5. *) Intensity is for 1% momentum bite, nominal target and
not used in 2011
*) Intensity is for 1% momentum bite, nominal target and
ppp on target and intensity collimator(s) wide opened.
Spill 400 ms (could be > 500 ms at 20 GeV/c)
Some more intensity control exists for the primary beam ( ) and via the target efficiency (~ ).
