	At the Australian Synchrotron (AS), the need for nondestructive X-ray beam positioning monitors (XBPM) in the beamline front ends led to the development and installation of an in-house prototype using the photoelectric effect in 2021. This prototype served as a proof of concept and an initial step towards creating a customised solution for real time X-ray position monitoring. Of the new beamlines being installed at the AS, the High-Performance Macromolecular Crystallography (MX3) and Nanoprobe beamlines require XBPMs due to their small spot size and high stability requirements. However, a significant hurdle is the short distance from the source point to the XBPM location, resulting in an extremely restricted aperture to accurately monitor the beam position. Scaling down the photoelectric prototype to accommodate the available space has proven challenging, prompting us to explore alternative designs that utilize temperature-based methods to determine the beam position. This paper details insights made from investigating this alternative method and design.

	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.
