•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

• 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

Overview: Cosmic Ray Muon Detector
Bob Peterson
Fermi National Accelerator Lab
Teaching and Learning
with Cosmic Rays
• The QuarkNet Cosmic Ray Muon Detector
(CRMD)
– plastic scintillator
– homegrown DAQ
– GPS timing
Teaching and Learning
with Cosmic Rays
CRMD
Typical QuarkNet Detector Setup
1.
Counters-scintillators,
photomultiplier tubes
(two shown)
2. QuarkNet DAQ board
3. 5 VDC adapter
4. GPS receiver
5. GPS extension cable
6. 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 cables
9. Daisy-chained power cables
Teaching and Learning
with 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 configuration
1) array --> shower
counters distributed
2) stacked --> flux
counters spaced on common center
• Determined by type of CR study
• Student defined
Teaching and Learning

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

• There has to be an easier way . . .
--> Cosmic Ray e-Lab
Lower the threshold to analyzing
real data
e-Labs
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 --> GRID
Large cluster of machines at Argonne Nat’l Lab
GRID gateway at Univ of Chicago
• e-Labs: same structure & format, “look/feel”
