ABSTRACT: The International Design Study for the Neutrino Factory (the IDS-NF) was
established by the community at the ninth "International Workshop on Neutrino
Factories, super-beams, and beta- beams" which was held in Okayama in August
2007. The IDS-NF mandate is to deliver the Reference Design Report (RDR) for
the facility on the timescale of 2012/13. In addition, the mandate for the
study [3] requires an Interim Design Report to be delivered midway through the
project as a step on the way to the RDR. This document, the IDR, has two
functions: it marks the point in the IDS-NF at which the emphasis turns to the
engineering studies required to deliver the RDR and it documents baseline
concepts for the accelerator complex, the neutrino detectors, and the
instrumentation systems. The IDS-NF is, in essence, a site-independent study.
Example sites, CERN, FNAL, and RAL, have been identified to allow site-specific
issues to be addressed in the cost analysis that will be presented in the RDR.
The choice of example sites should not be interpreted as implying a preferred
choice of site for the facility.

ABSTRACT: The conclusions of the Physics Working Group of the International Scoping Study of a future Neutrino Factory and super-beam facility (the ISS) are presented. The ISS was carried out by the international community between NuFact05, (the 7th International Workshop on Neutrino Factories and Super-beams, Laboratori Nazionali di Frascati, Rome, 21–26 June 2005) and NuFact06 (Ivine, CA, 24–30 August 2006). The physics case for an extensive experimental programme to understand the properties of the neutrino is presented and the role of high-precision measurements of neutrino oscillations within this programme is discussed in detail. The performance of second-generation super-beam experiments, beta-beam facilities and the Neutrino Factory are evaluated and a quantitative comparison of the discovery potential of the three classes of facility is presented. High-precision studies of the properties of the muon are complementary to the study of neutrino oscillations. The Neutrino Factory has the potential to provide extremely intense muon beams and the physics potential of such beams is discussed in the final section of the report.

ABSTRACT: This report summarises the conclusions from the detector group of the International Scoping Study of a future Neutrino Factory and Super-Beam neutrino facility. The baseline detector options for each possible neutrino beam are defined as follows: A very massive (Megaton) water Cherenkov detector is the baseline option for a sub-GeV Beta Beam and Super Beam facility. There are a number of possibilities for either a Beta Beam or Super Beam (SB) medium energy facility between 1–5 GeV. These include a totally active scintillating detector (TASD), a liquid argon TPC or a water Cherenkov detector. A 100 kton magnetized iron neutrino detector (MIND) is the baseline to detect the wrong sign muon final states (golden channel) at a high energy (20–50 GeV) neutrino factory from muon decay. A 10 kton hybrid neutrino magnetic emulsion cloud chamber detector for wrong sign tau detection (silver channel) is a possible complement to MIND, if one needs to resolve degeneracies that appear in the δ-θ13 parameter space.

ABSTRACT: This document reports on a series of experimental and theoretical studies conducted to assess the astro-particle physics potential of three future large scale particle detectors proposed in Europe as next generation underground observatories. The proposed apparatuses employ three different and, to some extent, complementary detection techniques: GLACIER (liquid argon TPC), LENA (liquid scintillator) and MEMPHYS (water Cherenkov), based on the use of large mass of liquids as active detection media. The results of these studies are presented along with a critical discussion of the performance attainable by the three proposed approaches coupled to existing or planned underground laboratories, in relation to open and outstanding physics issues such as the search for matter instability, the detection of astrophysical neutrinos and geo-neutrinos and to the possible use of these detectors in future high intensity neutrino beams.

ABSTRACT: An experiment observing underground muons originating from cosmic-ray air showers is under preparation in the Pyhäsalmi mine,
Finland. The aim is to cover an area of about 200–300 m2, and the detector setup is capable of measuring the muon multiplicity and their lateral distribution. The detector is placed
at a depth of about 85 m (corresponding about 240 m w.e.), which gives a threshold energy of muons of about 45 GeV. The detection
of the multimuon events is motivated by partly unknown composition of the primary cosmic rays in the energy region of 1015–1016 eV, i.e., the knee region. In addition, by measuring only the higher energy muons of the air shower, the lowest energy muons
being filtered out by the rock overburden, the data is sensitive also to the studies of the upper parts of the air shower.
The experiment will be constructed mainly using drift chambers used previously in LEP detectors at CERN, but it can also be
expanded using plastic scintillator detectors. The prototype detector is expected to be running in the beginning of 2006,
and the full-size detector by the end of 2007.

ABSTRACT: A new type of cosmic-ray experiment is under construction in the Pyh\"asalmi mine in the underground laboratory of the University of Oulu, Finland. It aims to study the composition of cosmic rays at and above the knee region. The experiment, called EMMA, will cover approximately 150 square-metres of detector area. The array is capable of measuring the multiplicity and the lateral distribution of underground muons, and the arrival direction of the air shower. The full-size detector is expected to run by the end of 2007. Comment: Extended and updated TAUP2005 Proceedings contribution. 8 pages, 5 figures (part in colour). Preprint not submitted

ABSTRACT: The cosmic-ray induced muon flux was measured at several depths in the Pyh\"asalmi mine (Finland) using a plastic scintillator telescope mounted on a trailer. The flux was determined at four different depths underground at 400 m (980 m.w.e), at 660 m (1900 m.w.e), at 990 m (2810 m.w.e) and at 1390 m (3960 m.w.e) with the trailer, and also at the ground surface. In addition, previously measured fluxes from depths of 90 m (210 m.w.e) and 210 m (420 m.w.e) are shown. A relation was obtained for the underground muon flux as a function of the depth. The measured flux follows well the general behaviour and is consistent with results determined in other underground laboratories. Comment: 8 pages, 2 figures. Submitted to Nuclear Instrum. Methods A

ABSTRACT: We study the beamline properties of a long baseline neutrino-oscillation experiment from CERN to the Pyhasalmi Mine in Finland. We obtain the real density profile for this particular neutrino oscillation beamline by applying the geophysical data. The effects of the matter density to neutrino oscillations are considered. Also we compare the realistic density profile with that acquired from the PREM model.

ABSTRACT: From February to March 1989 the Phobos 2 spacecraft took 37 TV images of Phobos at a distance of 190–1100 km. These images complement Mariner-9 and Viking data by providing higherresolution coverage of a large region West of the crater Stickney (40–160°W) and by providing disk-resolved measurements of surface brightness at a greater range of wavelengths and additional phase angles. These images have supported updated mapping and characterization of large craters and grooves, and have provided additional observations of craters' and grooves' bright rims. Variations in surface visible/nearinfrared color ratio of almost a factor of 2 have been recognized ; these variations appear to be associated with the ejecta of specific large impact craters. Updated determinations of satellite mass and volume allow calculation of a more accurate value of bulk density, 1.90 ± 0.1 g cm−3. This is significantly lower than the density of meteoritic analogs to Phobos' surface, suggesting a porous interior perhaps containing interstitial ice.

ABSTRACT: A new cosmic-ray experiment is under construction in the Pyhäsalmi mine, Finland. It aims to study the chemical composition of cosmic rays at and above the knee region. The array, called EMMA, will cover approximately 150 m2 of detector area at the depth of 85 metres (∼240 mwe). It is capable of measuring the multiplicity and the lateral distribution of underground muons, and the arrival direction of the air shower. The full-size array is expected to be ready by the end of 2007. A partial-size array (one third of the full size) is planned to record data already at the first quarter of 2007. The array is also expected to be capable of measuring such high-multiplicity muon bundles as was observed at the cosmic-ray experiments at the LEP detectors.

ABSTRACT: A large liquid-scintillator detector with 50 kt target mass in an underground location of at least 4000 m.w.e. is considered as a unique tool for low-energy neutrino detection and the search for rare events from astrophysical sources and up to now unobserved processes beyond the Standard Model. In this contribution, the physics potential of LENA for selected topics is discussed.

ABSTRACT: An experiment to observe simultaneous, multiple muon events originating from extensive air showers is under preparation. The experiment will be situated in shallow depths in the Pyhäsalmi mine in Finland, where the existing free caverns will be used. The aim is to cover an area of about 200−300 m2. The detection of the multimuon events is motivated by partly unknown composition of the primary cosmic rays in the energy region of 1015−1016 eV, i.e. the 'knee' region. A prototype detector is under construction and is expected to be running at the spring 2005.
