Jovian sodium nebula and Io plasma torus S$^+$ and brightnesses 2017 -- 2023: insights into volcanic vs. sublimation supply
We present first results derived from the largest collection of contemporaneously recorded Jovian sodium nebula and Io plasma torus (IPT) in [S II] 673.1 nm images assembled to date. The data were recorded by the Planetary Science Institute's Io Input/Output observatory (IoIO) and provide important context to Io geologic and atmospheric studies as well as the Juno mission and supporting observations. Enhancements in the observed emission are common, typically lasting 1 -- 3 months, such that th…

Almost fifty years of Metsähovi solar observations on 37 GHz with recovered digitised historical maps
Context. Aalto University Metsähovi Radio Observatory has collected solar intensity maps for over 45 years. Most data coverage is on the 37 GHz frequency band, tracking emissions primarily at the chromosphere and coronal transition region. The data spans four sunspot cycles or two solar magnetic cycles. Aims. We present solar maps, including recently restored data prior to 1989, spanning 1978 to 2020 after correcting for observational and temporal bias. Methods. The solar maps consist of radio…

Physics, scientific investigation and society in Argentina, 1920-1930
We analyse the scientific research carried out at the Institute of Physics of the National University of La Plata in the first half of the 20th century, and the cultural and social context in which they were immersed. We focus especially on the activities carried out by the Argentine physicist Ramon G. Loyarte, who was an emblematic personality in the scientific, educational, cultural and political world of Argentina in those years. We discuss his most important works in experimental physics an…

Stable Acceleration of a LHe-Free Nb3Sn demo SRF e-linac Based on Conduction Cooling
The design, construction, and commissioning of a conduction-cooled Nb3Sn demonstration superconducting radio frequency (SRF) electron accelerator at the Institute of Modern Physics of the Chinese Academy of Sciences (IMP, CAS) will be presented. In the context of engineering application planning for Nb3Sn thin-film SRF cavities within the CiADS project, a 650MHz 5-cell elliptical cavity was coated using the vapor diffusion method for electron beam acceleration. Through high-precision collaborat…
