- Chriss Jackson's Positron Target development logbook
- Goal
- Construct a Tungsten target and vacuum enclosure to be used for generating positrons using an incident electron beam.
Geometry
Tungsten Disks
- Dimensions are in cm

If the motor has a radius of 2.5" and I want to shield the motor from the beam using 2" of Pb and the beam is about 1" in diameter then I want a Tungsten disk that is
5.21" in radius = 13.25 cm in radius ~ 30 cm in diameter
Target Chamber design
Latest Design From empire and Sadiq's measurement of the available space

| Target motor Design | Available beam line space | Motor axle coupling to rotary union | Hub and spline to attache targets |
Dimensions for the target chamber box. Measurements in inches. updated 11 May 2012. Holes for tubing still missing, need to measure.

The resolution in the above image makes it too dificult to read the numbers. See if you can upload a PDF version.
1.) Lid with a lip that bolts on.
2.) bolt pattern on the bottom for the motor mounts
3.) find cooling lines for inside the box
4.) Find elbows for the rotary unions.
. . . . 100.) Design a target mounting system
