DESCRIPTION:Speakers: Marlie van Zyl (University of KwaZulu Natal)\nChorus
  emissions are whistler mode waves propagating through the Earth’s magne
 tosphere in two distinct frequency bands\, typically in the range of 0.1-0
 .8 fce\, where fce is the equatorial electron gyro-frequency. Chorus consi
 sts of discrete elements\, which are normally rising tones\, each of which
  lasts for a few tenths of a second. Chorus is predominantly observed duri
 ng the onset of the substorm expansion phase when energetic electrons are 
 injected into the magnetosphere. As these electrons drift eastward around 
 towards noon\, their distribution becomes unstable to the amplifiation of 
 whistler mode waves. It is thought that the amplification process proceeds
  via the Doppler-shifted cyclotron resonance interaction. Particle-in-cell
  (PIC) simulations\, which simulate the motion of groups of similar partic
 les on a two dimensional grid subject to the self-consistent electric and 
 magnetic fields generated by their spatial distribution and motion\, are u
 sed to simulate the amplification of whistler-mode waves propagating along
  the magnetic field. A population of electrons having a velocity distribut
 ion with a thermal anisotropy is injected into the plasma and the growth o
 f the resulting waves is investigated.\n\nhttps://events.saip.org.za/event
