Spectroscopic observation of solar flares in the hard X-ray energy range, particularly the 20 ∼ 100 keV region, is an invaluable tool for investigating the flare mechanism. This paper describes the design and performance of a balloon-borne hard X-r

Astronomy education needs flexible education programs in accordance with various seasonal phenomena. However, panels or exhibits in science museums are often too static to behave dynamically to serve the purpose. In this paper, we represent a method

We report on the analysis of a thermal flare observed by a newly developed balloon-borne hard X-ray spectrometer. This instrument uses CdTe detectors and can observe the 20-120 keV hard X-ray range, with 3.0 keV energy resolution at 60 keV. During th

Extreme ultraviolet (EUV, λ=13.5 nm) lithography is expected as the next generation lithography to the ArF immersion lithograph (λ =193 nm ). Projection optics is composed of several aspheric mirrors and its aberration should be about 1/30λ rms (0

Stimulated Raman scattering (SRS) microscope has enabled label-free rapid Raman spectral imaging. Recent studies have reported video-rate imaging with a pixel clock of over 10 MHz [1, 2]. However, these systems require expensive and bulky devices suc

Cell performances of Cu(In,Ga)Se 2 (CIGS) thin-film solar cells were measured and analyzed as a function of temperature and illumination. The J sc and V oc were linearly changed with the temperature in the range of 10°C–70°C, and the J sc was pro
