	In the framework of the High-Luminosity Large Hadron Collider project at CERN, a Full Remote Alignment System (FRAS) is under development, integrating a range of solutions for the remote positioning of accelerator components. An important component of FRAS is the motorized actuator allowing the remote adjustment of accelerator components with a micrometer resolution. These actuators need to fulfill multiple requirements to comply with safety rules, and be highly reliable and maintenance free as thus are located in a harsh environment. The integration of the safety functions required for the FRAS was crucial, with the motorized actuators able to provide an absolute position monitoring of the available stroke, integrating electrical end-stops and having an embedded mechanical stop as a hardware safety layer. In addition, the design has been elaborated to allow a rapid, in-situ readjustment of the nominal stroke in order to cope with potential readjustment requirements, following long-term drifts caused by ground motion. This paper describes the design approach, prototyping and qualification of these motorized actuators.

THOAM02	SmarGon MCS2: An Enhanced Multi-Axis Goniometer with a New Control System	247
	W. Glettig, D. Buntschu, E.H. Panepucci, M. Wang PSI, Villigen PSI, Switzerland A. Omelcenko SmarAct, Oldenburg, Germany
	As an improvement on the commercially available SmarGon multi-axis goniometer (SmarAct GmbH), the MX Group at the Paul Scherrer Institute (PSI) has been pursuing further development of the system. In addition to suggesting mechanical improvements to SmarAct to improve ruggedness and reliability, PSI has developed a brand-new and flexible control system for better customization, reliability and control. Calibration routines were implemented to reduce systemic errors, and the system has been tailored for practical beamline usage. SmarGon is a six degree-of-freedom positioning device, allowing positioning of a sample and orientation around any given point, with <5um sphere of confusion diameter. It was purpose-built for protein-crystallography experiments but, as will be presented here, was also re-purposed for other applications. Two devices have been in continuous 24/7 use for two years at the MX Beamlines PXI & PXII at SLS.

THOAM03	Magnetically Levitated 6 DoF Controlled Sample Manipulator for Tomography
	T.A.M. Ruijl, R. Faassen, L. Koorneef, D. Laro, W. Pancras, M. Princen, M. Wijnhoven, P. Wullms MI-Partners, Veldhoven, The Netherlands
	Tomography is a crucial imaging technique in modern synchrotrons. The latest, 4th generation, offers nanometer imaging resolution and fast data acquisition. However, existing sample manipulators mostly rely on quasistatic actuation principles and are constructed by stacking straightforward 1 DoF stages. Such stacking lacks the required dynamics performance and precision. To fill this need, MI-Partners developed a fully actively controlled (6 DoF) sample manipulator based on electro-magnetic actuation and a metrology system that ensures nanometer precision. It provides translational motion with a stroke of 3 mm and endless continues rotation around the vertical axis for full 360-deg angular tomography reconstruction. The novel actuator configuration has a circular magnet yoke which creates a radial polarized magnet field. Multiple sets of coils, acting as individual 3 phase motors, enabling independent control of 3 vertical and 3 tangential forces. The metrology system includes a tracking intermediate metrology frame. A set of capacitive sensors and interferometers enabling full 360 deg. rotation while allowing 3 mm radial movements and still reaching nanometer precision.

	Funding: This work is supported by the project of High Energy Photon Source (HEPS). High Energy Photon Source (HEPS) regarded as a new 4th generation synchrotron radiation facility, is under construction in a virgin green field in Beijing, China. The X-ray optics/mirror mechanical systems (MMS) play an important role, which would be expected to be designed carefully and rigidly for the extremely stable performance requirement of HEPS. In addition, there are indeed big challenges due to so many types of mirror systems, such as white beam mirror (WBM), harmonic suppression mirror (HSM), combined deflecting mirror (CDM), bending mirror, Nano-KB, and the transfocator of Compound refractive lens (CRLs), etc. Therefore, overall progress on design and maunfacturing of the MMS is introduced, in which a promoting strategy and generic mirror mechanical system as a key technology is presented and developed for the project of HEPS. Furthermore, ultra-stable structucture, multi-DOF precision positioning, Eutectic Galium Indium (E-GaIn)-based vibration-decoupling watercooling, clamping, and bending have always been prior designs and considerations.

THOAM05	Modeling the Disturbances and the Dynamics of the New Micro CT Station for the MOGNO Beamline at Sirius/LNLS	256

	Funding: Ministry of Science, Technology and Innovation (MCTI) At the 4th generation synchrotron laboratory Sirius at the Brazilian Synchrotron Light Laboratory (LNLS), MOGNO is a high energy imaging beamline, whose Nano Computed Tomography (CT) station is already in operation. The beamline’s 120x120 nm focus size, 3.1x3.1 mrad beam divergence, and 9·10¹¹ ph/s flux at 22-67 keV energy, allows experiments with better temporal and spatial resolution than lower energy and lower stability light sources. To further utilize its potential, a new Micro CT station is under development to perform experiments with 0.5-55 um resolution, and up to 4 Hz sample rotation. To achieve this, a model of the disturbances affecting the station was developed, which comprised: i) the characterization and simulation of disturbances, such as rotation forces; and ii) the modeling of the dynamics of the Micro-station. The dynamic model was built with the in-house developed Dynamic Error Budgeting Tool, which uses dynamic substructuring to model 6 degrees of freedom rigid body systems. This work discusses the tradeoffs between rotation-related parameters affecting the sample to optics stability and the experiment resolution in the frequency domain integrated up to 2kHz. N. L.
