Yes, you can!
You can now try our Masterclass on your own, if you wish. Are you ready to accept the challenge?
Here is what you need to do:
- Learn enough about KM3NeT: we recommend you first check this introduction to KM3NeT
- Familiriase yourself with how KM3NeT works by re-ordering our event displays! Please find the instructions for event display exercise here and then get the set of events from here
- Get what you need for the next steps of the exercise by downloading the calibration.csv file (important: the format of the calibration file has to respect the rules explained below)
- Ready for more? Help us please to recalibrate some miscalibrated detection units! The instructions for the calibration exercise are here. When you are ready, open the link you will find in the last slide
- The final goal: look for neutrinos from selected potential sources in the sky! The instructions for the sky map exercise are here. When you are ready, open the link you will find in the last slide
Tips for getting the best out of this experience:
- For the event display exercise, look at the movies from all allowed angles to identify the detection units collecting signals, then check the plots
- For the calibration and sky map exercises, make sure the .csv file you use is in the correct format: starting from line 2, you need to have two numbers separated by a comma: a number identifying the detection unit (ranging from 1 to 15) and the offset you want to apply (given in nanoseconds, with three decimal digits). Important: the offset is added to the data; therefore, if you want to shift the values to the left in a plot, you need to specify a negative offset
- Don’t be surprised if a correction of the calibration of one detection unit may change the calibration of the other ones! Due to how the process works, the plots of all detection units are correlated: consequently, correcting one detection unit at a time is not the best strategy… You should always try to improve them all at the same time. And also: it is pretty unlikely you can envision the ultimate offsets in just one try! You should better prepare to perform the exercise recursively (usually, 3-4 iterations should be enough)
- The calibration and sky map are indeed correlated (no surprise, as calibration affects the response of the detector): you might want to check how the improvements of the calibration affect the outcome of the source search?
- You might want to use this suggested sheet to record your results
And finally: no exercise is ever complete if you don’t have a way to check your outcome: send us your results at km3net-oc@km3net.de and we will be happy to comment on them as well as on the feedback from your experience that you may want to share! We are also here to support you with the help you may need while doing the exercises or for any additional information you might want to get!
