“…For a particle with L tr = 1 cm, the angular resolution would be better than σ angle = 0.06 mrad. The neutrino event analysis will be based on readout of the full emulsion detectors by the Hyper Track Selector (HTS) system [91]. HTS has a readout speed of 0.5 m 2 /h/layer, which makes it possible to analyze 1000 m 2 /year of doublesided emulsion films effectively.…”

Neutrinos are copiously produced at particle colliders, but no collider neutrino has ever been detected. Colliders produce both neutrinos and anti-neutrinos of all flavors at very high energies, and they are therefore highly complementary to those from other sources. FASER, the Forward Search Experiment at the LHC, is ideally located to provide the first detection and study of collider neutrinos. We investigate the prospects for neutrino studies with FASERν, a proposed component of FASER, consisting of emulsion films B. Denton and Callum Wilkinson: FASER Associate.

“…Emulsion detectors and the automated readout systems have been successfully employed by several neutrino experiments such as CHORUS [42], DONuT [6,7] and OPERA [8]. The latest scanning system, the HTS system [33,34], allows scanning of the emulsion films at the speed of 5,000 cm 2 per hour per emulsion layer, which is O(100) faster than those used in OPERA. The high performance is achieved by combining a custom-made wide-field objective lens and 72 high-speed image sensors.…”

In the DsTau experiment at the CERN SPS, an independent and direct way to measure tau neutrino production following high energy proton interactions was proposed. As the main source of tau neutrinos is a decay of D s mesons, produced in proton-nucleus interactions, the project aims at measuring a differential cross section of this reaction. The experimental method is based on a use of high resolution emulsion detectors for effective registration of events with short lived particle decays. Here we present the motivation of the study, details of the experimental technique, and the first results of the analysis of the data collected during test runs, which prove feasibility of the full scale study of the process in future.

“…The data analysis will require the full-area scanning of the 1000-m 2 emulsion surface by the world's fastest readout system, the Hyper Track Selector (HTS) [5]. After detecting τ-decay topologies, events will be analyzed by dedicated high-precision systems using a piezo-based highprecision Z-axis, allowing emulsion hits to be measured with a nanometric resolution.…”

Lepton universality in tau-neutrino (ν τ ) scattering has been poorly tested. More precise measurement of the ν τ cross section would enable a search for new physics effects in ν τ -nucleon CC interactions. Such measurement also has practical importance for next-generation neutrino oscillation experiments and astrophysical ν τ observations. The DsTau project has been proposed at CERN SPS to study tau-neutrino production with the aim of providing important data for future ν τ measurements. For ν τ cross section measurements, the practical method of producing an artificial ν τ beam employs the sequential decay of D s mesons produced in high-energy proton interactions. However, there has been no experimental measurement of the D s differential production cross section in fixed-target experiments using proton beams, which leads to a large systematic uncertainty on the ν τ flux estimation. The DsTau project aims to reduce this uncertainty in the current cross section measurement from about 50% to 10% by measuring the D s differential production cross section. For this purpose, emulsion detectors with a 50-nm spatial resolution will allow the detection of D s → τ → X double kinks in a few mm range. Results from the beam tests conducted in 2016-2017 are presented together with a prospect for the pilot run in 2018 and the physics run in 2021.
