Cosmic Rays e-Lab
Cosmic Ray hardware and DAQ
Cosmic Ray data
Several data formats and file types are used in the Cosmic Ray e-Lab.
Cosmic ray data is stored on i2u2-data
. In addition to an assortment of
files, this directory contains subdirectories for each DAQ. These directories store data for that DAQ in sets of up to three files of the form
-rw-r--r-- 1 quarkcat 51 468 Nov 28 2014 6333.2012.1225.2.bless
-rw-r--r-- 1 quarkcat 51 3.7M Jun 13 2015 6333.2012.1225.2.thresh
-rw-r--r-- 1 quarkcat 51 3.0M Jul 25 2013 6333.2012.1226.2
file will exist only if the data has been blessed) plus one
geometry file for that DAQ.
Discussion and Documentation
Atmospheric pressure correction
Cosmic Ray flux varies with atmospheric pressure. If we can correlate trigger rates with ambient pressure, we can normalize for the effect to search for seasonal variations in flux over long time scales and over large areas.
This is a working section for this project, started in Mar2017.
