	Funding: "Funded by Novo Nordisk Fonden for the MicroMAX project, grant number NNF17CC0030666" The MicroMAX beamline at MAX IV Laboratory will employ two detectors to be used independently and move along the beam depending on the diffraction target resolution, starting close to the sample hanging partially over the sample table. The X-ray beam can be deflected by Kirkpatrick-Baez (KB) mirrors in the horizontal and vertical directions or pass undeflected. The MAX IV Design office designed a detector stage as an in-house project based on the ALBA table skin concept [1] to switch between the two detectors and accurately position the selected detector, either with or without the KB mirrors. To achieve stability and precision during translations, a large granite block is used, as well as preloaded linear and radial guides, and preloaded ball screws with stepper motors and, in most cases, a gear box. Flexures are used to allow linear motion’s pitch and yaw angles. The various motions are layered so that alignment to the beam axis can be done first, and then sample-to-detector distance can be adjusted independently. A Finite Element Analysis (FEA) were performed to achieve a stable design and measurements of resonance frequencies on the finalized stage were done to verify it. * Colldelram C., Rudget C., Nikitina L.

WEPPP054	Vibration Analysis of Storage Ring Girder for the Korea 4GSR	storage-ring, operation, synchrotron, alignment	236
	G.W. Hong, T. Ha, H.S. Han, H.-G. Lee PAL, Pohang, Republic of Korea
	Ensuring the mechanical stability of the girder for a 4th generation storage ring (4GSR) is crucial to provide a high-quality photon beam to users because the mechanical motion should be maintained at less than 10% of the electron beam size which is expected to be sub-micrometer. One of the key roles of the girder is to provide structural rigidity and temperature stability while effectively suppressing vibrations from the ground during accelerator operation. The Korea 4GSR girder is being designed to have the first natural frequency above 50 Hz to minimize the effect of the ground vibration. In order to maintain better mechanical stability, it is necessary to conduct research not only on the natural vibration evaluation of the girder but also on external vibrations to the girder structure. In this paper, we introduce the result of the harmonic analysis of the girder structure using the finite element method.

Ensuring the mechanical stability of the girder for a 4th generation storage ring (4GSR) is crucial to provide a high-quality photon beam to users because the mechanical motion should be maintained at less than 10% of the electron beam size which is expected to be sub-micrometer. One of the key roles of the girder is to provide structural rigidity and temperature stability while effectively suppressing vibrations from the ground during accelerator operation. The Korea 4GSR girder is being designed to have the first natural frequency above 50 Hz to minimize the effect of the ground vibration. In order to maintain better mechanical stability, it is necessary to conduct research not only on the natural vibration evaluation of the girder but also on external vibrations to the girder structure. In this paper, we introduce the result of the harmonic analysis of the girder structure using the finite element method.
