Teaching and Learningwith Cosmic Rays
•Paradigm: a good way to learn science?
--> participate in data-based science
−ask cosmic ray questions
−marshal a research plan
−engage hardware and technology
−analyze realistic, not simulated data
−share results with collaboration

QuarkNet creates a collaboration of users
Teachers <---> Students
Teachers <---> Mentor Scientists
Detector Schools <---> Non-Detector Schools
World-wide network: Students <--> Students
• Sources of Cosmic Rays– Supernova remnants– Active galaxies (?)– Quasars (?)– Gamma Ray Bursters (?)– Dark Energy (?)
Teaching and Learningwith Cosmic Rays
• Cosmic rays at earth– primaries (protons, nuclei)– secondaries (pions)– decay products (muons, photons, electrons)
1-2 μ per second

Teaching and Learningwith Cosmic Rays
• Wealth of open, cool science questions• ?: WX, lightning, biology, climate,
data bits, solar storms
• CR e-Lab --> not prescriptive, not recipes
• Provide resources and analysis tools
• Trust the teacher to guide research
BIG science: Students copy/reproduce• Auger --> Argentina
http://www.auger.org• MINOS Far Detector --> Soudan Mine, Minnesota
http://farweb.minos-soudan.org/events/• CMS --> LHC, CERN, Switzerland
http://cms.cern.ch/• IceCube --> South Pole
http://icecube.wisc.edu/
--> QuarkNet Cosmic Ray e-Lab Studies:direct analog to detector based particle physics
e-Labs
• Teachers & students– assemble– calibrate– set-up & run

Overview: Cosmic Ray Muon Detector
Kris WhelanLawrence Berkeley National Lab
• The QuarkNet Cosmic Ray Muon Detector (CRMD)– plastic scintillator– homegrown DAQ– GPS timing
Teaching and Learningwith Cosmic Rays
Teaching and Learningwith Cosmic Rays
CRMDTypical QuarkNet Detector Setup1. Counters-scintillators,
photomultiplier tubes (two shown)
2. QuarkNet DAQ board3. 5 VDC adapter4. GPS receiver 5. GPS extension cable6. RS-232 cable (to link
to computer serial port)7. Optional RS-232 to USB adapter
(to link to computer USB port instead of serial port)
8. Lemo or BNC signal cables9. Daisy-chained power cables
Teaching and Learningwith Cosmic Rays
CRMD expectation: --> not “plug&play”--> rather “mold&set”
Direct analog of the big detectors in Tevatron and LHC
• DAQ Hardware measures– light pulse timing– ambient temperature– atmospheric pressure
• Experiments include– Flux studies– Time correlation – Shielding– Particle speed– Particle lifetime– Altitude attenuation

Types of counter configuration1) array --> shower
counters distributed2) stacked --> flux
counters spaced on common center
• Determined by type of CR study• Student defined

NEXT SESSION: Breakout into small teams
--> Assemble Cosmic Ray Muon Detectors4 counters: one team eachDAQ/GPS: one team
Next: Cosmic Ray e-Lab and UPLOAD data

--> Cosmic Ray e-Lab
Lower the threshold to analyzing real data
Teaching and Learningwith Cosmic Rays
But there are more e-Labs on the horizon……
• Ligo -- weeks away• CMS -- months away• Atlas -- year away• Other science with large data sets….
SDSS? Mars Rover? weather? ocean?
e-Labs
Major strength of e-Labs……
• First time: teachers and students --> GRIDLarge cluster of machines at Argonne Nat’l Lab GRID gateway at Univ of Chicago
• e-Labs: same structure & format, “look/feel”
