1329 Nigel Hawkes LONDON GP commissioning consortiums in England will be obliged to include two lay members, a hospital specialist, and a nurse on their boards, the government has announced. Their name will be changed from GP or GP led consortiums to “clinical commissioning groups,” and they will be required to meet in public and publish their minutes. To avoid conflicts of interest the nurse a...

The accelerator part of the clinical facility for cancer therapy HIT using energetic proton and ion beams (C, He and O) has been installed during 2006 at the Radiologische Universitätsklinik in Heidelberg, Germany [1]. The commissioning of the injector linac was performed in three steps for the LEBT, the RFQ and the IH-DTL and has successfully ended in December 2006. Some major results are brie...

In the rapid cycling synchrotron of China Spallation Neutron Source, anti-correlated painting was adopted for design scheme injection system. beam commissioning, with optimization painting,the loss has been well controlled and efficiency exceeded 99%. Combined other aspects adjustments, power on target reached 50 kW smoothly. this paper, we have studied in commissioning. Compared to simulation ...

BACKGROUND Since 1991, there has been a series of reforms of the English National Health Service (NHS) entailing an increasing separation between the commissioners of services and a widening range of public and independent sector providers able to compete for contracts to provide services to NHS patients. We examine the extent to which local commissioners had adopted a market-oriented (transact...

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...

Scientists often develop techniques that have obvious benefits for patients but then find great difficulty in introducing them into the National Health Service-usually because the necessary finance does not seem to be available. This article provides a practical guide.

bERLinPro is an energy recovery linac project whose goal is to establish the accelerator physics knowledge and technology needed to produce 50 MeV beams with high current, low normalized emittance, and low losses. The machine will be commissioned in phases beginning in 2018, and extensive planning is underway for start-up of the machine and to prepare for measurements to verify the achievement ...

The resolution of multileaf collimators (MLCs) is limited by their finite leaf width. A commercial package (HD-270) uses 3D couch translation and leaf adjustments to emulate smaller leaf widths. In this paper, we report on the commissioning of this feature using software testing, dial gauge measurements, and film dosimetry. We also identify a variety of limitations: software bugs and truncation...
