[dsg-eic_dirc] EIC-DIRC as built survey of foam padding.

[George Jacobs]

I have a question about the gas system. What is the purpose or function of the individual check valves used on each air spring?

Tyler,

I just sent you a Google drive link to a place that Greg was collecting this documentation.  We uploaded a bunch of stuff there about a year ago.

You can see:

GAS SYSTEMS.pdf

This should be a rough schematic of the air spring suspension system.  I don't think you need the "nitrogen purge system", so just the first page of that is relevant.

There are some other photos.  I can ask John if he has a mechanical drawing of the little brackets that attach the dampers.
