[Solid_ec] Fwd: [Sbs] Presentation possible parasitic measurement during GMp

[Cunfeng Feng]

Sorry for my worse link.

About the fiber. If we hold one bunch of fiber and polish them together, 
it  conviences to polish. But it will be difficult to insert all of them 
together into the detector, and some fiber can't reach the end of the 
detector if we cut them at same length. Also we should straighten the 
fiber, so it will be easy to instert. But how to straighten the fiber?

If we insert the fiber before bounding the fiber, it will be difficult 
to polish the end which coupled to the PMT.

 From ALICE's document, they divide the fibers into 4 bounch (not 1 
bounch) before insert, and the fiber is straight.
