Abstract

KM3NeT/ORCA is a dense array that constitutes the low-energy branch of the KM3NeT project with the main goal of resolving the question of the neutrino mass ordering. At present, the KM3NeT/ORCA Phase 1 has already been deployed, which means that six out of the planned 115 detection lines are operational. Even with this limited configuration, neutrino oscillations can already be measured and studied. In this contribution, the sensitivity to the neutrino Non-Standard Interactions (NSI) parameter $\epsilon_{\mu \tau}$ using the current stage of the KM3NeT/ORCA detector together with the projections for the final configuration are presented.

Abstract

Summary form only given. Overcoming the spatial resolution limitations in optical microscopy due to the diffraction of light has become a major challenge in modern microscopy. To overcome this limit, we demonstrate here the upconversion process in rare-earth-doped fluoride nanoparticles (RE:NPs) that may serve as novel sources for fluorescent microscopy. RE:NPs have been reported to serve as efficient biolabels for cellular and small animal imaging [1]. While almost all work devoted to RE doped nanocrystals in biological applications had investigated NaYF4, here we performed experiments with LaF3 and KY3F10, other possible materials to host upconversion. Specifically, (2at.%) Er3+, (2at.%) Yb3+: KY3F10, (1at.%) Tm3+, (6at.%) Yb3+: LaF3 and (0.5at.%) Tm3+, (12at.%) Yb3+: KY3F10 20-50 nm-sized crystals had been characterized using AFM, STEM, X-ray diffraction and dynamic light scattering techniques and investigated by luminescence spectroscopy and nonlinear optical microscopy [2]. The latter was done on NP's dispersed in PEG and spun-coated on a glass cover slip. One of the fluorescence images produced with upconversion process in these nanoparticles is presented in Fig. 1. The increase of the photon process order and the corresponding decrease in the full width of half-maximum (FWHM) of intensity point spread function (IPSF) value can be clearly observed. As the result of the photon process order, N, increase, the instrument's optical resolution becomes: Δx, ΔY ≅ 0.61λ/NA√N (1) where λ is the excitation wavelength and NA is the objective's numerical aperture.Whereas the resolution of a mul tipho ton microscopy does not exceed λ 3 in the lateral directions [3], in our study we demonstrate that the FWHMIPsF can be down-scaled up to 297nm for a two-photon process, 239nm for a three-photon process, and /90nm for a four-photon process, corresponding respectively to λ 3.29 , λ 4.29 and λ 5.15 improvement in the resolution. Our experimental results demonstrate several advantages of RE:NPs nanoparticles over conventional bio and medical imaging probes: low backgrounds noise due to near infrared excitation, low power (μW) excitation, and absence of photo-blinking and pho tobleaching. This technique together with the detection of the two-, three-, and four-photon processes at single particle level open new opportunities in single-molecule tracking applications in biology as well as novel low-cost high-resolution optical microscopy systems.

Abstract

The Worldwide LHC Computing Grid relies on the network as a critical part of its infrastructure and therefore needs to guarantee effective network usage and prompt detection and resolution of any network issues, including connection failures, congestion, traffic routing, etc. The WLCG Network and Transfer Metrics project aims to integrate and combine all network-related monitoring data collected by the WLCG infrastructure. This includes FTS monitoring information, monitoring data from the XRootD federation, as well as results of the perfSONAR tests. The main challenge consists of further integrating and analyzing this information in order to allow the optimizing of data transfers and workload management systems of the LHC experiments. In this contribution, we present our activity in commissioning WLCG perfSONAR network and integrating network and transfer metrics: We motivate the need for the network performance monitoring, describe the main use cases of the LHC experiments as well as status and evolution in the areas of configuration and capacity management, datastore and analytics, including integration of transfer and network metrics and operations and support.

Abstract

A major bottleneck in microscopic imaging is the limited lateral resolution due to the diffraction of light. To overcome this limit, here we demonstrate the upconversion process in rare earth doped nanoparticles (RE:NPs), which may serve as an original fluorescence-source mechanism. RE:NPs have been reported to serve as efficient bio-labels for cellular and small animal imaging. In this work, we demonstrate that non-linearity of upconversion allows achieving high lateral resolution in the images using multiphoton microscopy, demonstrating significant improvement in lateral resolution, using low pumping laser power. This new technique may serve as another approach for high-resolution optical imaging.
