Description
Muon colliders offer enormous potential for research of the particle physics frontier. Leptons can be accelerated without being subjected to large synchrotron radiation losses. The International Muon Collider Collaboration is considering 3 and 10 TeV (CM) machines for a conceptual stage.
At the front end of the Muon Collider facility lays a MW class production target system, which will absorb a high power (1.5 to 3 MW) proton beam to produce muons via pion decay. The target must withstand high dynamic thermal loads induced by 2 ns high intensity pulses at a 5 Hz repetition rate. The target system comprises other critical components such as the proton beam windows, subjected to substantial radiation damage, and a surrounding 600 kW tungsten shielding to protect the magnets from neutrons and the electromagnetic radiation. Operational reliability must be guaranteed to reduce target exchanges to a minimum, in an area where all the systems will have to be integrated inside a SC Solenoid cryostat.
This contribution provides an overview of the target systems design and engineering assessments related to a carbon target baseline, along with alternative target concepts involving liquid lead and fluidized tungsten powder, for the International Muon Collider Project.
