Use of Quarknet equipment and resources
1. Address measurement uncertainties through setup and data collection from a 24 hour run.
Time of flight analysis from 24 hour run data. Using distance, estimate average speed of particles.
Using known rest half-life, estimate depth in earth at which muon signal should disappear.
“Our mission is to create opportunities for teachers and students to explore the nature of scientific research. Using cosmic ray muon detectors, participants design and perform experiments to analyze data employing the cosmic ray e-lab.”
a. Configure a cosmic ray detector appropriately for acquisition of data for calibration and analysis of measurements.
How to Run EQUIP from Raspberry Pi
In Command Prompt type: sudo apt-get install librxtx-java
In web browser, go to cosmic ray elab. in Library, Resources, select EQUIP java interface and download EQUIP_18JUL2014.
You can put this anywhere you want but I would suggest on the desktop. (The rest of this walkthrough is assuming the Desktop.)
To run EQUIP:
Open the terminal so you have a command prompt.
Make sure your directory is in the Equip Folder:
Make a copy of the following script and paste into the command line:
java -Djava.library.path=/usr/lib/jni -cp /usr/share/java/RXTXcomm.jar -jar EQUIP_18JUL2014.jar
Create and save your file name before you find the port.
in log file:
select Choose File and assign the in the EQUIP folder on your desktop or on a USB Drive
select: media, pi,(USB Name), EQUIPDATA (if you want it to be in a folder with this name)
Create a new file name: I suggest something like:
Note: Stack_46cm indicates that I have a stacked geometry with a 46cm difference between counters 1 - 4.
You should have something like this to note your geometry to make it easier to identify your data.
Save (you can check to see that your file got created by looking in the data folder you want it to go in)
Find your DAQ in Choose Port. You will know you found it when the screen fills with your information. Wait to make sure you have enough satellites, make sure you have your settings the way you want and enable counts.
