About the Graphs above:
Top left: Waveforms characteristic of stopping muons have two distinct pulses (one from the muon and one from its decay product).
Top right: Each time a we record a stopping muon, we measure the time between the two pulses and increment this histogram. After enough muons have stopped, it will have an exponential distribution with a decay constant equal to the average muon lifetime, about 2.2 microseconds.
Bottom left: Muons that pass through our detector have give only one pulse. Periodically, we record one of these here. This graph is updated most often of the three.
- To print a graph, use right click then print, or (for Mac) hold down control, click, and select print.
- Clicking on a graph will take you to the homepage of the developers of the graph software.
- If you have trouble, reload the page.(Page auto-reloads every 15 minutes)
- The stopping muon waveforms should update approximately every 3 minutes.
- The passing muon waveforms update approximately every 4 seconds.
- There will be no meaningful fit until >= 50 stopping muons have been recorded.
