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...

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...

Beam Commissioning for the damping ring of the KEK accelerator test facility (ATF) has been started since January 1997. Control system of the ATF accelerator i s based on the CAMAC-enhanced byte-serial highways handled by the Open-VMS Cluster system. Control software is integrated by using a commercial database application for process control. In this paper we present the status of the ATF cont...

Traditionally the tuning of dynamic matrix control (DMC) type multivariable controllers is done by trial and error. The APC engineer chooses arbitrary starting values and tests the performance on a simulated controller. The engineer then either increases the values to suppress movement more, or decreases them to have the manipulated variables move faster. When the controller performs acceptably...

Revised edition 30 April 2015 Introduction The organisations commissioning health services in England changed radically in April 2013. Clinical commissioning groups (CCGs) are now responsible for the majority of the NHS budget, controlling around £69 billion in 2015/16. Public health budgets of £2.8 billion have transferred to local authorities (although this figure does not take into account t...

The RHIC Beam Abort Kicker Power Supply Systems commissioning experience and the remaining issues will be reported in this paper. The RHIC Blue Ring Beam Abort Kicker Power Supply System initial commissioning took place in June 1999. Its identical system in Yellow Ring was brought on line during Spring 2000. Each of the RHIC Beam Abort Kicker Power Supply Systems consists of five high voltage m...
