Description
Re-configurable Open Architecture Computing Hardware (ROACH) developed by Collaboration for Astronomy Signal Processing and Electronics Research (CASPER) is a single processor, FPGA based board with the ability to accept a number of different add - on electronics for signal processing. Project 8 is a novel experiment making use of cyclotron radiation emission spectroscopy (CRES) technique to measure the energy of $^{83m}Kr$ beta decay electrons trapped in a magnetic field, with the aim of improving this technique to directly probe the neutrino mass by locating the cut off energy of the beta spectrum. The most important signal is the RF cyclotron radiation emitted from magnetically trapped beta decay electrons. The pre-requisite of Project 8 is to be able to resolve the electron energy to a high degree which is only possible with precision digitization and analysis of the RF cyclotron radiation. The system is programmed using XILINX library and controlled online by the open source custom made MANTIS software package. We will present an electronics application build from ROACH with the ability to digitize and process GHz signals to 12 bit precision with the aim of implementing level 1 online analysis on the ROACH board itself.
