Mobile dry pumping stations for PETRA III beamlines

Electromagnetic Simulations for the PETRA III BPMs

1.1. PETRA III: PETRA III is a new high-brilliance synchrotron radiation source to be built at DESY, Hamburg [1]. Planned to start operation in 2009, the facility will have 14 beam lines spread along one eighth of its circumference. 40 to 960 bunches with a current of 100 mA and an emittance of 1 nm·rad will be circulated at 6 GeV. The topping up operation will ensure a stable beam. 235 beam po...

Residual Gas X-ray Beam Position Monitor for Petra-iii

The development effort is driven by the need for a new type of x-ray beam position monitor, which can detect the centre of gravity of the undulator beam. A residual gas xray beam position monitor for the PETRA III storage ring was developed and tested.

A Framework for Modeling and Control of Wastewater Pumping Stations

In waste water pumping stations, centrifugal pumps driven by induction motors are used to transport the effluent collected from residential and commercial buildings to the treatment plants. Due to the varying nature of collected effluent rate, means of pump flow control should be applied. Recently, there is an engineering debate on either recommending frequency converters control or on-and-off ...

Energy Savings Potential for Pumping Water in District Heating Stations

In district heating stations, the heat carrier is circulated between the energy source and consumers by a pumping system. Fluid handling systems, such as pumping systems, are responsible for a significant portion of the total electrical energy use. Significant opportunities exist to reduce pumping energy through smart design, retrofitting, and operating practices. Most existing systems requirin...
