The MonRAt Telescope for Atmospheric Fluorescence Radiation
Abstract
The Atmospheric Radiation Monitor (MonRAt) is a compact telescope, being built in Brazil, designed to detect photons generated by ultra-high energy cosmic ray showers in the atmosphere. It is composed by a parabolic mirror focusing light onto a 64-pixels multianodic photomultiplier tube. Ultraviolet-passing filters are positioned in front of the photocathode to select photons within the wavelength range of 300 and 400 nm. The data acquisition system consists of a front-end, a set of pre-amplifiers and FPGA-based boards able to record trigger times and waveforms from each channel. MonRAt is being designed to detect air fluorescence radiation under different atmospheric and geomagnetic conditions. Also planned are Cherenkov radiation measurements as well as atmospheric monitoring in the lidar mode.
