They offer many advantages such as compactness, a comfortable working distance, robustness, and are suitable for use in a wide range of energy. In the scope of the new nuclear resonance ID14 beamline at ESRF, a new transfocator was developed. This transfocator benefits from the previous experience of ESRF’s transfocators to withstand the high power densities (645W/mm2) and total power (405W) generated by the future CPMU18 and the high positioning tolerance required = <± 20µm within the same LCR assembly and between different assemblies. A thermal load analysis was carried out to optimize the cooling design for both 1D and 2D Beryllium lenses unit assembly. The tight alignment specifications was achieved thanks a good machining of both lenses unit mechanical assembly and reference V shaped rail. High positioning repeatability of CRLs actuator is assured by an optimized flexor and a good alignment procedure. The transfocator vessel is installed on a granite and a 4-DOF alignment table.
