**1.0 [General:]{.underline}**

> This specification defines the practices that the Fermilab Technical
> Division will follow in order to insure that each of the manufacturing
> sites that are involved with the CMS Endcap Muon Cathode Strip Chamber
> Production and Integration are kept informed of and can react to all
> Bill of Material (BOM), Engineering Drawing, Specification, and
> Traveler changes and revisions that eminate from Fermilab Technical
> Division.
>
> Fermilab will maintain copies of all Bills of Materials (BOM's),
> Engineering Drawings, and Specifications for all Endcap Muon Cathode
> Strip Chambers (ME 1/2, ME1/3, ME2/1, ME3/1, ME4/1, and ME234/2) under
> Configuration Control on its public web site shown below. It will also
> maintain on this site, production Travelers, as used in production at
> MP9, but only for the ME 234/2 chambers and only to the latest
> Configuration under Control. Fermilab will notify the designated
> contact person at each appropriate collaborating institution whenever
> any changes are made to the ME 234/2 chamber or that might affect a
> chamber for which they have some responsibility. Then it is up to each
> respective contact person, as named below, at each institution to
> review their own files and insure that their own documentation is
> brought up to date, where necessary, and kept current and consistent
> with the changes made at Fermilab and or with the appropriate approved
> Configuration.

**2.0 [Revisions Made to Basic Chamber Engineering Drawings,
Specifications, and Travelers]{.underline}**

2.1 Initial copies of released Engineering Drawings, Specifications, and
Travelers for ME 234/2, once brought under "Configuration Control", are
sent out to needing collaborating institutions on Compact Disc, and are
to be made available at the Fermilab, Technical Division designated Web
Site.

2.2 When revisions are made to drawings, specifications, or travelers,
an E-Mail memo is to be sent out according to the distribution list
shown below, notifying individuals on the distribution list of the
changes made. This memo will show the drawing, specification or traveler
number to which the revision applies, state the revision letter of the
new document to be used, and the effective date of the change. You will
also be reminded of the web address where the revised and updated
documents can be viewed and downloaded for your use. Copies of updated
documents will NOT normally be included as attachments to the revision
notice, unless special circumstances apply.

2.3 Files containing appropriate copies of Released Basic Chamber
Drawings and Specifications as represented by the most recent approved
Configuration Control Documents may be found at the following web site:

**<http://tdserver1.fnal.gov/project/UsCmsEmu/Released> Xxxxxxx**

2.4 Copies of the MP9 travelers for the most recent approved ME 234/2
Configuration under Control are kept at the following web site:

[**http://tdserver1.fnal.gov/project/UsCmsEmu/FNAL_Travelers/MP9_Travelers/
ME234-2_Travelers**](http://tdserver1.fnal.gov/project/UsCmsEmu/FNAL_Travelers/MP9_Travelers/ ME234-2_Travelers)

[Remember]{.underline}: It is up to each individual institution to
update their own drawings, specifications, and traveler files, as
appropriate to agree in principle with the FNAL documents for ME 234/2,
and to be consistent with most recent approved Configuration Control
Documents for a given chamber.

2.5 It is requested that each individual on the distribution list reply
to the sender of the memo, acknowledging receipt of the memo and stating
briefly the action that they will be taking as a result of the change or
revision notice.

2.6 Change Notice Distribution List:

**3.0 [Revisions Made to Integrated Chamber Engineering Drawings and
Specifications]{.underline}**

3.1 Initial copies of released Engineering Drawings and Specifications,
once brought under "Configuration Control", are to be sent out to
requesting collaborating institutions on Compact Disc, and are to be
made available on the Fermilab, Technical Division designated Web Site.

3.2 When revisions are made to these drawings and specifications, an
E-Mail memo is to be sent out according to the above distribution,
notifying individuals on the distribution list of the changes made. This
memo will show the drawing number to which the revision applies, state
the revision letter of the new document to be used, and the effective
date of the change. You will also be reminded of the web address where
the revised and updated documents can be viewed and downloaded for your
use. Copies of updated documents will NOT normally be included as
attachments to the revision notice, unless special circumstances apply.

3.3 Files containing current, up to date copies of Released Integrated
Chamber Drawings may be found at the following web site:

**<http://tdserver1.fnal.gov/project/UsCmsEmu/Released> Drawings/Chamber
Integration Drawings**

[Remember]{.underline}: It is up to each individual institution to
update their own drawing, specification, and traveler files, as
appropriate to agree in principle with the current up to date FNAL
documents for ME 234/2. Fermilab will not produce any Travelers for
Chamber Integration activities.

3.4 It is requested that each individual on the distribution list reply
to the sender of the memo, acknowledging receipt of the memo and stating
briefly the action that they will be taking as a result of the change or
revision notice.
