The dwindling supply of He has necessitated the adoption of new technologies for detection of neutrons especially in Homeland Security (HS), where detectors require large volumes of the precious gas. The boron-coated straw (BCS) technology consists of very thin-walled metal tubes equipped with a highly robust coating of BC on the inner wall. The coating, applied with Physical Vapor Deposition (PVD), is atomically bound to the metal substrate, and it is able to resist delamination over a temperature range from C to 1000 C. Accelerated lifetime testing of sealed straw detectors over extreme temperature ranges ( C to C) have recently demonstrated a 99% expected lifetime of 30 years. At the same time, the coating purity is high, with a B content approaching 77%. Straws stacked 5 deep in a dense array have demonstrated an efficiency of when evaluated in a cold neutron beam. A number of field worthy HS detectors have been developed over the past 2 years based on the BCS. Examples are presented, including neutron modules for Radiation Portal Monitors (RPM), a vehicle mounted modular detector with an intrinsic efficiency of 30% for unmoderated Cf neutrons, and handheld detectors. All of these systems have been government tested. The BC coated straw offers a highly versatile, robust and low cost technology meeting multiple needs in homeland and international security.
