1 T. Jordan, Advisory Board Meeting - November 2002 Advisory Board Meeting T. Jordan, Advisory Board Meeting - November 2002 Data Projects Thomas Jordan FNAL

2 T. Jordan, Advisory Board Meeting - November 2002 Advisory Board Meeting 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.... August, 1998 Wesley Smith, University of Wisconsin, CMS TrDAS:... There should be a trigger dedicated to QuarkNet....

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

4 T. Jordan, Advisory Board Meeting - November 2002 Advisory Board Meeting Run II Website:

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

6 T. Jordan, Advisory Board Meeting - November 2002 Advisory Board Meeting Run II Website: They use three types of data.... Plots from the experimentsExcel spreadsheetsStudent generated plots

7 T. Jordan, Advisory Board Meeting - November 2002 Advisory Board Meeting Run II Website:... and make cuts on b lifetime & W mass, as well as generate di-jet mass plots. 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.

8 T. Jordan, Advisory Board Meeting - November 2002 Advisory Board Meeting Online Cosmic Ray Detector:

9 T. 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). Online Cosmic Ray Detector:

At 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. Advisory Board Meeting Online Cosmic Ray Detector:

11 T. Jordan, Advisory Board Meeting - November 2002 Advisory Board Meeting Online Cosmic Ray Detector: 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.

12 T. Jordan, Advisory Board Meeting - November 2002 Advisory Board Meeting 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.... August, 1998

13 T. Jordan, Advisory Board Meeting - November 2002 Advisory Board Meeting Manipulative, Interactive and Physical Materials: We have ~50 of these cosmic ray detectors in QuarkNet classrooms and will soon have >100.

14 T. 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 - UIC node has a detector Unfortunately, we have no hard data to answer the question, only anecdotes.

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