The SEPEM server provides access to a variety of spacecraft data and to
processing and modelling tools. This page provides an overview of the
functionalities implemented on the server.
All channels of the various instrument datasets can be plotted on the
Browsing & plotting page. A limited
download capability is provided as well.
Data Table Manager
The server provides a number of functionalities to process data tables.
A number of these operations involve changing the content of data
tables, which is only allowed for tables that have been created by
the current user. A table copy function
is available to create a user owned version of any data table in the
A number of processing tools are available to prepare the data for usage
with the effects tools and statistical models:
Event List Manager
SEP event lists can be generated on the fly
using any data channel available on the system, or using a
radiation effect response function.
Particle fluence and peak flux spectra can be
generated for any event
list on data tables that provide more than two energy channels for a
given particle type. For proton spectra, analytical spectrum fits can
be superimposed on the plots.
A number of
Geant4 radiation effects tools
have been implemented on the server to evaluate Total Ionising Dose (TID)
and Single Event Upset (SEU) rates:
The SEPEM server implements a number of tools to generate
Use statistical models
Models at 1 AU page, the statistical models can be visualized and interpolated for selected confidence levels. In addition, H flux/fluence probability curves can be converted to ion values using ion abundance ratios.
Away from 1 AU modelling
SEPEM contains a statistical SEP model that makes use of the results of
a shock-and-particle propagation physics based model to estimate event peak
intensities and fluences from 0.2 to 1.6 AU.

event spectra that are used for the helioradial distance scaling
- fluence and peak flux:
perform a statistical analysis using a mission time profile.
The My SEPEM page provides quick access to all
results generated and stored by the current user.
