Cosmic Ray Detector Experiments LBNL 2017

Purpose –This experiment gave hands-on experience collecting & interpreting data from muon detectors. These detectors were supplied by Howard Matis of LBL. Students had had no previous experience with the detectors.
Methods –Before working with the detectors, students viewed a video about special relativity & muon decay on their own. The two hour formal session started with a 30 min power point presentation on what cosmic rays are and how we detect them. Then, students were shown a high voltage gas detector. Followed by a discussion, students were trained on how to use the detectors. There were 9 groups comprised of 4 students and 1 teacher. Each group had its own detector. Each group designed a brief experiment. These experiments ranged from tilting the detectors to get a different count to shielding experiments using different floors in a building. The experiment that most groups did was going to different levels of the building to see if the counts change due to shielding.
Results - Each group recorded their data and presented their findings informally. Because of time constraints, there was no formally written data shared with the entire group. Some groups did mention specific numbers of muon counts. There was a discussion covering the causes of the difference in counts. Their counts in the upper floors of the building were more than the lower floors.
There was also a discussion on why the two detectors had different counts which lead to an explanation which covered the role voltage plays in the sensitivity of the paddles. Too high of a voltage gives a runaway count, too low of a voltage gives no count.
Meaning & future investigations - Cosmic rays have played a large role in the development of Particle Physics. The muon as well as antimatter were first detected by cosmic ray investigations. Students had also had a presentation on Cosmic Rays & the ICE Cube experiment. This activity gave the students a first-hand experience in understanding & working with particles and helped them make connections with larger research experiments. Further investigations could include continuing to study the different shielding materials, different elevations of detection, & the effects of magnetic fields on the detector as well as the earth’s magnetic field.

Purpose –The purpose of this experiment was for students to have hands on experience collecting & interpreting data from muon detectors. Students have had no previous experience using detectors. These detectors were supplied by Howard Matis of LBL.
Methods – The experiment was broken up between two days. There were 10 teams, each with 4 students, 1 teacher & 1 detector. The first day, students learned how to use the detectors & were asked to design a brief experiment. These experiments ranged from tilting the detectors to get a different count to shielding experiments using different floors in a building. One interesting experiment that two groups conducted at different times were to place a bag of ice on the detectors. Both groups got an increase in muon counts.
Results - The data was recorded to various degrees, by each group. Because of time constraints, there was no formally written data shared with the entire group. There was a debriefing with a discussion of the results in general terms. Some groups did mention specific numbers of muon counts. Each group that carried out the angle experiment had results that confirmed that you would get less counts if the paddles were vertical. There was a discussion covering the causes of the difference in counts depending upon the orientation in a given detector. Each group saw there was a much higher count when the paddles were orientated horizontally as opposed to vertically. This difference provided confidence that muons were detected, not just electrical noise.
There was also a discussion on why the two detectors had different counts which lead to an explanation which covered the role voltage plays in the sensitivity of the paddles. Too high of a voltage gives a runaway count, too low of a voltage gives no count.
One group tried to use the entire magnetic field of the earth, using the right hand rule to see if there were more counts facing west compared to east. General consensus of that group was that they count more counts when facing west. But they were trying to combine this with a tilting experiment so there were too many variables to have a valid result.
The surprising result of the ice on the detector may have been due to the whole detector’s resistance was lowered allowing for a larger count. Another possible explanation was that muons were hitting the ice which created a shower of electrons into the paddles.
Meaning & future investigations - Cosmic rays have played a large role in the development of Particle Physics. The muon as well as antimatter were first detected by cosmic ray investigations.
This activity gave the students a first-hand experience in understanding & working with particles. Working with detectors also helped the students understand the collection of subatomic particles importance on much larger scales such as in SNO+ experiment.
Further investigations could include continuing to study the different shielding materials, different elevations of detection, & the effects of magnetic fields on the detector as well as the earth’s magnetic field.
Physics in and Through Cosmology 2016

Lawrence Berkeley National Laboratory
Annual Report 2016
July 6, 2016
Mentors: Tony Spadafora, Alex Kim, & Alessandra Ciocio
Workshop Coordinator: Laurie Kerrigan
Co- Organizer: Ken Cecire (QuarkNet)
The LBNL Physics Division hosted its tenth “Physics in and Through Cosmology” workshop for QuarkNet Leadership teachers and high school students. The five-day workshop from June 20 to June 24, 2016 was held at the Lawrence Berkeley National Lab. Thirteen science teachers participated. Five of the teachers have been active members of QuarkNet for five or more years. Six new teachers joined the group this year. There were 40 students with approximately equal number of boys and girls. The teachers & students represented public and private high schools in the greater San Francisco Bay Area.
The first day focused on getting all participants familiar with concepts & terms in particle physics & cosmology. This was accomplished through “mini” lectures given by returning QuarkNet teachers & Blake Sherwin, an LBNL researcher. The LBNL 88” cyclotron was also toured.
The other days consisted of hands-on warm-up activities, a morning scientist talk and an afternoon talk. Between talks, groups worked on hands-on experiments (e.g. QuarkNet activities lead by Ken Cecire using data from ATLAS). Participants also discussed the lectures. They had a virtual tour of the ATLAS Control Room at the CERN Large Hadron Collider (with more Q&A about Supersymmetry), and viewed Alessandra Ciocio’s ATLAS SCT Cable Installation and Detector Connection video. There were also tours of the ALS (Advanced Light Source) and Molecular Foundry research facilities at LBNL.
Groups designed & carried out experiments with Cosmic Ray Detectors. Each group consisted of four students and one teacher.
Teachers meet with Ken Cecire over lunch on the second day to discuss QuarkNet.
Formal presentations included:
Standard Model and Higgs - Robert Clarke
Beyond the Standard Model, Exotics and Searches - Jennet Dickinson
ATLAS masterclass measurement - Ken Cecire
Surprise drop in by Saul Perlmutter
Supernova - Clare Saunders
Dark Matter - Peter Sorensen
CMB - Darcy Barron
LIGO gravitational waves - Brett Noah Shapiro
Rocket Science - George Smoot
Cosmic Rays - Spencer Klein
Panel Discussion - Darcy Barron, Alex Kim, Spencer Klein, Brett Noah Shapiro
On the last day students completed a self- evaluation of how much they learned about science concepts during the workshop. They used a scale of 1 (nothing) to 5 (a lot).
The overall average for all of the students for all of the concepts was 4.0 with a standard deviation of 0.54
The two concepts with the highest overall evaluation of 4.54 were:
According to the Big Bang Theory the Universe has expanded from initial conditions of
being very small, hot and dense.
The Cosmic Microwave background is the baby picture of the Universe when matter &
energy decoupled
Others that received high marks were:
The Universe is approximately 5% atomic matter, 20% dark matter, and 75% dark energy.
4.49
Cosmic rays interact with material on Earth. 4.49
Space itself is expanding. 4.46
Supernovae are the explosions of dying stars, and certain types can serve as a standard
candle. 4.43
Know that when an observation does not agree with an accepted scientific theory, the
observation is sometimes mistaken or fraudulent (e.g., the Piltdown Man fossil or
unidentified flying objects) and that the theory is sometimes wrong (e.g., the Ptolemaic
model of the movement of the Sun, Moon, and planets). 4.43
Recognize the issues of statistical variability and the need for controlled tests. 4.32
Analyze situations and solve problems that require combining and applying concepts
from more than one area of science. 4.32
Quarks have color & flavor & make up protons & neutrons. 4.24
Some comments by the students and teachers include:
Honestly, I learned more in this 1-week period than I did in most full-year science
classes I’ve taken. (student)
I liked seeing all the science labs, and seeing actual scientists doing research. I learned
much about outer space and molecular physics, which I enjoyed because high school
barely covers these topics. (student)
I learned a great deal about current cosmological & particle physics research. (teacher)
It piqued my interest into particle physics. (student)
This definitely opened my mind more about the world around. Before I was taught that
atoms were essentially the smallest unit of matter or whatever and that they couldn’t
be broken down, but, now I know that there’s a whole set of new particles! (student)
I loved learning from experts and being able to ask the difficult questions that my high
school teachers wouldn’t know. (student)
I learned a lot about space from the very large scale universe physics to particle physics,
and the experience was definitely useful in deciding what I would like to study in
college. (student)
I learned more in this one week than I usually learn in a month. (student)

The LBNL Physics Division hosted its ninth “Physics In and Through Cosmology” workshop for QuarkNet Leadership teachers and high school students. The five day workshop from June 22 to June 26 was held at the Lawrence Berkeley Lab. Ten science teachers participated. Five of the teachers have been active members of QuarkNet for five or more years. Three new teachers joined the group this year. The QuarkNet Teachers and 42 students represented public and private high schools in the greater San Francisco Bay Area.
The first day focused on getting all participants familiar with concepts & terms in particle physics & cosmology. This was accomplished through “mini” lectures given by returning QuarkNet teachers & two LBL researchers: Alex Kim and Danny Mittelberger.
The daily format consisted of a hands-on warm-up activity, a morning scientist talk and an afternoon talk. Between talks, groups worked on hands-on experiments (e.g. QuarkNet acitivty lead by Ken Cecire using data from ATLAS), discussed the lecture, and toured the ALS (Advanced Light Source) and Molecular Foundry research facilities. Groups also designed & carried out experiments with Cosmic Ray Detectors. Each group consisted of five to six students and one teacher.
Teachers also meet with Ken Cecire over lunch on the second day to discuss QuarkNet.
