Monochromator

In the project, we are planning to construct about three leading beamlines. We have disccused two types of monochromators for the leading beamlines. These prototype monochromators will be used in other beamlines.

1. Design Concepts

1.　Acheive a high-throughput without entrance slit.
2.　One grating can cover the broad energy range.
3.　A standard performance should be1012photons/sec, in 10000 E/E.
4.　Spot size should be under 50m at a sample position.
