Radiation Damage Considerations in Accelerator Beam Environments | |
|
||
| The impact of radiation upon equipment used on accelerator beam lines is a continuing concern. Materials, cabling and instrumentation will experience aging and degradation and even failure depending on the nature of the radiation and the intensity of the fields. This discussion will review the fundamentals of radiation interactions and look at possible mechanisms for damage. In the case of electron accelerators producing photon beams, ionization effects will tend to dominate but if the energies are high enough, secondary charged particles and neutrons are created that can cause atomic displacements and even impurity production. We can also distinguish between cumulative effects and single event effects. For instrumentation, the topic of radiation damage can be divided into electromagnetic and bulk damage components. Hadrons can also produce bulk damage. Strategies to minimise or delay the effects of radiation damage need to take these issues into account. Some examples will be discussed. | ||
