Machine parameters

An up-to-date version for the parameters of the machine at the various centre-of-mass energies (Z peak, WW threshold, HZ cross-section maximum, and top-pair threshold) can be obtained from this document, and are summarized in the table below. These "baseline" parameters have been recently approved with a realstic optics, and conservative beta* values. The luminosities expected at each centre-of-mass energies in this new baseline (summed over the two interaction points and compared to other projects on the market) is shown in the figure below (in red). The target values, which might be achievable with 4 IPs and more agressive beta*, are displayed with the purple/pink dashed curve.
