Description
The main technical difficulties associated with measurement of the top quark
threshold are from uncertainties in the luminosity spectrum due to the large
beamstrahlung and the determination of absolute beam energy of the two
beams. We present the ongoing developments to measure both the beam
energy using electron beam diagnostics and the luminosity spectrum using
the acollinearity of Bhabha events. Also presented are studies of systematic
effects which were believed to cause difficulties with extracting the luminosity
spectrum from Bhabha events.
