	The monochromatic slit is a commonly used device in HEPS beamlines. It can limit the synchrotron beam-spot within a desired size required by the downstream optical equipment. In addition, the four-blade structure is the most widely used form of slit. The slit with this form usually consists of a pair or two parallel tungsten carbide blades. With their edges close to each other, a slit can be formed, and the size of which can be controlled by micromechanical guides. This structure is very suitable for the case of large beamsize. In this work, we have designed a monochromatic slit based on the four-blade form for BF-beamline in HEPS. It can be used in ultra-high vacuum, high luminous flux working environment. The maximum opening range is up to 30mm10mm (HV), while it can allow a white beam of 136mm24mm (HV) to pass through. Furthermore, we adopted a point to surface contact design, which can effectively avoid the over-constraint problem between two guide rails.

WEPPP004	High Heat Load Transfocator for the New ID14 ESRF Beamline	alignment, SRF, undulator, focusing	158
	L. Eybert, P. Brumund, J. Reyes-Herrera ESRF, Grenoble, France
	X ray refractive lenses (CRL) are powerful in-line optics for focusing x-rays. 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.

The monochromatic slit is a commonly used device in HEPS beamlines. It can limit the synchrotron beam-spot within a desired size required by the downstream optical equipment. In addition, the four-blade structure is the most widely used form of slit. The slit with this form usually consists of a pair or two parallel tungsten carbide blades. With their edges close to each other, a slit can be formed, and the size of which can be controlled by micromechanical guides. This structure is very suitable for the case of large beamsize. In this work, we have designed a monochromatic slit based on the four-blade form for BF-beamline in HEPS. It can be used in ultra-high vacuum, high luminous flux working environment. The maximum opening range is up to 30mm*10mm (H*V), while it can allow a white beam of 136mm*24mm (H*V) to pass through. Furthermore, we adopted a point to surface contact design, which can effectively avoid the over-constraint problem between two guide rails.
