Description

The Center for Space Research has been operating four neutron monitor (NM) stations since the 1960s and has also developed mini neutron monitors, initially to calibrate the stations. To upgrade the aging electronics in the NMs, a new electronic system has been developed. The aim of the new electronic design is to be modular so that it can be easily adapted to fixed or mobile NMs. The system uses commercial-off-the-shelf components and publicly-available software where possible.The software and hardware designs will be made freely available to the international NM community. The system is also designed to be easy to maintain and calibrate, to be inexpensive, to be shielded against electromagnetic interference and to make the data available on the internet in real-time. The electronic system also features a fast acquisition system for pulse shape recording and microsecond accurate event timestamps. The pulse profiles are used for calibration and integrity testing to ensure long term stability. The accurate timestamps make multiplicity and time-of-arrival studies possible. Some first measurements with the new electronic system are presented and compared to previous systems.
