A Heavy Ion Monitor on a Chip Based on a Non-Volatile Memory Architecture

The performance of a particle detector derived from nitride read-only memory (NROM) technology is evaluated, with immediate applications in space-based heavy ion radiation monitoring and detection. Irradiation exposures are performed using 40 MeV/u $^{78}$Kr and 10 MeV/u $^4$He particle beams at the Texas A&M University Cyclotron Institute. The results show a strong sensitivity to high-Z heavy ions, and medium sensitivity to low-Z heavy ions.

Thermal Neutron Measurements with an Unpowered, Miniature, Solid-State Device

A prototype neutron detector has been created through modification to a commercial non-volatile flash memory device. Studies are being performed to modify this prototype into a purpose-built device with greater performance and functionality. This paper describes a demonstration of this technology using a thermal neutron beam produced by a TRIGA research reactor. With a 4x4 array of 16 prototype devices, the full widths of the beam dimensions at half maximum are measured to be 2.2x2.1 cm2.
