| definition |
- One of the scientific instruments of SOHO is the energetic particle instrument
ERNE (Energetic and Relativistic Nuclei and Electron) of the University of
Turku. The energy eruptions in the solar atmosphere can lead to the
acceleration of local gas particles to extremely high energies and their
injection into the interplanetary space. These fast moving streams of particles
are recorded by ERNE. At times, when there is no energetic particle production
at the Sun, ERNE is observing the continuous flux of energetic particles from
Milky Way (galactic cosmic rays) , and from the boundary of the heliosphere
accelerated by the termination shock (anomalous cosmic rays). The two particle
experiments of SOHO, COSTEP and ERNE, are carried out in the CEPAC
collaboration.
The ERNE Sensor Unit (ESU) has two energetic particle sensors: LED and HED.
Further, all analog and digital electronics as well as the Data Processing Unit
(ESU-DPU) of these sensors are within this unit.
