| Resumo | It is by now well known that electron beams play an important role in generating radio emissions such as commonly observed by spacecraft in the upstream of the Earth's bow shock and those known as type II and III solar radio bursts. Electron beams streaming back from Earth's bow shock into the solar wind have been proposed as a possible source for the electron plasma waves observed by spacecraft in the electron foreshock. Recent researches suggest that multiple electron beams could be injected over a period of time, they tend to lose their individual identity to form just a single beam. In this work we use an electromagnetic PIC code (KEMPO 1D, modi¯ed) to simulate two beams which are injected into a plasma at di®erent times. The ¯rst beam disturbs the background plasma and generates Langmuir waves by electron beam-plasma interaction. Subsequently, another beam is inserted in the system and interacts with the ¯rst one and with the Langmuir waves to produce electromagnetic radiation. The initial conditions for the background plasma and the electron beams are based on the solar wind and electron foreshock observations. In our model we consider that the ¯rst and the second beams (for simple and multiples injections) are, at t = 0, fully injected into the system, i.e., the beam occupies all the system; this is necessary to avoid grid e®ects at the boundaries and gives the possibility of using a more simple model. The preliminary results of our simulation show that the ¯rst beam can produce electrostatic harmonics of plasma frequency while the second beam intensi¯es the emission at the harmonics that are produced for the ¯rst one. The second beam interacts very fast with the Langmuir waves due to the strong electric ¯eld and the phase coupling with the ¯rst beam. An increasing of electromagnetic and kinetic energies is also observed. |
