WP2 is responsible for developing robust technical solutions to permit the extraction, transfer and safe delivery of the high intensity proton beam from the SPS to the BDF target in TCC8.
These solutions must also be compatible with the future operation of the North Area and the scope of consolidation foreseen as part of the NA-CONS project.
WP2 is responsible for collecting, defining and documenting the beam requirements before drafting and following up the functional specifications for the related accelerator systems needed as part of the high intensity upgrade, including:
- Beam instrumentation
- Magnets and power converters
- Machine protection
- Beam line vacuum
- Operational controls and tools
- Collimation
- Shielding improvements
The work package acts as a forum to review technical and functional specifications and to iterate the beam line design with all stakeholders, in particular the integration and configuration management teams, to finalise the engineering designs.
The modifications needed to bypass the T4 target station with the high-intensity BDF/SHiP beam in TCC2 are included in the scope of WP2 with the objective of commissioning TCC2 with high intensity after Long Shutdown 3 and before the readiness of the HI-ECN3 facility by using a new beam dump installed in the P42 beam line.
WP2 is actively invested in understanding operational performance of the North Area transfer lines and is responsible for carrying out related machine development studies, whilst providing the HI-ECN3 project support for beam tests of prototype extraction and target technology.
WP2 will also steer the SPS slow extraction R&D carried out over the last decade to a conclusion with operational systems dedicated for the application to BDF/SHiP. This includes operational deployment and commissioning of a crystal shadowing system in collaboration with the DECRYCE project to reduce the beam loss in the SPS extraction straight LSS2, along with the development and deployment of low-density electrostatic septa.
The specification and design of the BDF target dilution system is under the responsibility of WP2 to guarantee that the beam is always safely delivered on target.
The WP Leader and Deputy are charged with the coordination of the R&D effort as part of the Technical Design phase and to ensure, in collaboration with the HI-ECN3 project office, the delivery of the Technical Design Report and related Work Package descriptions to converge on an updated scope, with cost and resource estimates, and project schedule.
