  1. Introductionto QuarkNet Lab Activities@SUSummer 2012 R. Mountain, M. Soderberg, S. Blusk with Erika Cowan, Anna Fadeeva, Dylan Hsu, Emily Kraus

  2. 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 SU QuarkNet Program, Summer 2012

  3. Lab Activities • 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) SU QuarkNet Program, Summer 2012

  4. 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 mini-workshop, 7/9-11 * http://www.phy.syr.edu/hep/HEPOutreach/QuarkNet/ SU QuarkNet Program, Summer 2012

  5. 1. Muon Lifetime Emily • Motivation & Goals • Learn about cosmic rays • Hands-on experience with subatomic particles • Lifetime msrmt • Statistics • Setup • Mini version of real high energy physics experiment • Activities • Set up experiment 1st day • Take data overnight • Analyze 2nd day • Take-Away • Physics background and concepts

  6. 2. Gamma Spectroscopy Erika • Motivation & Goals • Learn about radioactivity, radioactive decays • Radiation sources • Energy spectra • PMTs, Scintillators • Setup • Multi-Channel Analyzer • PMTs, Scintillators • Activities • Gamma spectra from several sources and background • Study PMT behavior • Energy calibration • Take-Away • Physics concepts (nuke)

  7. 3. Wire Chamber Wire & Resonance Emily and… • Motivation & Goals • Study resonance behavior • Role of resonance widespread, important application here in detector construction • Setup • Tensioned wire, magnets, frequency generator • Activities • Observe, measure resonant frequencies as function of tension, length, applied magnetic field, etc. • Plus: fun with strobe light • Take-Away • Lots of wire available to take • Simple setup, may already have all components at your home institution

  8. 4. Electronics I: Op Amps + Si Det Dylan • Motivation & Goals • Learn about detector readout chain in HEP (pt.1) • Detector • Amplifier • Shaping • Setup • Solderless breadboard • Electronic components • Oscilloscope • Silicon photodiode • Activities • Learn how amplifiers work • Learn limits in amplitude and frequency • Learn how silicon detectors work • Take-Away • Review of circuits • Oscilloscope operation • Electronics concepts

  9. 5. Electronics II: ADCs + DAQ Anna • Motivation & Goals • Learn about detector readout chain in HEP (pt.2) • Data conversion (and digitization) • Data acquisition • Data manipulation and generally, dealing w data • Setup • TNG3B ADC • Sensors • Computer readout software • Activities • Learn about ADCs, and their properties in amplitude and frequency • Learn how to interface ADC and sensors with computer • Take-Away • Hardware: TNG3B ADC unit, cables, sensors of your choice • Software: NT (NeatTools) interface package, with interactive control and digital logic and I/O (open ended programming component)

  10. Cosmic Ray Telescope • Motivation & Goals • Return to cosmic rays • Several measurements can be made: flux, directionality, lifetime • Setup • PMTs • Scintillators • HV • GPS • Activities • Construct the telescope • Details to be discussed in detail during mini-workshop • Take-Away • Two full telescopes, to share among you • Software for acquiring and analyzing data • Sharing with other stations, at different locations and elevations nationwide

  11. 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

  12. 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. 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… SU QuarkNet Program, Summer 2012
