The Hi. SPARC 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 Stations in the Netherlands Hi. SPARC Detector 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 Hardware: - 2 plastic scintillators - 2 photo multiplier tubes (-12 V) - 2 ski-boxes - GPS device and antenna - timestamps ~5 ns accurate - Hi. SPARC II control box - USB 2. 0 - Each channel @ 400 MHz - 12 bit ADCs (-2 V < Vin < 0 V) - Buffer for 3 events/channel Typical Hi. SPARC station with 2 detectors. School’s finance: ~US$ 6, 000 Option: 4 detectors → reconstruction of shower direction Data Acquisition Physics Data DAQ Software uses: - NI run-time engine - Python - SQLite - My. SQL Status & Control http: //data. hisparc. nl/ Public Database: - Based on Django web-framework - Administration: station, certificates, contact info - Online histograms, analysis, physics data http: //vpn. hisparc. nl/ Data quality: Status & Control uses: - Open. VPN - Tight. VNC - Nagios - Django weatherstation Hi. SPARC @ http: //github. com/Hi. SPARC/ References [1] Hi. SPARC home page: http: //www. hisparc. nl/ [2] D. Fokkema, “The Hi.
