Below brief description of topics is written together with incomplete
list of people focusing of a particular topic. These subgroups should
communicate and if po
·
Overview talk
(Optics, collimation, beam dumps, etc.)
ð Optics design,
collimation, final doublet, beam dumps
ð Considerations
for physics options and detector concepts parameter: length of detector times
solenoid field vs emittance
growth
ð e- e- /gamma-gamma collisions : disrupted beam, luminosity
(beam sizes, intensity)
ð Big bend
optimization to make performance of both IR as equal as po
ð Tests of
crab-cro
ð Investigation
of crab cavity location for 2-mrad x-ing;
ð Considerations
for collimation and backgrounds, deep collimation : small bore of permanent
magnet - large cro
ð pole tip
design of conventional magnet - small cro
ð shallow
collimation : large bore super Q - small angle cro
ð luminosity
loss by emittance growth at the collimation;
