Helium Box

| | Comments (0)

We are in the process of building a Helium box for the PX endstation. It has a lower and upper box. The lower box will be permanently affixed to the endstation, and the upper box will be removable. Although it is a little complicated to remove, it takes about 5 minutes to install/remove. I've posted a few pictures so you can get an idea of how it will work.

Helium box installed on the PX endstation. Some of the acrylic still has the brown paper protective sheets attached.

Looking through the exit window at the sample. The polyethylene film is not installed yet, but it will seal the window.

Another view with the beamstop/collimator stage in the UP position.

I still need to seal up the Phi hole...

... and the cryo hole.

And this gaping hole must also be sealed.

The Helium box has been designed so the polyethylene window can be easily slide upwards to allow access to the sample.

More to come
