About
Beam-intercepting systems are essential devices designed to absorb the energy and power of a particle beam. Generally, they are classified in three categories depending on their use: particle-producing devices, such as targets; systems for beam cleaning and control, such as collimators or scrapers; and those with safety functions, such as beam dumps or beam stoppers.
Beam-intercepting devices have to withstand enormous mechanical and thermally-induced stresses. In the case of the LHC beam dump, for example, upgrades of the LHC injectors will deliver a beam which at high energy will have a kinetic energy equivalent to 560 MJ during LHC Run 3, roughly corresponding to the energy required to melt 2.7 tonnes of copper. Released in a period of just 86 μs, this corresponds to a peak power of 6.3 TW or, put differently, 8.6 billion horse power.
The lectures will focus on the engineering activities regarding these devices, which consist in conceptual studies, material selection, prototyping and testing, R&D, design, manufacturing, installation and operation follow-up. Examples of recently developed devices will be shown, including fixed targets, collimators and dumps/absorbers to cope with LIU and HiLumi beams. Design work includes Monte Carlo (with code such as FLUKA) and Finite Element Analyses (FEA) to determine the behavior of the systems during beam impact, testing and prototyping activities to validate technical solutions, material characterisation and testing under beam, both single impact and long-term radiation damage.
Manufacturing, assembly and installation steps will be shown for some devices, including operation follow-up.
The challenges to be expected in the few years with the development and implementation of new machines will be also discussed.
