Abstract :
The knowledge of the Beam Parameters at the entrance of the SLC final focus is important for modeling the final focus optics and predicting spot sizes and angular divergences at the interaction point. It is also an important diagnostic for measuring possible anomalous emittance growth in the SLC Arcs. Reported is a technique for measuring all the independent beam parameters at the beginning of the final focus. Use is made of the spot size measurements at wire scanners as a function of quadrupole strengths. Results for the SLC 1993 run are presented
