• QA/QC meetings
– Regular meetings
• Vidyo (face-to-face if needed)
• Frequency: every 2 weeks
– Specific meetings
• As often as needed for discussions on specific topics (in particular with
other groups)
• First meeting yesterday

Mandate
From Mauro and Fabien
Scope : The QA/QC here addressed mainly concern construction but
not PCB QA/QC which is taken in charge by a different group. A link
between these groups must be established.
1.
Identify all individual components/parts to be labelled, recorded,
individually tested and the parameters that should be recorded.
2.
Identify checks needed during construction
3.
Establish methods for the quality follow-up during the
construction of the different parts at each construction site.
4.
List the parameters and results of the checks to be recorded.
5.
Establish the manual for the quality at the different phases of the
modules construction.

Mandate consolidation (1/)
• Implicit objectives:
Identify & if possible define all the QA/QC tasks
to be done during the construction
– to help defining all resources needed at construction sites
• “Construction”
??? (@ supplier
subsidies)
Delivery
from
« suppliers »
Storage
Assembly
Validation
Packaging
Shipment to
CERN
??? (@
CERN)
Including checks, qualification and overall management
Questions for consolidation :
- Items (except RO PCB) @ supplier subsidies (before delivery) to be considered?
- Some operations @ CERN to be considered?
- Limit with the services?
Be sure that QA/QC perimeter is not overlapping the one of another group

Mandate consolidation (2/)
1/ Identify all individual components/parts to be labelled, recorded,
individually tested and the parameters that should be recorded.
• Data needed:
List of parts &
components
Data needed by
physics

traceability rules
Check already
identified

Mandate consolidation (3/)
2/ Identify checks needed during construction
• Minimum list of checks asked by NSW-MM @ each construction site, to
assure that module requirements are fulfilled
• QA/QC group may suggest methods and instruments to do the checks.
– The collaboration defines and qualifies the way and means to do the checks.
• Data needed:
Product to be
tested
List of parts &
components
Product parameters to
be recorded
General operation scheme
@ construction sites
Best practices &
standards
Risks &
acceptability

Tasks & work organization preview
• Consolidate the perimeter (no overlapping
with other groups)
• Define tasks
• Define a schedule
– Objective : work in parallel (fast track)
• Define the groups in interface
• Dispatch the work

First ideas (1/2)
• Preparation of a list of the requirements to be fulfilled in each
test.
– From the WG on the requirements (planarity of the panels and positioning
during the assembly).
– From CERN rules (limits on the gas leaks? Other?)
– Criteria for testing the mesh before gluing, for cleaning, for testing the
tension.
– Geometrical and mechanical tests on the single panel and on the assembled
chamber.
• Methods and instruments for the test.
– For planarity: CMM machine, laser tracker, others?
– For Mesh test: ………..
– For gas leaks: decrease in time of a small overpressure? Leak test with a He
based leak detector for instance? Gas sniffers?
– etc.

12
First ideas (2/2)
• Definition of the tests needed during the different
steps of the MM chamber construction.
1) Test of the components (thickness of : pcb for drift panels,
honeycomb, frames etc.; test of the mesh, of other components)
2) Test during and at the end of the panels constructions (planarity,
stiffness of the panel, mesh tension, deformations, …)
3) Test after the assembly (geometry, tightness of the chambers – gas
leak, high voltage current leak, X-ray scanning )
4) Final test (radioactive source, cosmic ray)
5) Test of sensors (B field sensors, alignment sensors, etc.)
• Test in the construction sites (gluing farm,
assembling farm) and at CERN before mounting on
the NSW frame.
