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

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
