Abstract

Our previous studies reported on the development of directional sensors for gamma and x-rays that have an angular resolution of one second of arc and are limited only by the accuracy of our measurement of the angle. Those sensors produced response functions that looked like step functions when the detectors were rotated in the fields of gamma ray or x-ray photons generated by point sources. The sensors located point sources accurately at intensities as low as 10 photons per cm²-s in the presence of much higher intensities from other sources. Their unique ability is that they can distinguish between photons emitted by a point source that did not interact on their way from the source to the detector from those that did interact. This paper reports on the design and fabrication of a new directional scintillation sensor with a sensitivity 45X greater than previous designs. The results show that the new sensor can be used in gamma and x-ray astronomy.
