S.Burke, M.R.Howells, Z.Hussain, S.Locklin, J.Spring
Beamline
9.3.2
All design choices are driven by:
- The desired resolution
- The nominal photon wavelength
Design Parameters
| Energy/Wavelength Range | Design Goal | 40-120 eV; 30-10 nm |
| Resolution | Design Goal
Demonstrated (preliminary) |
65 µeV (Resolving Power
= 106 at 65 eV)
250 µeV |
Figure 1. Neon Discharge Spectrum. Visible lines are used for coarse alignment of the beamsplitters to each other and to the mirrors. The resolution, which is independant of wavelength, is demonstrated by this spectrum to be within a factor of 4 of the design goal. A further factor of 2 is expected to be gained in the final alignment run.
A detailed list of the technical specifications is given here.
