1.0 General Notes

1.1  White (Lint Free) Gloves (Fermi stock 2250-1800) or Nitrile Gloves (Fermi stock 2250-2040)

or equivalent, shall be worn by all personnel, as required, when handling all product parts after

the parts have been prepared/cleaned.

1.2 All steps that require a sign-off shall include the Technician/Inspectors first initial and full last name.

1.3 No erasures or white out will be permitted to any documentation. All incorrectly entered data shall be corrected by placing a single line through the error, initial and date the error before adding the correct data.

1.4 All Discrepancy Reports issued shall be recorded in the left margin next to the applicable step.

1.5 All personnel performing steps in this traveler must have documented training for this traveler

and associated operating procedures.

1.6 Personnel shall perform all tasks in accordance with current applicable ES&H guidelines and those

specified within the step.

1.7  Cover the panel/chamber with Mylar when not being serviced or assembled.

1.8 Never hand pass anything over a panel as dropped items may damage the panel.

2.0 Parts Kit List

2.1 No Parts Kit Req’d

3.0 Chamber Transport

Completed

3.1 Transport the ME234/2 Chamber (MD-368220) using the Chamber Panel Cart (MD-368840) r

to the Chamber Capacitance Testing Station.

Note:

Position the Chamber in a horizontal position with gas tubes to facing upward.

3.2 Remove the Big End Panel (MC-368073) from the Chamber Wide End Frame r

Assembly (ME-368229).

3.3 Calibrate the Inter-Strip Capacitance Meter in accordance with Section 3.3 of the r

Inter-Strip Capacitance Operating Procedure 5520-OP-333472.

Note:

Inter-Strip Capacitance Calibration needs to be performed only once a day

before taking data.

Calibrating Set / Pass / Fail
Set – I
Set - II

Technician(s) Date

3.4  Measure the Inter-Strip Capacitances of each panel assembled into the Chamber beginning

with the Upper Cathode. Repeat this for each of the six planes/panels to be measured.

Note:

1.) Each Plane/Panel will have five (5) connections necessary to complete a

plane/panel measurement.

2.) Ensure Ribbon Cable Connectors are installed in accordance with the

below diagram.

3.) The Lower Cathode does not have 34-pin connectors and cannot be tested.

Plane / Panel / Completed
#1 / Upper Cathode
#2 / Anode
#3 / Inner Cathode
#4 / Anode
#5 / Inner Cathode
#6 / Anode

Technician(s) Date

Completed

3.5 The Chamber Capacitance Testing Technician must complete the following:

Record the Computer File Name r

Print a copy of the Chamber Capacitance Testing Report and r

attach it to this traveler.

Record the number of Testing Report pages attached r

to this traveler.

Technician(s) Date

3.6 Verify the Chamber is acceptable to proceed by reviewing the attached Chamber Capacitance

Testing Report.

Chamber Acceptable to Proceed r YES r NO

If NO, explain:

Assembly/Designee Date

3.7 Re-Install the Big End Panel (MC-368073) from the Chamber Wide End Frame r

Assembly (ME-368229).


Completed

3.8 Place the Anode Side Panel Skin (368105) onto the Anode Side loosely. Connect the r

two AFEB Alignment Gages according by diagram below. Center the holes on the Anode side

Panel with the holes on the AFEB Alignment Gages. If the holes do not line up, record the

difference in the space provided below by fourths. Once the holes of the AFEB Alignment Gages

and the Anode Side Panel lines up; tighten the bolts on the Anode Side Panel to the chamber.
