  The ABALONE Photosensor Technology (U.S. Pat. 9064678) is a modern, scalable
technology specifically invented for cost effective mass production,
robustness, and high performance. We present the performance of advanced fused
silica ABALONE Photosensors, developed specifically for the potential extension
of the Ice Cube neutrino experiment, and stress tested for 120 days. The
resulting performance makes a significant difference: intrinsic gain in the
high 100 million range, total afterpulsing rate of only 0.005 ions per
photoelectron, subnanosecond timing resolution, single photon sensitivity, and
unique radiopurity and UV sensitivity, thanks to the fused silica components,
at no additional cost to the assembly process.
