MOPB02 | ARIES-ADA: An R&D Network for Advanced Diagnostics at Accelerators | 71 |
|
||
Funding: This project has received funding from the European Union’s Horizon 2020 Research and Innovation programme under Grant Agreement No 730871. Accelerator Research and Innovation for European Science and Society, ARIES, is an initiative funded by the European Union (https://aries.web.cern.ch/). The activity comprises three major categories: Joint Research Activities; Transnational Access; Network Activities. One of these networks is related to Advanced Diagnostics at Accelerators (ADA) with the task of strengthening collaborations between international laboratories for coordinated research and development in beam diagnostics (https://aries.web.cern.ch/content/wp8). This task is performed by organizing topical workshops on actual developments and supporting interchange of experts between different labs. Since the start of the project in May 2017 four topical workshops of two to three days duration have been organized, each with 30-40 participants ranging from novices to worldwide experts in their particular field. In this contribution these initial workshops are summarized and an outlook given for further workshops within this ARIES-ADA network. |

WEPB14 | Recent Results on Non-invasive Beam Size Measurement Methods Based on Polarization Currents | 464 |
|
||
We present recent results on non-invasive beam profile measurement techniques based on Diffraction Radiation (DR) and Cherenkov Diffraction Radiation (ChDR). Both methods exploit the analysis of broadband electromagnetic radiation resulting from polarization currents produced in, or at the boundary of, a medium in close proximity of a charged particle beam. To increase the resolution of DR, measurements were performed in the UV range at a wavelength of 250 nm. With such configurations, sensitivity to the beam size of a 1.2 GeV electron beam below 10 um was observed at the Accelerator Test Facility (ATF) at KEK, Japan. In the case of the ChDR, a proof of principle study was carried out at the Cornell Electron Storage Ring (CESR) where beam profiles were measured in 2017 on a 5.3 GeV positron beam. At the time of writing an experiment to measure the resolution limit of ChDR has been launched at ATF where smaller beam sizes are available. We will present experimental results and discuss the application of such techniques for future accelerators. | ||

WEPB16 | Development of a Beam-Gas Curtain Profile Monitor for the High Luminosity Upgrade of the LHC | 472 |
|
||
High luminosity upgrades to the LHC at CERN and future energy frontier machines will require a new generation of minimally invasive profile measurement instruments. Production of a dense, focussed gas target allows beam-gas fluorescence to be exploited as an observable, giving an instrument suitable for installation even in regions of high magnetic field. This paper describes the development of a device based on these principles that would be suitable for operation in the LHC. It focusses on mechanisms for the production of a homogeneous gas curtain, the selection of an appropriate working gas and the optical fluorescence detection system. | ||
