Detailed Design Drawing Report 6/27/08
Outline:
1.) Dimensions
2.) Constraints: Case 3 from progress report: constrain triangle and nose plate on upstream side.
3.) Deflection Analysis
Steps:
a.) check triangle contact region and its mass b.) add another carbon fiber rod c.) increase size of back plate
4.) Drawings
drawings in PDF format
a.) Endplate structural drawing (no holes just shaded area)
b.) Drawings for all other parts
c.) drawing showing how parts are bolted together
d.) Copy old R3 (take advantage of no curved window.
Report
Basic understanding
This section of the report will deal with the basic understanding of the region 3 in the nuclear Drift Chamber. This is where the required geometric parameters are understood.
Initial parameters to be followed to fulfill to satisfy design Criteria
1. Distance from target to first sense wire plane along a ray which is normal to the end plate = 4746.5 mm
2. Chamber Tilt Angle = 25 Degrees
3. Maximum Scattering Angle = 45.05 Degrees
4. Minimum Scattering Angle = 4.5 Degrees
5. Wires are at 6 Degrees to the horizontal in each of its wire planes
Assembly
The Assembly of each sector in the region 3 drift chamber can be considered similar to each other. Each assembly can be divided into sub-assemblies like
1. Nose Plate
2. Left End Plate
3. Right End plate
4. Back plate
5. Backing Sheet
6. Carbon rods
7. Attachments: These are the external geometric parts of each sector, used for clamping and mounting each sector. so, they might change with the orientation of each sector
A detailed drawing of this assembly can be viewed at File:Assembly20 jun 1.pdf
Nose Plate
Nose plate is the plate where both the end plates are attached to it on either side
A detailed drawing of Nose plate can be viewed at File:Assembly20 jun 2.pdf
Left End Plate
Left end plate is the end plate to the left hand side if we are viewing from the target. Left end plate and the right end plate are same with parts and its dimensions. However, the hole locations differ between each other.
Each end plate sub assembly consists of 3 parts, namely
Left end plate Core - made of Polyurethane 600 px
Left end plate Skins - 2 No's- Made of stainless steel 600 px
End plate casing - Made of Aluminum.
They can be referenced with left and right to show each sub assembly.
A detailed drawing of Left end plate Core can be viewed at File:Assembly20 jun 4.pdf
A detailed drawing of Left end plate skin can be viewed at File:Assembly20 jun 5.pdf
Since end plate casing will not have holes for wires, the drawing for left end plate casing and right end plate casing will be the same.

Right end plate
Left end plate is the end plate to the left hand side if we are viewing from the target.

Right end plate Skins - Made of stainless steel File:Assembly20 jun 8.png
They can be referenced with left and right to show each sub assembly.
