Sample¶
Eh1 sample¶
The EH1 nuclear-resonant-scattering endstation: the high-resolution monochromator stack that carves the meV / Moessbauer-energy bandwidth, the compound refractive lens focusing, the beam-defining slit, and the sample table.
Enclosure: p01-eh1.
Note
Four high-resolution monochromators (hrm400 / hrm1064 / hrm3d / hrm3w) are the nested / sapphire backscattering analyzers; which is in beam depends on the isotope and resolution (NRS-1). Handles read from p01/motor/eh1.* and the hrm_ener / hrm_ener2 virtual energy axes.
