[en] The present status of the experiment can be broken into ''performance'' and ''construction''. In the area of performance, production and prototype versions of both the PDT's and calorimeters have been tested using charged particles from beams, cosmic rays and sources. The desired specifications have been met; in particular: Δthetasub(e) approximately = 12 mrad/√Ee, calorimeter attenuation lenghts approximately 200cm, and single cell dE/dx of < 50% FWHM. In the area of construction, three complete (calorimeter plus X-Y PDT's) modules per week are being produced. About one tenth of the total detector is in installation for an engineering run next month (april, 1980). In the autum (>september, 1980), data taking runs should begin on between one-half and one-third of the detector. Future plans include adding the remaining portion of the detector during the following year as well as the addition of a magnetic spectrometer for muons and downstream augmentation of gamma ray detection
[en] In Physics Today beta (Β)-decay 17 KeV Signal status is updated with a sour note on 17 KeV heavy neutrino. The fact that Β--decay 17 KeV is not a neutrino (and as such can't disturb the Standard Model) is first given in 1980, 1991-1993. Everybody knows that experiments must be unbiased with no concern for or against any theory if new laws of Physics are to be discovered. As a Physicist it seems only fair to observe that all the reported new Expts. are questionable in one way or the other, besides being biased from the heavy pressure of the Standard Model to get rid of 17 KeV neutrino. To think that 17 KeV Β--decay signal can be only a neutrino is WRONG. Bad Politics in Science will be destructive. Let us forget theory. Since the said 17 KeV Β--decay signal is absent under Mag. Spectrometers, be Pauli-like.(Cont'd)
[en] This contribution reviews the recent progress achieved towards building the ANTARES neutrino telescope. The first results obtained by the operation of a Mini Instrumentation Line with Optical Modules, “MILOM”, and the first complete detector line are highlighted.
[en] We present a review of the latest results on the oscillation mixing parameters obtained by the T2K collaboration and foreseen for the Hyper-Kamiokande experiment by the Hyper-Kamiokande Working Group
[en] In the last century, astronomy evolved from optical observation to the multi-wavelength study of celestial objects from radio waves up to x- and γ-rays, leading to a wealth of new discoveries and opening the way to high-energy astroparticle physics. In particular, the recent success of ground-based very-high-energy γ-ray telescopes has opened a new window on the most powerful and violent objects of the Universe, giving a new insight into the physical processes at work in such sources. In the context of high-energy astronomy, neutrinos constitute a unique probe since they escape from their sources, travel undisturbed on virtually cosmological distances and are produced in high-energy hadronic processes. In particular they would allow a direct detection and unambiguous identification of the sites of acceleration of high-energy baryonic cosmic rays, which remain unknown. This report discusses the physics potential of the domain and reviews the experimental techniques relevant for the detection of high-energy (≥TeV) neutrinos. The results obtained by the first generation of such detectors are presented, along with the perspectives opened by new projects and prototypes being currently developed.
[en] Be Pauli-l to assume that electromagnetic field when directly applied on the Β--decay electrons before ampersand during detection will prevent the said 17 KeV signal resolution/kink. After detection, use of electric/magnetic field for amplification, collection, etc. will have no effect upon the resolved 17 KeV signal. (WHY ? A think for later on stage.) Hence, Argonne New Expt is defective because it uses Solenoidal Mag. field in guiding Β-- rays down to the detector (--no difference from Mag. Spectrometers results). Hime intelligently ponders at the Argonne Mag. Transport system, but remains dubious and ambiguous in his own repeats of Expts. ampersand Calculations. Berkeley group in doing repeats of Expts. replace the PHYSICAL (Exptal.) GUARD-RING veto-system with UNPHYSICAL (Calculation-prone) Software fiducial Veto to find wrong null-results. Errant Guard-Ring can be properly corrected for. Simpson alone stands firm as any good experimentalist will do, and I admire him. Argonne, Berkeley, Hime ampersand Oxford are urged to redo Expts
[en] In this paper we present the upgrading of the LSD experiment, presently running in the Mont Blanc Laboratory. The data recorded during the period when supernova 1987A exploded are analysed in detail. The research program of LSD-2, the same experiment as LSD but with an higher sensitivity to search for neutrino burst from collapsing stars, is also discussed
