Teaching and Learningwith Cosmic Rays

• QuarkNet Overview

• QuarkNet Cosmic Ray DetectorAssemble CRMD hardware and take data.

• Cosmic Ray e-Lab ExplorationUpload and analyze data.


Workshop Objectives:

• Assemble CRMD: plateau, geometry, data-take.

• Record progress: LogBook.

• Design e-Lab investigation: data, tools, plots.

• Write poster, present results.

Time Difference (ns)

Difference in Absolute Time

• 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?

--> 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

• Provides resources and analysis tools

• Trusts the teacher to guide research

BIG science: Students copy/reproduce• Auger --> Argentina

Teachers & students:– Assemble.– Calibrate.– Set-up and run.




Overview: Cosmic Ray Muon Detector


The QuarkNet 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


CRMD Expectation: --> Not “plug & play”--> Rather “mold & set”

Direct analog of the big Tevatron & LHC detectors

CDF DZero ATLAS CMS

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 distributed2) Stacked --> flux

Counters spaced on common center

• Determined by type of study• Student defined


NEXT SESSION: Break out into small teams.

--> Assemble cosmic ray muon detectors.4 counters: one team eachDAQ/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.


There are more e-Labs on the horizon . . .

• LIGO - weeks away• CMS - months away• ATLAS - a year away• Other science with large data sets . . .

SDSS? Mars Rover? weather? ocean?

•Learning Objectives: (What will you expect students to know and be able to do as a result of conducting the e-Lab).

•Standards: (Whichever ones you are being held responsible for) being addressed.

•Steps: In the plan (e.g., 1. assess prior knowledge by?; 2. provide background information by?; 3.?4.?5. have students complete the poster).
