• Cosmic Rays– Sources– Composition, energy spectrum– Detection– Current experiments

• The QuarkNet Classroom Detector– Hardware overview– Classroom use– Experiments, measurements

• Data Analysis– Upload, analyze data & save data products– Share results– Enter logbook notes



•Paradigm: a good way to learn science?

May 2008•419 teachers accounts

•835 student research groups

•over 65,000 analyses run

•314 detectors in high schools

•15275 data files

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 (?)


• Cosmic rays at earth– primaries (protons, nuclei)– secondaries (pions)– decay products (muons, photons, electrons)

1-2 per second



Run: CR shower video if fast connectionhttp://astro.uchicago.edu/cosmus/projects/aires/protonshoweroverchicago.mpeg


•Wealth of open science questions•Students participate in active, big science•QuarkNet --> not prescriptive, not recipes•Provide resources and analysis tools•Trust the teacher to guide research

BIG science:• Auger -->

--> QuarkNet Cosmic Studies:direct analog to detector based particle physics

e-Labs

• Teachers & students– assemble– calibrate– set-up & run


Overview: Cosmic Ray Muon Detector


• The QuarkNet Classroom Detector Cosmic Ray Muon Detector (CRMD)– plastic scintillator– homegrown DAQ– GPS timing



CRMD

Typical 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

• 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 e-Lab and UPLOAD data

• There has to be an easier way . . .

--> Cosmic e-Lab

Lower the threshold to analyzing real data


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”
