Here is the drawing file of the Zeppelin chamber that I have sent to Allectra. Production time is 10 weeks, so we can expect to have the chamber delivered at the end of September.
On the drawing at least 1 source of potential confusion can be seen:
1) According to Henry Chapman, the submicron optics will be placed 100mm off-axis, 250mm downstream the chamber. So the submicron plane would be 220+250=470mm from the front flange. I have instead put it slightly off: at 445mm. It is a compromise, with a submicron plane at 400, we could use the submicron optics pointing towards the interaction region IAR670. Now the viewports can be used for both possible geometries.
In an earlier version of this blogpost, a second potential source of confusion was mentioned, but since then the interaction regions IARs were set to be centered with the CF360 flanges, simply to minimize confusion.
The definite geometry of the rails will be postponed until I have interacted more with the people constructing the parts to mount there.
I can send you eDrawings, DXF, DWG, etc. files on the chamber if you want to have a closer look. Last minute changes are welcome until Thursday the 13 of July.
