Actuated diagnostics present additional challenges that static diagnostics devices do not such as alignment, stability, and incorporating an appropriate drive mechanism. These challenges become even more apparent as the actuaded length increases. At the Facility for Rare Isotope Beams (FRIB) we plan on using a number of actuated diagnostics devices including a Profile Monitor (AKA: Wire Scanner) with 12 inches of actuation. The Profile Monitor uses tungsten wires to traverse the beam pipe aperture to measure the beam intensity with respect to it’s location in the X-Y plane. This paper will detail the design of the 12 inch Profile Monitor and how it is able to overcome the stability, alignment, and drive issues that come with the 12 inches of actuation.

  Due to the different beam diameters and the inclusion of superconducting cavities, different Beam Position Monitor (BPM) types with welded buttons are to be used in the Facility for Rare Isotope Beams (FRIB). The varying BPM sizes include the following apertures: 40 mm, 50 mm, 100 mm, and 150 mm. The 40 mm BPMs include both warm and cold types where the cold BPMs are located in cryomodules next to SRF cavities. Steel-jacketed SiO2 coaxial cables with sealed SMA connectors have been selected as signal cables in the cryomodule insulating vacuum. These will connect to the BPM assembly at roughly 4 K temperature at one end and to the feedthrough flange in the vacuum vessel wall at 300 K at the other end. The 40 mm and 50 mm BPMs will include 20 mm custom-made buttons. The 100 mm and 150 mm aperture BPM buttons will be larger, anywhere from 30 mm to 40 mm. This paper will specify the mechanical and electrical design challenges and the resolutions associated with FRIB operations in the following areas: varying BPM conditions, changes in apertures, and variants in button sizes.
