To determine the operational space for LHCD scenarios we use data from an entire WEST campaign. Using statistical analyses, we define three boundaries corresponding to the three limits listed above. The boundaries are defined for controllable parameters; mainly LHCD injected power and central line integrated density. Moreover, we focus on the LHCD power ramp-up because this is a critical phase where Te0 needs to increase rapidly to cross the tungsten radiation peak. To achieve successfully this phase we find that LHCD power over density and plasma-antenna distance play a major role. The operational space identified and the method used in this study give important guidelines that will help to improve LHCD operation in tungsten environment tokamaks.
