A high brightness electron Linac is being built in the
Compton Gamma Source at the ELI Nuclear Physics facility
in Romania. To achieve the design luminosity, a train of 32
bunches, 16 ns spaced, with a nominal charge of 250 pC will
collide with the laser beam in the interaction point. Electron
beam spot size is measured with optical transition radiation
(OTR) profile monitors.
Furthermore, OTR angular distribution strongly depends
on beam energy. Since OTR screens are typically placed in

A high brightness electron LINAC is being built in the Compton Gamma Source at the ELI Nuclear Physics facility in Romania. To achieve the design luminosity, a train of 32 bunches, 16 ns spaced, with a nominal charge of 250 pC will collide with the laser beam in the interaction point at two electron beam energies, namely 280 MeV and 720 MeV. Electron beam spot size is measured with optical transition radiation (OTR) profile monitors.
