CH He3 Attenuation Measurements

• Build poly box to house source and help thermalize neutron flux

• Get Cf source

• Measure rates in He3 tube with differing amounts of poly (and different types) -> get to background levels
  • Thermalize neutron flux from Cf with virgin poly for all measurements
  • Build virgin poly box around Cf source
    • Pretty quick and dirty measurement to figure out which poly is best

Results

Completed attenuation measurements with differing thicknesses of Borated Poly vs unborated poly with and without BorAl.
