corresponds to an Allison's scanner, using entrance and exit slits, electrostatic plates and a faraday cup. The beamstopper protects the device and can be removable to fit to beam power. It has been manufactured by the CEA/LITEN with copper tungsten HIP technique. This article report the first measurements on the ESS injector at INFN CATANIA.
