LB Feb Soil Information

Target Information

Target#170013-001 was simply soil placed in an aluminum cylinder with a mass of 32.65g, a diameter of 4.5cm and a height of 12cm.

Target 4	Mass (g)
Soil Mass	109.78

The soil was collected from the following gps coordinates

Beam Parameters

The sample was irradiated with 250Hz beam with [math] 90 \times 10^{-3} [/math] Amp current. The pulse width was [math] 4 \times 10^{-6} [/math] seconds at an energy of 20Mev = 1.44kW. The sample began irradiation at 8:00AM and was irradiated for 8 hours in the rotating sample holder, ending at 16:00 on 2/13/17.
