US CMS EMU Introduction

• Fermilab has responsibility for the design and
  procurement of the components for all the CMS_EMU
  chambers
• Fermilab has responsibility for the assembly of
  the ME234/2 Chambers
• ME234/2 Subject of this Review
• ME2/1 Assembled at PNPI (Russia)
• ME3/1 Assembled at PNPI (Russia)
• ME1/2 Assembled at IHEP (China)
• ME1/3 Assembled at IHEP (China)
• Fermilab has responsibility for the shipment of
  kits and critical tooling to PNPI and China IHEP.

US CMS EMU Tooling Readiness

• Majority of the tooling in place and operated on
  many prototypes
• Missing Tooling
• Cleaning Machine
• High Pressure (100 psi) dry air line for the
  Ionized Air Cleaning
• Vacuum lifting device to transfer panels to/from
  the gluing machine
• Mechanical stands for final chamber HV testing
• Box for anode panel electrical testing

12
US CMS EMU Manpower

• Analysis of Manpower
• L2-L3 Managers
• 8 technicians needed on production floor
• Spit-ball 2 of the technicians are IHEP/PNPI
  visitors for training purposes (lower efficiency)
• Production Engineer
• 8 high-efficiency technicians needed on
  production floor.
• MP9 Floor Manager (G.Smith)
• As high as 12, with reasonable approach ( i.e.
  add people as necessary)

13
US CMS EMU Manpower

• Tooling Utilization/Contingency
• Goal 1 chamber/week _at_ full speed production
• No particular piece of tooling is used at 100
• Winding Machine 1 panel/3 hours
• Soldering Machine 1 panel/4 hours
• Hand Soldering 1 panel/5 hours
• Major bottlenecks are expected to be
  hand-operations
• Soldering
• Chamber Sealing Testing
• Chamber Repair
• Contingency Plan
• Increase manpower
• Second Shift

14
US CMS EMU Cost/Schedule Risk

• Chamber Integration
• Although the chamber design is complete, some
  electronic-chamber integration issues are still
  pending. None of these issues is a FNAL
  responsibility, but some of them may affect the
  chamber assembly at FNAL
• HV Cable/Electronics-Chamber grounding
• external mounting
• Frame Finalization/Chamber Faraday Cage
• Chamber dis-assembly
• The goal of the CMS-EMU Collaboration is the
  completion of integration by the end of FY 99
  (?).

15
US CMS EMU Cost/Schedule Risk

• Risk
• stop production for chamber reworking
• Schedule
• Worst case scenario stoppage 3-4 months
• 1 month design change
• 3 months procurement
• schedule may be recovered going to contingency
  plan
• second shift
• extra man-power
• Manpower
• During stoppage many subassemblies can be done by
  the MP9 work-force.
• Chamber rework is expected to be 20-30 of a
  typical chamber assembly time.
