Solar energetic particle (SEP) events are produced in coronal shocks driven by fast CMEs. The SEP intensity-time profiles observed at 1 AU show a general trend of shorter rise times with magnetically better connected solar source longitudes. Event peak intensities also tend to be higher when preceded by other CMEs from the same source regions, showing that the coronal environment must play an important role in the development of a SEP event. Do the transient coronal environments have any systematic effect on the timescales of SEP events observed at 1 AU? As a first step we examine the times from CME onsets to half-peak intensities and the durations of E = 20 MeV SEP events to see how they depend on CMEs that precede or follow the SEP injections. We compare SEP event groups selected for the shortest and longest associated timescales and from two source longitude ranges. Contrary to the peak SEP intensities, the SEP event timescales appear independent of histories of preceding CMEs.
