Abstract : The dependence of electron beam lifetime on vertical aperture is measured for the storage ring BESSY providing quantitative information necessary for estimating the usable gap sizes of the variable vacuum gap undulator being built. The data allow one to distinguish between different lifetime limiting mechanisms thus yielding useful storage ring diagnostics. General agreement with available particle loss models is observed.
