NSF ESIE Proposal:

. . . To facilitate classroom change, we will provide access to a wide variety of online instructional resources including raw datasets and primary sources, and manipulative,interactive and physical materials. . . .

. . . There should be a trigger dedicated to QuarkNet. . . .

. . . Raw Datasets . . .

We feel that this will be iterative and have made two first-order attempts to prepare for “live” data:

• Run II website

• Online cosmic ray detector

Run II Website:

Run II Website:

Students are “particle detectives” searching for Higgs in the: channel.

IF YOU HAVE NEW INFORMATION CONCERNING THIS PARTICLE, PLEASE CONTACT THE NEAREST ACCELERATOR LABORATORY OR PHYSICS DEPARTMENT.

Thanks to John Conway (Rutgers, CDF Higgs group) for the Monte Carlo Higgs and background data.

Also to William Wester (FNAL, CDF) for the data for Z and W reconstruction.

Online Cosmic Ray Detector:

T. Jordan, Advisory Board Meeting - November 2002T. Jordan, Advisory Board Meeting - November 2002

Advisory Board Meeting

An array of three scintillating plastic counters

A dedicated DAQ reads out the PMTs, discriminates the signals and performs all of the trigger logic.

Two triggers: >1-fold coincidence, decay candidates

A serial connection ports trigger data to an Apple machine in my office which cleans and writes the data to AFS space (QNet webserver).

Data are written in 24-hour blocks—each block starts at noon Greenwich time, the beginning of a new Julian day.

At 12.00 GMT, my computer:

• Stops the current data run.

• Starts a new data run.

• Cleans up the data from the previous day:

• Makes a backup of the original, converts from hex to decimal, and writes events to file: one for

each trigger.

Students can use the data to study flux as well as events that satisfy the decay trigger.

The plot shows decay candidates from the middle counter during the first several weeks of running.

Manipulative, Interactive and Physical Materials:We have ~50 of these cosmic ray detectors in QuarkNet classrooms and will soon have >100.

T. Jordan, Advisory Board Meeting - November 2002T. Jordan, Advisory Board Meeting - November 2002

Advisory Board Meeting

Who Uses These Materials?

• Students & Teachers in QuarkNet classrooms - Jason Fox

• Teachers - Bill Lamb and Jeff Rylander

• University Faculty - Mike Strauss and Darin Acosta

• QuarkNet Nodes - Everyone @ UIC node has a detector

Unfortunately, we have no hard data to answer the question, only anecdotes.

Next Steps:

• Set up and test pilots, make edits, broaden audience.

• Finish current batch of detectors.

• Investigate the value-added of the classroom detectors.

• If that investigation is favorable, find a way to make more.
