Data Production at ICARUS

ICARUS is a liquid argon time projection chamber detector which serves as the far detector for the Short Baseline Neutrino (SBN) program at the Fermilab campus. In a normal year of data-taking, ICARUS runs at about 0.8 Hz when running with beam and at about 0.5 Hz for off-beam events. The effective annual rate is 0.725 Hz, producing about 23 million raw data events. In terms of data space occupancy, given an event size of about 162 MB/event, the data can run upward of about 4 PB in disk space. In its first run, ICARUS produced around 0.5 PB worth of data in the span of about a month and is expected to take more than 3 PB worth of data in three months for its second run. All these data need to be processed via the decoding and filtering stages to ensure data quality and to pass through event reconstruction algorithms before being used for physics analysis. This talk will discuss all the steps taken at ICARUS to turn raw data into analysis worthy data.
