Low emittance lattice for LEP

In order to obtain the largest luminosity with LEP2, it is attractive to make the beam emittance as small as possible because the beam-beam effect is not a limitation at the energy of E~90 GeV for the obtained bunch currents. This can be achieved with a high tune lattice. Two possible candidates are...

description In order to obtain the largest luminosity with LEP2, it is attractive to make the beam emittance as small as possible because the beam-beam effect is not a limitation at the energy of E~90 GeV for the obtained bunch currents. This can be achieved with a high tune lattice. Two possible candidates are lattices with a horizontal phase advance of 108o or 135o per cell. Both have a vertical phase advance of 60o. These lattice were developed during 1994 and the results are presented. tests to reach high intensity for the 108o lattice were performed and the bunch current achieved is compared with expectations. For this lattice the detuning v.s. intensity and several optics parameters were measured as well.
