neutrino telescope

The ANTARES collaboration is building a deep underwater neutrino Cerenkov telescope at 2400 m which will be located off the Mediterranean sea coast near Toulon, France. The main scientific aims of the experiment are the detection of high energy upgoing muons coming from astrophysical neutrinos, indirect dark matter searches, the study of atmospheric neutrino oscillations. The detector will be c...

1.8-m solar telescope in China: Chinese Large Solar Telescope

For better understanding and forecasting of solar activity, high resolution observations for the Sun are needed. Therefore, the Chinese Large Solar Telescope (CLST) with a 1.8-m aperture is being built. The CLST is a classic Gregorian configuration telescope with an open structure, alt-azimuth mount, retractable dome, and a large mechanical de-rotator. The optical system with an all reflective ...

Space telescope Imaging Spectrograph

We acquired spectra of 24 LMC PNe in the 1150–3000 Å range in order to determine carbon and other ionic abundances. The sample more than doubles the number of LMC PNe with good quality UV spectra in this wavelength range, and whose optical images are available in the HST archive. The Space Telescope Imaging Spectrograph was used with a very large aperture to obtain virtually slit-less spectra, ...

The Cat Imaging Telescope

The VHE gamma-ray imaging telescope CAT started taking data in October 1996. Located at the Themis solar site in southern France (2E, 42N, 1650 m a.s.l), it features a 17.7 m2 Davies-Cotton mirror equipped with a 600 PMT camera at the focal plane. The mechanics and optics, the PMTs and the electronics are presented. The performance, based on the first 7 months of operation, is described. INTROD...
