A multiple-reflection time-of-flight (MR TOF) mass spectrometer for mass measurements of superheavy elements is currently being developed for an experimental cave of the Superheavy Element Factory at the Joint Institute for Nuclear Research in Dubna. Its conceptual and ion-optical designs are described in the present paper. The spectrometer is designed to achieve a mass measurement accuracy of 10-7 at low measurement statistics (∼5 events) for nuclides with half-lives down to 50 ms. To reach this goal, a new generation MR TOF analyzer with an ultra-high mass resolving power and highly-stable power supplies has been designed. An advanced set of ion-optical solutions for preparation and mass separation of the sample and calibrant ion beams is proposed for the spectrometer: a radiofrequency multiplexer trap separator of charge states, high vacuum quadrupole filters with two-stage differential pumping, operated in the “beat node coincidence” mode, a focused beam transport through the gate valve gaps, as well as a fullerene soot electron ionization calibrant ion source.

Composites based on graphene and nanosized silicon have recently been of interest in various applications. This paper reports a new method of synthesising a graphene-nano silicon composite material by spraying a mixture of quartz-graphite using an electric arc. The structure and composition of the materials obtained depends on the synthesis conditions. The quality of the graphene structure depends on the concentration of quartz in the load. Higher SiO 2 content leads to the production of more structured graphene. In this case, silicon is present in the materials in the form of carbide nanoparticles deposited on graphene planes. When sputtering pure quartz contained in the cavity of the graphite anode, silicon whiskers form during the synthesis process. The content of the silicon structure depends on the arc current and the sputtering rate of the anode material. The mechanisms that lead to the formation of the graphene structure and silicon whiskers in the condensation process of the products of the electric arc spraying of the anode material are considered.
