ATLAS Detector Commissioning using Offline Software
Table of Contents
1. Introduction
Commissioning brings the ATLAS systems (detectors, TDAQ, HLT) from just installed to operational. It refers mainly to activities at Point 1 and to integration. Offline commissioning deals primarily with the use of offline software during detector commissioning.
Commissioning proceeds in four phases:
- Subsystem standalone commissioning
- DCS: LV, HV, cooling, gas, safety, DB recording and retrieving
- DAQ: pedestal runs, electronic calibration, write and analyze data
- Integrate systems into full detector
- Cosmic rays
- Record data, analyze/understand, distribute data to remote sites
- Single beam data, first collisions
- Similar to cosmic rays, but working with increasingly higher rates.
Offline commissioning tackles the requirements for the ATLAS offline software during all four commissioning phases. The phases will overlap since different systems may be in different phases. Commissioning has started and will last well into 2007.
