stress analysis with weird dimensions no. 2

the wall thickness of the chamber is 3mm. the factor of safety (FOS) is 3.5. (>2 is ok.) max. displacement is 238um.

stress analysis with weird dimensions

here is what happens to the top if we put 1atm (i.e. pumped chamber) onto the top. max. displacement is 34um. i have stabilized it with supports, which also can be used for removing the top (note the holes in the supports).

n.b.: you get a larger picture when you click on it.

refocusing optics in chamber

i got a question from livermore, if refocusing optics would fit into the zeppelin chamber. in the upper left corner, my problem can be seen.

130mm is the distance for the livermore experiment top flange-interaction region.
100mm is the distance interaction region-beamline port.
the beamline port (1inch: 35mm) is as far out as possible on the 16inch: 360mm chamber flange. nevertheless i lack about 10mm for the beamline port to reach up to the interaction region.

the question is if we could rebuild the livermore experiment, so that we can support it from the support rails instead. then we have no problem fitting both the refocusing optics and the livermore experiment into the chamber.

change of name x2

1) the free electron laser in hamburg was renamed on the 6th of april to FLASH (Free electron LASer in Hamburg). a great, funny name.
2) the uppsalachamber (see post below) is hereby baptized to Steel Zeppelin.

max. symmetry:
two sets of four flanges (1x200; 3x 250): experiment can be set 200, 400 600 or 800mm from beamline flange.

the to allows either
1) max. accessibility: remove the elongated top or
2) standard flange access.

two supports along the chamber allow for flexible mounting of experiments.
