Outer containment vessel, prior to final assembly.
Outer containment vessel, showing the baseplate prior
to installation of the window test modules.
Outer containment vessel, another view.
View through the lexan window, of the mounting
hardware for the window test modules. The optic axis is perpendicular to the
proton beam axis, and is primarly for the mercury tests.
The 5 double window test modules being installed in
the outer containment vessel. Each double window unit has a thermocouple
vacuum gauge protruding to the left, and a brass shutoff valve pointing
upwards.
Exploded drawing of a double window module.
Another view of the 5 double window test modules.
The 5 strain sensor modules, prior to final assembly.
Closeup view of the havar window + strain sensors.
The window is clamped between a pair of conflat flanges, and 4 fiberoptic
strain sensors are glued to the havar to form a kind of quadrant detector.
FISO fiberooptic strain sensors.
Another view of the 5 double window modules.
The four 18" extension tubes, prior to assembly.
Each has a double window module at one end.
Yet another view of the 5 double window test modules.
(Maybe the best view.) The two ports in the outer containment vessel for the
proton beam can be seen in the upper part of the picture.
Four strain sensor modules being mounted in proton line
2.
Completed assembly of 5 double window modules and
5 strain sensor modules. We are testing 0.010" Al, 0.011" havar,
0.013" Ti90Al6V4, 1mm inconel 718 and 6mm inconel 718. The proton beam will
enter from the upper right. Our line 1 contains the Al strain sensor + the
5 double window units; line 2 contains the havar, Ti and inconel strain
sensor modules.

The window test box on the x-y mover. The beam
flag is at left center; the SWIC (segmented wire ion chamber) and
picture frame loss monitor are at right center.

The Yokogawa digital scope used to read out the
strain sensors. DL700
specs.
Strain sensor data. Upper trace = the beam current
transformer just upstream of the target box. Lower trace = data from a
fiberoptic strain sensor on the aluminum test window. The horizontal scale
has been expanded to 500 ns/div. The beam arrived about 750 ns into the
frame.

The completed carbon rod assembly. Line 1 (lower)
contains two 12" ATJ graphite rods + strain sensors. Line 2 (upper)
contains a 12" ATJ rod + two 4" carbon-carbon composite rods. The proton
beam will enter from the right.

Carbon rod Strain data. Two sensors
located at the middle of a carbon rod, but on opposite sides, show 350 Hz
strain signals due to
transverse bending that are 180 deg out of phase. The higher frequency
components are due to longitudinal waves.
