A B S T R A C T CLIC offers the ability to measure various proprieties of potential new heavy states with high precision. Beambeam effects that inevitably occur at the interaction point affect the precision of physics measurements. The beam parameters can be optimised for a given energy and physics benchmark to minimise their impact. In this paper, the smuon mass extraction and spin determination through a threshold scan are investigated. Two main options realise a centre-of-mass energy scan at
