  1. The HiSPARC Control System High School Project on Astrophysics Research with Cosmics B. van Eijk, D. Fokkema, R. Hart, A. de Laat, Nikhef, Amsterdam, Netherlands ICALEPCS 2013, San Francisco, USA High-Energy Cosmic Ray Air Shower Research & Outreach • Research & Outreach: • Detection of air showers on a large surface • 2013: more than 100 stations in the Netherlands • Also stations in Denmark and England • Recording atmospheric conditions: • weather, lightning • Students build the detectors and analyse the data • Educational materials for high-school teachers and junior and senior students • Organization: • Joint effort science institutes • Coordination @ Nikhef Amsterdam: • data collection and processing • organization, management, development Stations in the Netherlands HiSPARC Detector • Hardware: • 2 plastic scintillators • 2 photo multiplier tubes (-12 V) • 2 ski-boxes • GPS device and antenna • timestamps ~5 ns accurate • HiSPARC II control box • USB 2.0 • Each channel @ 400 MHz • 12 bit ADCs (-2V < Vin < 0V) • Buffer for 3 events/channel Typical HiSPARC station with 2 detectors. School’s finance: ~US$ 6,000 Option: 4 detectors → reconstruction of shower direction Data Acquisition Physics Data http://data.hisparc.nl/ DAQ Software uses: • NI run-time engine • Python • SQLite • MySQL Public Database: - Based on Django web-framework - Administration: station, certificates, contact info - Online histograms, analysis, physics data Status & Control http://vpn.hisparc.nl/ Data quality: Status & Control uses: • OpenVPN • TightVNC • Nagios • Django weatherstation References HiSPARC @ [1] HiSPARC home page: http://www.hisparc.nl/ [2] D.
