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 Amp current. The pulse width was 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.
