A Novel Approach to β-Decay: PANDORA, a New Experimental Setup for Future In-Plasma Measurements

David Mascali et al.

Summary: This paper introduces an innovative method using a compact plasma trap to simulate stellar conditions and measure the nuclear beta-decay rates of radionuclides. The plasma trap, designed with specific parameters, will monitor plasma parameters and detect gamma-rays emitted from the excited daughter nuclei to measure the decay rates. Additionally, the plasma trap can also be used to measure plasma opacities and their impact on energy transport and spectroscopic observations of astrophysical objects.

Microwave techniques for electron cyclotron resonance plasma diagnostics

David Mascali et al.

Summary: This paper provides a review of the main microwave diagnostic techniques and tools used in electron cyclotron resonance (ECR) ion source laboratories, with a focus on techniques developed at INFN-LNS. It discusses optimization tools such as power monitors, spectral analysis, and network analyzers, as well as devices developed for in-plasma analysis. The paper also examines the implications and interplays of microwave techniques in multidiagnostic systems, particularly in time resolved microwave measurements and advanced signal processing.

Design and characterization of a single-channel microwave interferometer for the Helicon Physics Prototype eXperiment

X. L. Li et al.

Summary: A heterodyne interferometer has been developed and characterized for measuring plasma electron density in Helicon Physics Prototype eXperiment (HPPX). The system utilizes two Gunn oscillators for frequency modulation, achieving a cutoff density of 8.96 x 10(19) m(-3). The characterization results show good performance of the lens and critical microwave components, with the plasma electron density measurement results aligned with expectations, demonstrating an SNR of 80 dB for clear and detailed density resolution.

Performance Assessment of W-Band Radiometers: Direct versus Heterodyne Detections

Juan Pablo Pascual et al.

Summary: Two W-Band radiometer designs, one using intermediate frequency down-conversion and the other using direct detection, are compared in terms of performance. The direct detection scheme shows slightly better noise performance and wider bandwidth compared to the super-heterodyne implementation.
