Halo setting = 6. sigma (setting of primary collimator).
This case only includes a TCL in cell 4 of IR1.
The TCDQ in IR6 is made of two blocks. The TCTV in IR2 and IR8 are specific of one beam.

Halo setting = 6. sigma (setting of primary collimator).
This case includes TCLs in cells 4, 5, 6 and 7 of IR1 and IR5.
The TCDQ in IR6 is made of three blocks. The TCTV in IR2 and IR8 are specific of one beam.

Plots of the twiss function illustrating the specificities of the ATS optics: the trajectories and beta functions are different in the arcs surrounding the Interactions Points with low Beta* (IP1 and IP5).

The simulation results show loss clusters downstream IR7 at local inefficiency of around 105 m-1.
