Wide Angle Baffle at IXC

Links to knowledge

The cooling test
Wide Angle Baffle design review (Obuchi)
Requirements for heat links of WAB (Akutsu)
Temporal information links
Wide Angle Baffle assembly-procedure manual (Zeidler)
Calculations regarding the back-scattering of different Wide Angle Baffle designs (Zeidler)
Personal calc of WAB's stray light noise by Akutsu; due to several uncertain parameters there are several results and no one would know the actual effect!
Heat links positions (by Obuchi) fmkopgehpapgdkcc.png

Task list

Note: some of the tasks can be done in parallel.

Place/install the WAB suspension
Align the position of WAB -> take WAB back to nominal position, put off protectors
- horizontal alignment
- yaw alignment
Lift-up WAB by 1mm
Blow inside the WAB; put protectors and shield the aperture (foil?)
Clean area around chamber
Heat-Link adapter to WAB -> Needs to be designed (Akutsu/Obuchi)
Thermometer adapter to WAB

Pin Assignment

P23

Pin Name	Resistance	Equipment	Assign	Comment1	Comment2	Connection
A	75 ohm	Thermometer	V-	Green
B	75 ohm	Thermometer	V+	Black
C	4 ohm	Thermometer	I-	Red
D	4 ohm	Thermometer	I+	Yellow
E	75 ohm	Thermometer	V-	Green
F	75 ohm	Thermometer	V+	Black
G	4 ohm	Thermometer	I-	Red
H	4 ohm	Thermometer	I+	Yellow

Note that the pin arrangement (or the naming) is mirrored compared with that of in IYC! Rather, I guess this IXC's would be correct.
