The idea is to layer thin films detectors onto an optically clear substrate material*. It is our first step toward a fabricated detector, and it looks good.

| Fabricated Detector. Thin films are sandwiched between glass slides |
 |
| Fabricated detector was wrapped in teflon tape to reflect light. |
 |
| Teflon tape was wrapped in light absorbent black tape to minimize light leaks |

Hopefully by the end of this week we can take one of the Cf-252 sources and actually mock up the DHS criteria to get an idea of detector performance.
*We made a serious design flaw in using off-the self microscope slides. We don't know how much boron is in them (most glasses is 5%), and boron-10 (a large neutron absorber) is 20% of natural boron. A better choice would be quartz, or a clear polymer that would further moderate the incident neutron spectra.
