One usually thinks of it as a spherical shell about one astronomical unit (AU) in radius, and surrounding a more or less Sun-like star; and might be detectable as an infrared point source. We point out that Dyson Spheres could also be built around white dwarfs. This type would avoid the need for artificial gravity technology, in contrast to the AU-scale Dyson Spheres. In fact, we show that parameters can be found to build Dyson Spheres suitable-temperatureand gravity-wise-for human habitation. This type would be much harder to detect.

For the first phase, 20 keV protons will be accelerated to 1.3 MeV by a single piece RFQ. Currently, the beam current and stability tests are ongoing for the Inductively Coupled Plasma ion source. The measured magnetic field maps of the Low Energy Beam Transport solenoids are being used for matching various beam configurations of the ion source to the RFQ by computer simulations. The installation of the low energy diagnostics box was completed in Q1 of 2015. The production of the RFQ cavity was started with aluminum 7075-T6 which will be subsequently coated by Copper to reduce the RF (Ohmic) losses. On the RF side, the development of the hybrid power supply based on solid state and tetrode amplifiers continues. All RF ...
