In case of performing so-called PET acquisition, a nuclear medical diagnosis apparatus according to the present invention does not set only gamma rays which imparted predetermined energy values (for example, energy values of and above a Compton edge), as subjects for coincidental counting acquisition (coincidence acquisition), but it discriminates also further gamma rays which caused a photoelectric effect after having undergone Compton scattering once in a radiation detection unit, so as to set them as subjects for the coincidental counting acquisition. Concretely, if the added value of energy values observed in two detection elements is near 511 keV, the existence of the further gamma ray is presumed, and the acquisition thereof is possible. Besides, that one of the two detection elements as to which energy near the Compton edge is observed can be specified as the incident position of the gamma ray on the radiation detection unit.

There are provided: a compression puffer chamber (12) for accumulating pressurized gas (35) that is obtained by elevating the pressure of the arc-extinguishing gas (1); and an insulated nozzle (32) that directs the pressurized gas (35) towards the arc discharge (7) from the compression puffer chamber (12). A buffer chamber (36) is provided, in which hot exhaust gas (20) generated by the heat of the arc discharge (7) is temporarily accumulated. A pressurized gas through-flow space (43) is provided, communicating with the compression puffer chamber (12) . In the pressurized gas through-flow space (43), an opening/closing section (41) prevents inflow of hot exhaust gas (20) by assuming a closed condition during the earlier half of the current interruption period, and in the latter half of the current interruption period the opening/closing section 41 is opened to allow flow of pressurized gas (35).

We propose to forge a partnership between the leading European groups working on the next generation of solid state quantum emitters based on novel growth methods such as Droplet Epitaxy. Future, practical Nano-photonics and Quantum Circuits applications demand semiconductor quantum dots that can be grown on substrates with different lattice parameters (Si, Ge, GaAs), different substrate orientations (such as (001) and (111)) and tuneable optical, electrical and spin properties. All these requirements are met by high quality quantum dots grown with Droplet based Epitaxy techniques, circumventing the limitations of currently available systems based on strain-driven dot self-assembly. This vast novel research area at the crossroads of photonics, material science, quantum physics and nano-scale device fabrication will allow delivering top level multidisciplinary training to 15 early stage researcher (ESRs). The successful training of the ESRs by leading academic and 3 full industrial partners will be crucial for achieving the headline goals of this first ever consortium on droplet dot devices: (1) Entangled light emitting diodes with droplet dots grown on (111) substrates (2) Electrically triggered, droplet dot based single photon sources on Si/Ge substrates (3) Strain tuning in droplet dots without wetting layer: photon polarization and single spin control (4) Droplet Dot based single photon sources for non- classical light storage devices based on hybrid quantum systems (dots & laser-cooled atoms). The training and research progress will be discussed and monitored during the 4 project meetings, 3 summer schools and the final international conference on Droplet Dot Devices, all of which are open to the whole scientific community. We expect this network, based on the solid collaboration between growth groups, microscopists, quantum optics experimentalists and theorists to explore the full potential of this emerging technology.
