Outlook
Derived from our experience for TPC Production,
after some Modification of Tools we approached
the Production Mode to build 2 TRD Chambers / 7
Working Days Issues of the Design, mass
Production, Quality Control, system assembly and
testing of this large and complicated detector
system are very important to guarantee a good
quality of the whole system.
