While the taskforce continue work on the 2mrad optics with L*=4.5 capable
to go to 1TeV, and this may still take some time, this design optimization
should not delay calculations of background for the 2mrad case.
Complete simulations of background with good statistics and for
different IP parameters will take about 2 weeks. So, for example,
Takashi has to start these simulations literally now.
Also, evaluation of downstream diagnostics require simulations.
It is suggested, therefore, while the BDS design evolves,
to use the previous version of mid-June for background simulations
and diagnostics evaluation. This version was most complete and
included downstream diagnostics.
The optics is posted here http://www.slac.stanford.edu/~yuri/ILC/Decks/
files exline-20mr-050524.mad and exline-2mr-050613-turtle.mad
Please communicate to make sure that the same geometry descriptions
of the IRs, detectors, extraction line and diagnostics are used by all
people doing background studies.
