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.
