PS/LP Note 2000-01 (MD) CTF3 Tech. Note 2000-09 (MD-LPI) 22 May 2000 LIL bunch length and lattice parameters measurements in March 2000 R. Corsini, A. Ferrari, L. Rinolfi, T. Risselada, P. Royer, F. Tecker CERN, Switzerland Abstract Several studies with the LIL machine have been done during the March 2000 MD session. Bunch length and lattice functions measurements were performed. Preliminary measurements of the bunch length gave a value of 7 ps at low charge, and an uncorrelated energy spread was observed in the data. A normalized rms beam emittance of about 40 π mm.mrad was measured in both the horizontal and vertical directions, and a fair agreement between the experimental data and the predicted values of the lattice functions was obtained.
