  The Gamma Beam Source (ELI-GBS) is a high brightness electron LINAC that is being built at the ELI Nuclear Physics (ELI-NP) facility in Romania. The ELI-GBS aims to produce high quality gamma beam through Compton Backscattering. A train of 32 bunches at 100Hz with a nominal charge of 250pC is accelerated up to 740 MeV. Two interaction points with an IR Laser beam produces the gamma beam at two different energies. In order to measure the electron beam spot size and the beam properties, the LINAC is equipped with several optical transition radiation (OTR) profile monitors. Those OTR screens must sustain the thermal and mechanical stress due to the energy deposited by the bunches. We present a numerical (ANSYS) study of the thermo-mechanical issues due to beam energy deposition in the screens; our analysis will cover both the steady state and transient regime.
