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 SqM Fast Site test room and supporting structure ready 8. Production Computers were connected to networking

Man Power for Mass Production 1.5 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

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 items 1.Budget Situation:Expensive test Gas Mixture requires more 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.Lab readiness for Mass Production

ONDJFMAMJJASONDJFMAMJJASOND Prod.Schedule Chamber Ass. Fast Site Ship Unit to CERN

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 Frame Manufacture-1

Frame Manufacture-2 ME1/2 Frame Drawing Questions Tope Big End: 1.4*M5 parts missing, 2.6*Phi0.44,at Prototype, only 4, 3.6*M6, no at prototype frame, 4.6*phi5.2,only 5 at prototype, 5.no consistent drawing with Prototype Bottom Big End 6*Phi0.44,at Prototype, only Top Small End: 4*Phi8,4*M6, no exist at prototype Top HV Side: 8*M6,4*M6 at Prototype,Phi no at Pro. 1 Full Rad Slot, 2 at Prototype Anode Side: No consistent with Prototype Top Anode Side:0.75wide*3.15Lg.Slot No consistent

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
