Irradiation Data

Accelerator was on for 8 hours and turned off at 4:02 pm

Here are the specifications on the soil and selenium targets

Target Prep February 2017

Simulations

Selenium Irradiation Setup for MCNP simulations:

SeSetup.jpg

Flux

MCNP results for photon flux through the samples (electron beam energy is 21 MeV, energy bins are 100 keV, selenium density is 4.2 g/cc, selenium sample is cylindrical, 2 cm in diameter, 2 cm in height):


The selenium disk has a diameter of 0.5 cm and a thickness of about 2 mm
