The ENERCON Desalination Department has developed a new energy recovery system for RO desalination plants, optimized for the combination with wind energy converters. The main problem for the combination of desalination processes and wind energy is the fluctuation of power supply generated through renewable energies. Conventional desalination plants (and the belonging energy recovery systems) wo...

It is demonstrated that recovery of the electromagnetic energy of the fundamental mode at the output of an acceleration structure leads to a significant efficiency enhancement. When using a single bunch, the number of electrons accelerated is rather small. In fact, this number is virtually identical to the case when no feedback loop is employed. To increase this number, in parallel with the eff...

Three decades ago, theoretical physicists suggested that the controlled recovery of charges could result in electronic circuitry whose power dissipation approaches thermodynamic limits, growing at a significantly slower pace than the fCV 2 rate for CMOS switching power. Early engineering research in this field, which became generally known as adiabatic computing, focused on the asymptotic energ...

Energy harvesting systems such as self-powered wireless sensor nodes rely on a diverse set of energy sources in their continuously changing environment for power. A highly flexible power supply with multiple sources is needed to deal with large variation in environmental conditions. This paper describes an integrated power management system for use with multiple energy harvesters, which employs...

Many of the challenges associated with operating a Superconducting RF (SRF) Energy Recovery Linac (ERL) are independent of the choice of operating frequency, beam energy, and overall purpose of the machine. Worldwide there are an increasing number of ERLs in various stages of development and operation which are facing a number of similar challenges and often solving them in very different ways....
