【 摘 要 】

A detector was developed and funded by DHS to be a lower cost alternative to ³He detectors. A ⁶Li foil-lined ionization chamber was prepared with fill gas at one atmosphere and pulse mode operation. The high-density polyethylene (HOPE) body serves also as a neutron moderator. All electrodes, including high voltage bias supply, are hermetically sealed within the plastic slabs.
