C: Notes

1). ESTB - The way secondary particles are produced at ESTB has the inherent risk that the full power beam might be delivered to your experiment. This can happen when the energies between LCLS and the A-line are matched and/or the production target is removed. So suddenly, instead of a single or a few particles it becomes possible that up to around 10^9 particles per bunch might be delivered. Please evaluate the consequences for your experimental apparatus and document them in the proposal.
