Abstract for JLAB Technical Note 01-001  

Knowledge of the true event-by-event beam position on the target is a major issue for the analysis of E93050, the goal being to reach a 0.5mm accuracy. In this document we will discuss what kind of hardware is available for the beam position determination, the different methods we have to calculate this beam position, the rephasing procedure between the beam position monitor and the raster measurements, the part of Espace that computes the bam position, and the effect of these corrections on variables of interest.
