Introduction to Quark Net Lab Activities SU Summer

Introduction to Quark. Net Lab Activities @SU Summer 2012 R. Mountain, M. Soderberg, S. Blusk with Erika Cowan, Anna Fadeeva, Dylan Hsu, Emily Kraus

Overview Purpose of these lab activities • Reinforce material to be presented in lectures • Give you some idea about how experiments are done in High Energy Physics Provide you with some take-away • Ideas and concepts from High Energy Physics for your use in class lectures • Hardware for classroom or lab activities of your own R. Mountain, Syracuse University SU Quark. Net Program, Summer 2012 2

Lab Activities 1. 2. 3. 4. 5. Muon Lifetime Gamma Spectroscopy Wire Chamber Wires & Resonance Behavior Electronics I: Op Amps & Si Dets Electronics II: ADCs & DAQ Plus: Cosmic Ray Telescope (Mini-Workshop) R. Mountain, Syracuse University SU Quark. Net Program, Summer 2012 3

Organization Groups • Four groups of 2– 3 persons each, five lab activities, assignments TBD • Round-robin, two days per activity, ~1½– 2 hr per session per day (AM/PM sessions) • Assistance from students who’ve done the labs: Erika, Anna, Dylan, Emily Materials & Procedure • Logbooks for everyone! • Write-ups for each lab: introductory material and specific activities (can do more) • Webpage with online references, help, background tutorials, etc. (permanent feature) linked from main page * Mini-Workshop • Separate, details will come during miniworkshop, 7/9 -11 * http: //www. phy. syr. edu/hep/HEPOutreach/Quark.

Safety Issues Be careful, be aware you are in a lab environment Dealing with: • High Voltage • Radioactive Sources • Sensitive Detectors Stay safe, just follow instructions Any questions, just ask

Helpful Suggestions (Stop me if you’ve said this before…) Read lab material • Ahead of time (…if possible) • Some reference material and links on the activities webpage will be helpful Use your logbook • For info, questions, data, etc. The point is to learn, so: • • Ask questions (Pauli) Try to figure things out Find help, if you need help Don’t get stuck! This will be fun… R. Mountain, Syracuse University SU Quark. Net Program, Summer 2012 12
