Title: Investigation and analysis of very high energy accelerators for radiation simulation
Very high energy ion accelerators (E/n ~1GeV) available in Europe will be investigated in detail. Programmes for their
characterization for use in space applications will be prepared and executed, and experiments performed to investigate
energy-related phenomena. Facilities currently used by agencies and industry produce ions of relatively low energy, so that
their ranges in typical components are limited. This is very unlike ions in space whose energies are so high that they can
penetrate at least several cm of material. As a result there are many “range effects” where ions stopping in sensitive volumes
deposit more than expected while others not reaching sensitive volumes do not contribute. Resulting effects calculations
based on such data are incorrect and may explain discrepancies between in-orbit experience and pre-flight estimates. In
addition, future manned programmes and increasing investigation of biological effects necessitates access to such machines.
In addition to the detailed experimental investigation of these effects, detailed modelling of the processes will be undertaken,
and comparisons made with results from “low energy” accelerators). The activity includes: 1. Analysis of existing and required
facilities. 2. Experiments on effects in sub-100nm devices and simulation of beam interactions at sensitive node level. 3.
Establishment and demonstration of new methods of analysis. 4. Development proposals.

Title:
Rapid Reverse Monte Carlo and Ion Physics for Dose and SEE
Recent consultations with industry, the harmonisation process, project applications and results of R&D activities indicate the
need for specific physical attributes in radiation effects simulations In particular, a “reverse” (adjoint) Monte Carlo simulation
for rapid, highly accurate total dose calculations is lacking in Europe and has been identified as a key simulation improvement
capable of dramatically reducing mass and design margins. Likewise the analyses of Single Event Effects (SEE) and
Non-Ionising Energy Loss (NIEL) are becoming increasingly critical for a broad range of mission domains and have also been
identified as priorities for simulation improvement. The underlying physics models utilised in present tools need to be updated
and validated for engineering applications.
This activity will focus on detailed radiation interaction physics modelling, including both theoretical and data-driven
approaches, for incident particles, materials, and technologies typically encountered in a broad range of missions. The
development shall include both prompt interactions (hadronic (~ion) and electromagnetic (e--) processing occurring at the
site of the particle interaction) as well as effects at the semiconductor level (e.g. charge collection mechanisms). The
resulting software shall be based on Object-Oriented technologies and implemented in the Geant4 particle transport toolkit,
ensuring their availability to industrial tools. Validation of the models shall be carried out by rigorous comparisons to existing or
specially generated experimental accelerator data, other Monte Carlo codes and/or analytical methods.
Deliverables:
New radiation interaction physics models, aimed specifically at shielding and component engineering applications and
implemented in the Geant4 particle transport toolkit
