Funding: Work supported by Fermi Research Alliance, LLC under Contract No. De-AC02-07CH11359 with the United States Department of Energy The Fermiab Booster accelerates beam from 400 MeV to 8 GeV at 15 Hz. In the PIP (Proton Improvement Plan) era, it is required that Booster deliver 4.2·1012 protons per pulse to extraction. One of the obstacles for providing quality beam to the users is the longitudinal quadrupole oscillation that the beam suffers from right after transition. Although this oscillation is well taken care of with quadrupole dampers, it is important to understand the source of these oscillation in light of the PIP II requirements that require 6.5·1012 protons per pulse at extraction. This paper explores the results from computer simulations, machine studies and solutions to prevent the quadrupole oscillation after transition. Author would like to thank S. Chaurize, C. Drennan, W.
