X5A Hutch

Here is a photo of the X5A hutch, which is the NSLS Development and Instrumentation (DNI) hutch. The back part of the hutch still has the goniometer from when this was the Chemistry Division powder diffraction beamline. Since reverting to the light source about a year ago, it has mostly been used by Pete Siddons for detector development. The space in the upstream part of the hutch is where I propose to test the monochromator when it arrives from FMB-Oxford.

Here is a photo of the hutch taken on 12 January, 2009. Pete was in the process of setting up for one of his cultural heritage fluorescence mapping measurements. (I think he will be looking at a small, figurative Jackson Pollack painting.)

X5A is a white beam hutch. Upstream of the hutch there are slits and nothing else, so NSLS dipole radiation with the IR/VUV removed is entering the hutch.

All of the items in the upstream part of the hutch will be removed for the mono tests. That includes the blue table with the sample stage and oscilloscope, the cart with the computer, the turbo pump, and the stack of electronics between the blue table and the inboard wall.

From the beam entrance to the X5B beampipe at the point labeled "A", there is about 48 cm of usable space. The bracket circled in red is the nearest obstruction.
From the beam path to the X5B beampipe at the point labeled "B", there is about 61 cm of usable space.
The distance from the beam entrance to that big, klunky slit assembly (along the green line) is about 155 cm.
The big, klunky slit assembly and much of the stuff behind it (all circled in green) can be removed, adding up to 79 cm to the available path length.
From the beam path to the outboard wall there is about 210 cm.
The door is about 97 cm wide.

We propose to cap off the mono with Be windows on conflat flanges and to place the mono near the beam entrance. Downstream of the mono, we will somehow mount a couple of ion chambers. This should be sufficient to do delivery tests of the mono.
