Deformable optics, including mechanically-bent and bimorph mirrors, are essential optical elements for X-ray beam dynamical focusing and wavefront correction. Existing mechanical bender technology often suffers from poor repeatability and does not include twist compensation. We recently developed an elliptically bent mirror based on a laminar flexure bending mechanism that yielded promising results*,**. In this work, the mirror surface twist was characterized using a Fizeau interferometer under different bending conditions. By applying a shimming correction, the surface twist was successfully reduced from 50 urad to 1.5 urad. The twist angle variation from no bending to the maximum bending is less than 0.5 urad. Our simulation results show that these numbers are significantly lower than the required values to ensure optimum optical performance. The study demonstrates the effectiveness of the twist compensation procedures and validates the mirror bender design parameters.

  As part of the LEAPS*-INNOV** pilot project, Task 5.2 is dedicated to interferometers based online metrology developments applied to photon science instrumentation. One of the main objectives of Task 5.2 is to explore and develop the possibilities offered by interferometers (in particular fiber connected systems) to measure the sample position and its motions during typical synchrotron experiments. This four year program started in April 2021, with the participation to Task 5.2 of ALBA-CELLS, ESRF, HZB, PTB and SOLEIL. The objective of the poster is diffuse information on Task 5.2 current plans and to gather information on existing / on-going works and possible collaborations in the field of interferometers based metrology. *LEAPS: The League of European Accelerator-Based Photon Sources **LEAPS-INNOV is a pilot project submitted in reply to the INFRAINNOV-04-2020 European Union call for the implementation of open innovation and new strategies and tools for partnership with industry within the photon science community. It involves in particular the European synchrotron radiation light sources and free electron laser large-scale research infrastructures.

TUPC06 A Review of Ultrasonic Additive Manufacturing for Particle Accelerator Applications 185
  • J.A. Brandt

  Additive manufacturing (AM) technologies have been used for prototyping and production parts in many industries. However, due to process limitations and the unknown material properties of AM parts, there has been limited adoption of the technology in accelerator and light-source facilities. Ultrasonic Additive Manufacturing (UAM) is a hybrid additive-subtractive manufacturing process that uses a solid-state ultrasonic bonding mechanism attached to a CNC mill to join and machine metal parts in a layer-by-layer manner. The solid-state and hybrid nature of UAM ensures base material properties are retained and mitigates process limitations which traditionally inhibit integration of parts produced by other AM processes. This paper presents a review of the UAM process and its potential application to accelerator and beamline needs. Several specific areas are discussed including: replacement of traditional manufacturing approaches, such as explosion bonding to join dissimilar metals; improved internal cooling channel fabrication for thermal management; and imbedding of electronics and materials for more accurate remote sensing and radiation shielding.

TUPC07 Utilizing Additive Manufacturing to Create Prototype and Functional Beamline Instrumentation and Support Components 189

The world of beamline science is often fast-paced and dynamic. One of the major challenges in this environment is to be able to design, manufacture and then implement new items for use on the beamlines in a fast and accurate manner. Many times, this involves iterating the design to address unknown or new variables which were not present at the beginning of the project planning task. Through the use of additive manufacturing, I have been able to support the user programs of various (APS) Advanced Photon Source beamlines* across multiple scientific disciplines. I will provide a few detailed examples of Items that were created for specific beamline applications and discuss what benefits they provided to the pertinent project. I will also talk about why choosing consumer-level printer options to produce the parts has been the direction I went and the pros and cons of this decision. Primarily, this choice allowed for quicker turnaround times and the ability to make more frequent changes in an efficient manner. Currently, we are utilizing only the fused deposition modeling (FDM) type printers but I am exploring the addition of UV-activated resin printing, exotic materials that can be utilized using the current toolset, and the possibility of commercial metal printing systems. This technology has been a game-changer for the implementation of new support items and instrumentation over the last couple of years for the different disciplines I am supporting. I will discuss how the roadmap ahead and what the evolving technologies could potentially allow us to do.

  Scientific instruments and utility equipment during the operation of high radiation facilities such as the Advanced Photon Source at the Argonne National laboratory express a challenge to monitor. To solve this, we are developing a self-guided artificially intelligent robot that can allow us to take images to create a thermal and spatial 3D map of its surroundings while being self-driven or controlled remotely. The overall dimension of the robotic vehicle is 20 in length, 7 in width, and 10 in height, which carries a depth perception camera to guide the path, an IR camera for thermography, as well as a cluster of sensors to assist in navigation and measure temperature, radiation, and humidity of the surrounding space. This inexpensive robot is operated by an Nvidia Jetson NanoTM. All controlling and image acquisition programs and routines are written in python for ease of integration with institution-specific operating systems such as EPICS.
