	Title	The ANTARES telescope neutrino alert system			Type	Journal Article
	Year	2012	Publication	Astroparticle Physics	Abbreviated Journal	Astropart Phys.
	Volume	35	Issue	8	Pages	530-536
	Keywords	ANTARES; Neutrino astronomy; Transient sources; Optical follow-up
	Abstract	The ANTARES telescope has the capability to detect neutrinos produced in astrophysical transient sources. Potential sources include gamma-ray bursts, core collapse supernovae, and flaring active galactic nuclei. To enhance the sensitivity of ANTARES to such sources, a new detection method based on coincident observations of neutrinos and optical signals has been developed. A fast online muon track reconstruction is used to trigger a network of small automatic optical telescopes. Such alerts are generated for special events, such as two or more neutrinos, coincident in time and direction, or single neutrinos of very high energy.

	Title	Performance of the front-end electronics of the ANTARES neutrino telescope			Type	Journal Article
	Year	2010	Publication	Nuclear Instruments & Methods in Physics Research A	Abbreviated Journal	Nucl. Instrum. Methods Phys. Res. A
	Volume	622	Issue	1	Pages	59-73
	Keywords	Neutrino telescope; Photomultiplier tube; Front-end electronics; ASIC
	Abstract	ANTARES is a high-energy neutrino telescope installed in the Mediterranean Sea at a depth of 2475 m. It consists of a three-dimensional array of optical modules, each containing a large photomultiplier tube. A total of 2700 front-end ASICs named analogue ring samplers (ARS) process the phototube signals, measure their arrival time, amplitude and shape as well as perform monitoring and calibration tasks. The ARS chip processes the analogue signals from the optical modules and converts information into digital data. All the information is transmitted to shore through further multiplexing electronics and an optical link. This paper describes the performance of the ARS chip: results from the functionality and characterization tests in the laboratory are summarized and the long-term performance in the apparatus is illustrated.

	Title	Zenith distribution and flux of atmospheric muons measured with the 5-line ANTARES detector			Type	Journal Article
	Year	2010	Publication	Astroparticle Physics	Abbreviated Journal	Astropart Phys.
	Volume	34	Issue	3	Pages	179-184
	Keywords	Atmospheric muons; Neutrino telescope; Depth-intensity relation
	Abstract	The ANTARES high-energy neutrino telescope is a three-dimensional array of about 900 photomultipliers distributed over 12 mooring lines installed in the Mediterranean Sea. Between February and November 2007 it acquired data in a 5-line configuration. The zenith angular distribution of the atmospheric muon flux and the associated depth-intensity relation are measured and compared with previous measurements and Monte Carlo expectations. An evaluation of the systematic effects due to uncertainties on environmental and detector parameters is presented.

	Title	Measurement of the atmospheric muon flux with a 4 GeV threshold in the ANTARES neutrino telescope			Type	Journal Article
	Year	2010	Publication	Astroparticle Physics	Abbreviated Journal	Astropart Phys.
	Volume	33	Issue	2	Pages	86-90
	Keywords	Atmospheric muons; Depth intensity relation; Potassium-40
	Abstract	A new method for the measurement of the muon flux in the deep-sea ANTARES neutrino telescope and its dependence on the depth is presented. The method is based oil the observation of coincidence signals in adjacent storeys of the detector. This yields an energy threshold of about 4 GeV. The main sources of optical background are the decay of K-40 and the bioluminescence in the sea water. The K-40 background is used to calibrate the efficiency of the photo-multiplier tubes.

	Title	Science with Neutrino Telescopes in Spain			Type	Journal Article
	Year	2022	Publication	Universe	Abbreviated Journal	Universe
	Volume	8	Issue	2	Pages	89 - 25pp
	Keywords	neutrino; neutrino telescopes; neutrino astrophysics; neutrino properties; sea science
	Abstract	The primary scientific goal of neutrino telescopes is the detection and study of cosmic neutrino signals. However, the range of physics topics that these instruments can tackle is exceedingly wide and diverse. Neutrinos coming from outside the Earth, in association with other messengers, can contribute to clarify the question of the mechanisms that power the astrophysical accelerators which are known to exist from the observation of high-energy cosmic and gamma rays. Cosmic neutrinos can also be used to bring relevant information about the nature of dark matter, to study the intrinsic properties of neutrinos and to look for physics beyond the Standard Model. Likewise, atmospheric neutrinos can be used to study an ample variety of particle physics issues, such as neutrino oscillation phenomena, the determination of the neutrino mass ordering, non-standard neutrino interactions, neutrino decays and a diversity of other physics topics. In this article, we review a selected number of these topics, chosen on the basis of their scientific relevance and the involvement in their study of the Spanish physics community working in the KM3NeT and ANTARES neutrino telescopes.

	Title	Deep-Sea Bioluminescence Blooms after Dense Water Formation at the Ocean Surface			Type	Journal Article
	Year	2013	Publication	Plos One	Abbreviated Journal	PLoS One
	Volume	8	Issue	7	Pages	e67523 - 10pp
	Keywords
	Abstract	The deep ocean is the largest and least known ecosystem on Earth. It hosts numerous pelagic organisms, most of which are able to emit light. Here we present a unique data set consisting of a 2.5-year long record of light emission by deep-sea pelagic organisms, measured from December 2007 to June 2010 at the ANTARES underwater neutrino telescope in the deep NW Mediterranean Sea, jointly with synchronous hydrological records. This is the longest continuous time-series of deep-sea bioluminescence ever recorded. Our record reveals several weeks long, seasonal bioluminescence blooms with light intensity up to two orders of magnitude higher than background values, which correlate to changes in the properties of deep waters. Such changes are triggered by the winter cooling and evaporation experienced by the upper ocean layer in the Gulf of Lion that leads to the formation and subsequent sinking of dense water through a process known as “open-sea convection”. It episodically renews the deep water of the study area and conveys fresh organic matter that fuels the deep ecosystems. Luminous bacteria most likely are the main contributors to the observed deep-sea bioluminescence blooms. Our observations demonstrate a consistent and rapid connection between deep open-sea convection and bathypelagic biological activity, as expressed by bioluminescence. In a setting where dense water formation events are likely to decline under global warming scenarios enhancing ocean stratification, in situ observatories become essential as environmental sentinels for the monitoring and understanding of deep-sea ecosystem shifts.

	Volume	79	Issue	9	Pages	903-908
	Keywords	cloud chambers; diffusion; radiation effects; radon; student experiments
	Abstract	Radon concentration in air is a major concern in lung cancer studies. A traditional technique used to measure radon abundance is the charcoal canister method. We propose a novel technique using a diffusion cloud chamber. This technique is simpler and can easily be used for physics demonstrations for high school and university students.

	Title	Architecture and performance of the KM3NeT front-end firmware			Type	Journal Article
	Year	2021	Publication	Journal of Astronomical Telescopes, Instruments and Systems	Abbreviated Journal	J. Astron. Telesc. Instrum. Syst.
	Volume	7	Issue	1	Pages	016001 - 24pp
	Keywords	neutrino telescope; acquisition firmware; time to digital converters; KM3NeT
	Abstract	The KM3NeT infrastructure consists of two deep-sea neutrino telescopes being deployed in the Mediterranean Sea. The telescopes will detect extraterrestrial and atmospheric neutrinos by means of the incident photons induced by the passage of relativistic charged particles through the seawater as a consequence of a neutrino interaction. The telescopes are configured in a three-dimensional grid of digital optical modules, each hosting 31 photomultipliers. The photomultiplier signals produced by the incident Cherenkov photons are converted into digital information consisting of the integrated pulse duration and the time at which it surpasses a chosen threshold. The digitization is done by means of time to digital converters (TDCs) embedded in the field programmable gate array of the central logic board. Subsequently, a state machine formats the acquired data for its transmission to shore. We present the architecture and performance of the front-end firmware consisting of the TDCs and the state machine.

	Title	Expansion cone for the 3-inch PMTs of the KM3NeT optical modules			Type	Journal Article
	Year	2013	Publication	Journal of Instrumentation	Abbreviated Journal	J. Instrum.
	Volume	8	Issue		Pages	T03006 - 20pp
	Keywords	Optical detector readout concepts; Instrument optimisation; Cherenkov detectors; Large detector systems for particle and astroparticle physics
	Abstract	Detection of high-energy neutrinos from distant astrophysical sources will open a new window on the Universe. The detection principle exploits the measurement of Cherenkov light emitted by charged particles resulting from neutrino interactions in the matter containing the telescope. A novel multi-PMT digital optical module (DOM) was developed to contain 31 3-inch photomultiplier tubes (PMTs). In order to maximize the detector sensitivity, each PMT will be surrounded by an expansion cone which collects photons that would otherwise miss the photocathode. Results for various angles of incidence with respect to the PMT surface indicate an increase in collection efficiency by 30% on average for angles up to 45 degrees with respect to the perpendicular. Ray-tracing calculations could reproduce the measurements, allowing to estimate an increase in the overall photocathode sensitivity, integrated over all angles of incidence, by 27% (for a single PMT). Prototype DOMs, being built by the KM3NeT consortium, will be equipped with these expansion cones.

	Abstract	The Hamamatsu R12199-023-inch photomultiplier tube is the photodetector chosen for the first phase of the KM3NeT neutrino telescope. About 7000 photomultipliers have been characterised for dark count rate, timing spread and spurious pulses. The quantum efficiency, the gain and the peak-to-valley ratio have also been measured for a sub-sample in order to determine parameter values needed as input to numerical simulations of the detector.
