Chambers RD

• Chamber Assembly
• Need
• Evaluation of flatness
• Plane Gap Uniformity (/- 12 mils)
• Dry Assembly of M234/2 Pro-production Prototype
• Test of Assembly Table
• Chamber Deflection in Horizontal Vertical
  Position
• Effects on Plascore Specifications
• Wire Quality
• Luma vs. Sylvania just started, presentation on
  D0 gold flaking problem
• Panel Cleaning
• Machine Needs in progress

Chambers RD

• Panels Measurements
• Panels flat of a 5x10 granite table under their
  own weight
• Measured bowing in the y (acceptable) and x
  (un-acceptable) directions

4
Chambers RD

• Chamber Sagging
• Final Assembly
• bottom panel straight (5 mils)
• top panel sags (70 mils)

5
Chambers RD

• Chamber Sagging
• Buttons-Gap Bars difference

374 mils
Still 30 mils unexplained
6
Chambers RD

• Panels Deformation
• We believe the PLASCORE panels we are working
  with have a 1/32 (20-30 mils) bow in the 5
  direction
• String Measurements on free standing panels.
• Laser Tracker measurements on granite table (see
  slide)
• Under gravity, for a single panel sitting on the
  gap bars
• Q Which kind of force is a sagging panel
  exerting on the next lower panel through the
  button ?

Sag (0 mils)
Sag (40 mils)
7
Chambers RD

• Panels Deformation
• Measured the displacement vs. force for a panel
  surface by pulling or pushing close to the button
  hole location (for both orientations of a panel).
  
• For small displacements 1 lb./1 mil
  elastically
• Q Which kind of deformation do we have close to
  a button hole for forces of the order of
  10-20 lb. ?
• Instron Measurements at TD Material Lab

8
Chambers RD

• Grooves Depth
• Issue
• Avoid skips during the machining of the panels
• Grooves of different depths are exposing
  approximately the same amount of G10 fibers
• Panels with grooves of different depths have the
  same mechanical strength.

9

  the information provided to FNAL

12
Procurement Status

• Major/Critical Procurements
• PLASCORE Panels
• Requirements and Specifications Understood..
• Available Panels
• Fail our specs in a single panel measurements
  on a granite table.
• Sagging problems in gap bars constrained
  configuration prevented us from measuring a 10
  mils bowing over 2 feet.
• the Receive Wisconsin frames drawings by end Sep.
  98
• Visit to PLASCORE (Aug. 98)
• PLASCORE has no tooling for QC. FNAL will provide
  it ( Sep. 98)
• PLASCORE identified 3 areas of possible
  improvements
• Core Cutting on 5 feet wide table
• Core Thickness measurement
• Control of the area of pressure on the Gluing
  Press
• Will order 14 panels with the above-mentioned
  improvements

13
Procurement Status

• Major/Critical Procurements
• Wire
• Specification writing based on D0 experience.
• RD on 1-2 Gold-Tg SYLVANIA wires.
• RD of flaking gold ? Which QC/QA does LUMA apply
  ?
• Good QA Plane needed.
• Panel Cleaning Machine
• Impossible to do RD on final chamber
• Will make systematic measurements on interstrip
  resistance and water retention on sample panels.
