Introduction to QuarkNet Lab Activities
@SUSummer 2012
R. Mountain, M. Soderberg, S. Bluskwith
Erika Cowan, Anna Fadeeva, Dylan Hsu, Emily Kraus
SU QuarkNet Program, Summer 2012 2
OverviewPurpose 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

OrganizationGroups• 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, EmilyMaterials & 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

1. Muon LifetimeMotivation & 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

2. Gamma SpectroscopyMotivation & 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)

3. Wire Chamber Wire & Resonance
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

4. Electronics I: Op Amps + Si DetMotivation & 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

5. Electronics II: ADCs + DAQ
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)

Cosmic Ray TelescopeMotivation & 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
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
Safety Issues

(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…R. Mountain, Syracuse University
