FLUKA simulations of asynchronous dump in HL-LHC

• machine configuration:
  
• 7 TeV,
  
• beta*=15cm, optics version HL-LHC 1.2,
  
• TCTs opened to be on the limit of protecting the triplet - 13.3 sigma
• Assuming dump protection is misaligned and single bunches can directly hit the TCT4 or TCT5. Magnetic tracking from dump kicker of miskicked bunch to the TCT
  
• Several cases considered: 
• Grazing impact (center of the bunch at the edge of the jaw, so that half of the bunch hits the TCT) or full impact at a depth of 2 sigma
• Bunch hitting either TCT4 or TCT5
• Different materials: Inermet180 (present material, tungsten alloy), copper diamond, molybdenum graphite
• Shower simulated with FLUKA from TCT, particles written out at interface plane at 22.6 m
  
• Cutoff at 1 MeV for hadrons and muons, 100keV for photons and e-,e+, neutrons transported down to thermal.

Data files with particles entering the interface plane:

• IR5 B2, impact on TCT4. FLUKA simulation done by A. Tsinganis, F. Cerutti, tracking inputs and scenario by R. Bruce
  Normalization: 30000 events simulated in FLUKA, corresponding to:
• 1.167E11 real protons for the half bunch impact => One event in FLUKA corresponds to 3.889E6 real protons on the TCT
• 2.184E11 real protons for the full bunch impact => One event in FLUKA corresponds to 7.280E6 real protons on the TCT

Data files:
• Particles at the interface plane for half bunch impact on Inermet jaws
  
• Particles at the interface plane for half bunch impact on molybdenum graphite jaws
  
• Particles at the interface plane for full bunch impact on molybdenum graphite jaws
