- 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
http://www.alibaba.com/product-gs/346924116/Tungsten_Disk_With_Screw.html
http://www.zlxtech.com.cn/products.asp?productcode=7401000404
http://www.cleveland-tungsten.com/
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.
