Description
The IFMIF-DONES facility located at Escúzar in Spain will consist of an accelerator delivering 125 mA of 40 MeV deuterons onto a liquid lithium target. The beam profile at the target will have a rectangular footprint with two side peaks to satisfy the irradiation requirements. The environment conditions are characterized by a high radiation background and the presence of lithium vapor. Additionally, deuteron scattering with residual gas and secondary-electron production occur. To measure the footprint under these conditions optical methods are designed based either on measuring Optical Transition Radiation (OTR) of the beam passing through the liquid lithium or on the Beam Induced Fluorescence (BIF) of the residual gas in the proximity of the liquid lithium. Both alternatives have its advantages and drawbacks. In this paper it is described the pros and cons of both alternatives. Furthermore, an experiment to better characterise the OTR response in liquid lithium is also presented.
