Undergraduate Research in Particle Astrophysics
CUNY Cosmic Ray Detector Array for Undergraduate Research in Engineering and Computational Physics
The Queensborough Community College physics department is building a cosmic ray detector array for undergraduate student research. College students and high school physics teachers are involved in building the array which includes detectors at different college campuses interconnected over the Internet. In building and operating detectors students and teachers gain valuable training in engineering science, electronics, computer programming, data analysis, and project management. A learning community has been established where students are engaged in high impact practices and active learning. Science goals include measuring the rate and directionality of 10 m to 10 km wide cosmic ray muon showers, and correlations with atmospheric variables and solar activity.
Opportunities for Students
If you plan to work with electronics, mechanical equipment, or computers in engineering or science there is nothing better than to design and build things now as hands-on hard work opens up many doors for your future. Students accepted into the program can register for Physics Research Projects PH900 (90 lab hours, 2 credits) and/or Scientific use of Computers PH303 (2 credits):
- Design and build scientific equipment
- Build beginner or advanced electronic circuits
- Write software in Python or C++ for systems control and data acquisition
- Build particle physics detectors: design framing, machine parts, water jet applications
- Measure cosmic ray particles from outer space
- Present research results at conferences
- Apply for summer research opportunities at QCC and Brookhaven National Lab
- Publish papers
