- 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
