International Masterclasses

with ATLAS data

Uta Bilow, TU Dresden

ATLAS O&E 11.02.2014, CERN

ATLAS O&E 2/2014 Uta Bilow, TU Dresden 2

Concept of IMC• High school students (15 – 19) are

„scientists for one day“

• Get invited to a research institute or

university

• Introductory talks (standard model,

detectors, accelerators)

• 2 h measurement with LHC data

• International video conference (3 – 5

inst. + CERN/Fermilab)

Plans and next steps1. MICAB initiative (Ken Cecire) Masterclass Institutes Collaborating in the Americas and beyond

• Spreading Masterclasses to US, Latin America, Asia

• Sponsored by ATLAS, CMS, QuarkNet, and the University of Notre Dame

2. Presentations/MCs on Conferences

• ICHEP Valencia 7/2014

3. Press

• CERN press office: press release

• CERN Courier (June?): "Feature of the Month" article on ‚Masterclasses in the LHC era'

4. Expansion of International Masterclasses

• TOTEM well advanced with a measurement, pilot test soon

• ICE-Cube: under development
