Hot Jets in the Solar Corona: Creating a Catalogue of Events Based on Multi-Instrumental Observations

We present a catalogue of solar coronal plasma jets with a temperature above 0.5 MK, which includes primary information about the events, parameters of the diagnosed jets, as well as related eruptive phenomena. The catalogue (https://solar.sao.ru/coronal-jets-catalog/) contains data obtained using the spaceborne EUV high-precision telescope SDO/AIA and ground-based radio telescopes and spectrometers, including RATAN-600, SRH and NoRH. For a number of events data on the reconstructed magnetic field is also presented. The purpose of the catalogue is to provide summary information on coronal jets for further statistical analysis, determination of characteristic parameters of jets, and for in-depth study of the individual events by all interested researchers

Diagnostics of Plasma Jets in the Solar Corona

The paper discusses the diagnostics of plasma jets in the solar corona with the use of data from modern space- and ground-based telescopes observing the Sun in the extreme ultraviolet (EUV) and micro- wave bands. We examine observational parameters of EUV and radio emission in events associated with plasma jets, depending on the mechanism of formation, initiation conditions, and evolution of the jets. The opportunities provided by the study of plasma jets, which relies on simultaneous observations in different bands, are highlighted. For a number of jets, we have measured their primary parameters; and in this paper we present preliminary results of statistical processing of the data obtained. Microwave observations of several specific events, made by ground-based instruments RATAN-600, SRH, and Nobeyama Radioheliograph, are considered in detail. The diagnostic capabilities of these instruments for studying coronal jets are shown. To analyze the three-dimensional structure of the coronal magnetic field, we have used SDO/HMI data, which allowed for the reconstruction of the field in the lower corona. The information gained is compared with the results of diagnostics of the magnetic field at the base of the corona according to RATAN-600 data. The purpose of the methods developed is to determine the physical mechanisms responsible for the generation, collimation, and dynamics of plasma jets in the solar atmosphere

Characterization of ion species mix of the TEXTOR diagnostic hydrogen beam injector with a rf and arc-discharge plasma box

The ion specie fractions of the diagnostic hydrogen beam of TEXTOR tokamak have been determined by making use of a H-alpha-light Doppler shift spectroscopy and alternatively by a magnetic mass spectrometer. The measurements were done for the fixed beam energy of 50 keV and beam current variable up to 2.5 A. According to the measurements, the full energy beam component is for a radio frequency plasma box similar to50% by the particle density and more than 75% for an arc-discharge plasma box.
