Death by commissioning

Commissioning Experience with Caribu

The Californium Rare Ion Breeder Upgrade (CARIBU) of the ATLAS superconducting linac facility aims at providing low-energy and reaccelerated neutron-rich radioactive beams to address key nuclear physics and astrophysics questions. These beams are obtained from fission fragments of a Cf-252 source, thermalized and collected into a low-energy particle beam by a helium gas catcher, mass analyzed b...

The Verification of iPlan Commissioning by Radiochromic EBT2 Films

Purpose: To evaluate the measured dose distributions using radiochromic EBT2 films for small fields in iPlan (BrainLab) commissioning. Methods: Radiochromic EBT2 films were irradiated with 6 MV photons on a Varian Trilogy linac using polystyrene phantoms. The measurements included dose profiles and depth doses for field sizes of 1 × 1, 2 × 2, 3 × 3, 4 × 4, and 10 × 10 cm etc. The dose profile m...

Commissioning ATLAS Trigger

The Large Hadron Collider (LHC) at CERN, Geneva, is now starting operation. It will ultimately provide protonproton collisions at a centre-of-mass energy of 14 TeV, a design luminosity of 10 cm−2 s−1 and a bunch-crossing rate of 40 MHz. The ATLAS collaboration has built a general purpose experiment for the LHC which is described in [1][2]. The trigger and data acquisition (T/DAQ) system must wo...
