For XTDX (In/Out movement)

example : T TDXMIO(1) >> 1 means Dump position = Safe

For XTDV (In/Out movement)

Protect People around beam areas by limiting their intensity

Declare the North Area SAFE or UNSAFE

North Area is SAFE if all beams are SAFE

North Area is UNSAFE if one beam is Not SAFE (cut SPS extraction)

A Beam is SAFE if :

Current in BENDS is limited (= beam energy limited)

OR

Elements on beam are in a position which limit its intensity

(Tax, micro-collimator.....)

A Beam is UNSAFE if its Intensity AND its Energy are not limited

LOKN
