Present and Future Efforts and IR issues

15-May-2003; This home page is slightly modified. Especially, "Present and Future Efforts" page is updated.
3-February-1999; The page is created.

This group consists of these people at present, and calling for new commers.
Interaction region is a place where a good communication between experimentalists and accelerator physicists is very important. The field is large from the exit of the main linac to the beam dump. The major issues are backgrounds related beams and stability of the beams for high luminosity.
Activities

Background calculation/simulation (synchrotron radiations, e+e- pairs, muons, neutrons, hadrons...)
Masking system around an interaction point (IP).
Collimation system at the exit of the main linac.
Final focus system.
Dump line including beam polarization/energy measurement system.
Instrumentation (beam position/profile monitor, fast feedback,....)
