Abstract :
The authors present a novel technique to measure separately the transverse sizes of e/sup +/ and e/sup -/ beams in linear colliders. It is based on analyzing patterns of beamstrahlung energy recorded while the two beams are scanned across each other. After establishing the principle of the method, the predicted radiated energy profiles to actual measurements are compared. The consistency of the results is verified with an independent beam size determination based on coherent mutual electromagnetic deflection of the two beams.<>
