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.

The storage of low current beams as well as the long extraction times from the synchrotrons at FAIR require non-destructive beam intensity monitoring with a current resolution of nanoampere. To fulfill this requirement, the concept of the Cryogenic Current Comparator (CCC), based on the low temperature SQUID, is used to obtain an extremely sensitive beam current transformer. During the last years, CCCs have been installed to do measurements of the spill structure in the extraction line of GSI SIS18 and for current monitoring in the CERN Antiproton Decelerator. From these experiences lessons can be learned to facilitate further developments. The goal of the ongoing research is to improve the robustness of the CCC towards external influences, such as vibrations, stray fields and He-pressure variations, as well as to develop a cost-efficient concept for the superconducting shield and the cryostat.

  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.
