The purpose of this study is to describe the comprehensive commissioning process and initial clinical experience of the Mevion S250 proton therapy system, a gantry-mounted, single-room proton therapy platform clinically implemented in the S. Lee Kling Proton Therapy Center at Barnes-Jewish Hospital in St. Louis, MO, USA. The Mevion S250 system integrates a compact synchrocyclotron with a C-inne...

For the heavy ion programme of the LHC a new ECRIS type heavy ion source had to be designed and built for Linac3 to fullfill the intensity requirements. Experience acquired during the installation and commissioning of the source and during operation for the LEIR ring commissioning will be presented. The performance of the source and its reliability are evaluated. Further requirements for high r...

The ATLAS detector is one of the experiments at the LHC that will detect high-energy proton collisions at 14 TeV. The commissioning of the detector has started already in 2005 in parallel to the detector installation and is still in progress. The data taken so far corresponds to noise runs, cosmic muon events and beam background events from single beam in September 2008. We present the current ...

The ALICE experiment is designed to study strongly interacting nuclear matter which will be produced in heavy ion collisions at the Large Hadron Collider (LHC). The muon spectrometer of the ALICE experiment is equipped with a trigger system based on resistive plate chambers. A commissioning phase was started in 2008 with the detection of cosmic rays and induced particles of the first beam injec...

The paper presents a deterministic method of estimating the transient inductance and rotor resistance of an induction machine for field commissioning purposes. The parameter values obtained by the method are compared with those for a transient method of commissioning. Skin effects inherent with the transient test are documented. Experimental results for a wide range of machine sizes are include...

Commissioning of KEKB started at the end of the last year. In the early stages of the commissioning, we observed transverse instabilities in both rings and started tuning of the bunch feedback systems. Even though the tuning is now at the initial stage, the feedback systems are contributing to an increase of the maximum storable currents in the KEKB rings. Feedback-related systems, tune meters ...

The ALBA Booster is a synchrotron designed to accelerate electron beams from 100 MeV to 3GeV in a 3Hz cycle. The maximum pulse coming from the ALBA Linac provides 5 mA in the Booster. In order to check all the Booster sub-systems, a Booster pre-commissioning took place during two weeks in January 2010. This paper presents the Diagnostics elements installed in the ALBA Booster and our experience...

A case of a successful induction of lactation in a commissioning mother of a surrogate pregnancy is reported. Induction of lactation was achieved with oral metoclopramide which was well tolerated. Alternative methods to induce lactation are reviewed. The advantages of breast-feeding and the relative ease with which lactation can be induced after a surrogate pregnancy would suggest that this cou...

The cold rolling of flat metal products especially in tandem or multi-stand mills is a highly complex process where the product quality is influenced by various aspects. With the help of a hardware-in-the-loop simulator, the complete rolling process can be simulated and tested in real-time. This allows pre-commissioning and pre-optimizations before the actual commissioning work is done on the p...

In order to carry out a successful commissioning exercise, it is important to plan the activity carefully and make sure all objectives are clear and that procedures are documented properly (Lawson, 1991; Choat, 1993). Certification programs such as LEED have helped promote commissioning and have their own particular criteria (Tseng et al., 2002). Some buildings may require formal validation pro...
