The multidisciplinary research and the broad range of basic and applied studies carried out at the Institute demanded creation of an adequate experimental base. To date the IAP RAS is a center for large-scale development and production of experimental complexes, facilities, and setups, as well as of the needed technological equipment and devices. In some areas, the IAP RAS has unique world-level capabilities for experimental research. In what follows we briefly describe the major experimental facilities of the Institute.
In plasma physics and electronics:
he "Krot" plasma facility, which combines a high-current accelerator (1.5 MeV, 10 kA, 100 ns), a set of high-power microwave oscillators, and a vacuum chamber of extremely large volume (10 m in length, 3 m in diameter), for obtaining a highly homogeneous plasma with a broad spectrum of diagnostics.
High-current electron accelerators equipped with X-ray protection, magnetic systems (with pulsed and superconducting solenoids), quasi-optical channels, diagnostic complexes, and automated systems for recording and processing of information. These include:
A complex for growing high-quality diamond films, which comprises a microwave CVD reactor that uses the pulsed microwave discharge plasma at a frequency of 2.45 GHz, a standard microwave CVD reactor with the use of a continuous microwave discharge at a frequency of 2.45 GHz, and an experimental setup for deposition of diamond films using microwave radiation of a CW gyrotron having a power of 10 kW at a frequency of 30 GHz..
