Abstract

The Antarctic Ross Ice-Shelf ANtenna Neutrino Array (ARIANNA) is a group of semi-autonomous stations designed to detect ultra-high energy (UHE) neutrino particles via radio frequency (RF) pulses. Each ARIANNA station utilizes a field programmable gate array (FPGA) as a means to define a digital logic trigger on an incoming RF signal. The winds and man-made activities in Antarctica affect the trigger rate of ARIANNA stations by creating false positives that uses system memory resources that could be used for UHE neutrino data. Currently, ARIANNA stations are manually set to accept a certain range of RF pulses, limiting false positive recording. The automation of this procedure would maximize the efficiency of system memory resources allocated to UHE neutrino detection, rather than false positive data. We have designed a component, currently dubbed the multi-mode frequency counter (MMFC), which calculates the RF pulse detected by an ARIANNA station with the purpose of furthering the automation of the ARIANNA station. The MMFC was tested using a multi-domain oscilloscope (MDO). The MMFC currently measures 100 Hz to 25 MHz using 16 to 32 bit counter. The algorithm and the performance and design of MMFC will be presented.
