Abstract
The Self-healing Autonomous Sensor Network (SASNet) is a prototype, wireless sensor network originally developed for the Canadian Army. The goal of the current work is to integrate a Radiological/Nuclear (RN) detector into the SASNet sensor nodes. The electronics were specially designed to ensure that the power consumption of the RN sensor will be very low (< 1mA); this will allow SASNet sensor nodes to operate remotely for many months on a single 3.5 V battery. The resulting printed circuit board (PCB) was designed to have the electronics and RN sensor package fit inside the existing SASNet node without modification to the form factor or enclosure. The RN sensor packages included a high-atomic number, high density scintillating crystal (bismuth germanate oxide, BGO, or lutetium yttrium silicon oxide, LYSO) and a silicon photomultiplier (SiPM). Vertilon Corporation was contracted to produce twelve prototype PCBs (six with LYSO crystals, six with BGO). Two of the units (one with LYSO and one with BGO) were evaluated at DRDC – Ottawa Research Centre with radioactive sources. This report summarizes these measurements. The PCBs were not integrated into the SASNet node at this time. This work will be performed in the future at Valcartier Research Centre (who lead the ongoing development of SASNet).
