Prod.Lab readiness for Mass Production

5. 6 Critical Tooling Operation Menus in Chinese ready at needed places

6. Travelers translated into Chinese and copies at each process room

Prod. Lab Readiness for Mass Production

7. 130 SqM Fast Site test room and supporting structure ready

8. Production Computers were connected to networking

Man Power for Mass Production1. 5 new hired Technicians were trained during the ME1/2

ME1/3 Prototype production, working on panel clean,gluing,hand soldering

2. Critical Tooling used by trained engineers, like Winding Machine

3. Quality Control by Engineers and Physicists(Only part time working on CSC)

4. Will have Ph.D students join the Tension Meas. And HV training soon

5. Final Assembly by Engineers


Prod. Lab Readiness for Mass Production

Quality Control and Tech. Ready

1. ME1/2 and ME1/3 prototype successfully assembled,Tension,Pitch, HV training,leak test meet requirements(low Leak and dark current,no trip for 58&43 Hrs at 4KV)

2. Strict work process according to Travelers

3. Key persons at each step to control quality

4. Good Lab management fits the quality requirements

Other items1. Budget Situation:Expensive test Gas Mixture requires mo

re money(CF4 imported fromUS, Complicated Chamber Packing Wooden Boxes--expensive,Shipping fee by Sea container more expensive than to US(land trans.)

2. Shipping Custom formality : Three Months effort, US Consulate Great Help. More effort needed from FNAL side for doccumentation(take as scientific Gifts)

3. Frame Manufacture: More machine budget and manpower paid from IHEP

4. Fast Site manpower and Instrumentation budget not enough

Prod.Schedule

Chamber Ass.

Fast Site

Ship Unit to CERN

2001 2002 2003

Key points to keep the schedule

1.Material arrives on time

2.Documents well prep.for Custom all the time

3.More training for fast team work

Frame Manufacture-0

Receive the drawings and extrusion material from FNAL

Responsible Engineer Mr.WEI

Drawing translated to Meter System and Chinese

FeiHong company will manufacture Frames

Needed technology tools were discussed and 29 kinds

jigs should be made to keep the quality

In two months the FeiHong company could deliver the

Frame parts to IHEP when Money and Material arrive

Summary

• Production Lab is ready

• Technicians trained, another 7 full working persons needed

•Budget may not enough(Gas, Shipping…

• Shipping schedule should be

on time to keep Prod. speed
