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
