Aims To establish the nature, extent and organization of occupational health service provision for employees within the National Health Service (NHS) in London and to review the systems for ...monitoring performance. Methods Human resources directors and occupational health managers were contacted from a random selection of NHS trusts in the London area and invited to complete an interviewer-led questionnaire. Results All seventeen trusts interviewed claimed to provide an occupational health service to their employees, with 88% providing this service in-house. The organization of the services varied, although most resided within the human resources function. Only 29% of the trusts could provide a written occupational health policy. Teaching hospital trusts had the most qualified and the highest numbers of medical staff. District/General hospital trusts had the least qualified clinical staff. Although most trusts were able to provide a comprehensive range of services, 87% of occupational health managers felt they could only provide a reactive service. Income was generated from non-NHS sources by 88% of the trusts and all were aware of NHS Plus. There was an indication that some trusts assigned NHS Plus status did not meet the standard of NHS Plus, although the survey took place only 3 months after the launch of NHS Plus. Conclusions There was a significant variation in the nature and extent of occupational health services in the NHS trusts. As a consequence, there may be differences in the level of occupational health service available to staff across the NHS in London.
Using an 185-kg NaITl array, COHERENT has measured the inclusive electron-neutrino charged-current cross section on ^{127}I with pion decay-at-rest neutrinos produced by the Spallation Neutron Source ...at Oak Ridge National Laboratory. Iodine is one the heaviest targets for which low-energy (≤50 MeV) inelastic neutrino-nucleus processes have been measured, and this is the first measurement of its inclusive cross section. After a five-year detector exposure, COHERENT reports a flux-averaged cross section for electron neutrinos of 9.2_{-1.8}^{+2.1}×10^{-40} cm^{2}. This corresponds to a value that is ∼41% lower than predicted using the MARLEY event generator with a measured Gamow-Teller strength distribution. In addition, the observed visible spectrum from charged-current scattering on ^{127}I has been measured between 10 and 55 MeV, and the exclusive zero-neutron and one-or-more-neutron emission cross sections are measured to be 5.2_{-3.1}^{+3.4}×10^{-40} and 2.2_{-0.5}^{+0.4}×10^{-40} cm^{2}, respectively.

Description of the data release 10.13139/OLCF/1969085 (https://doi.ccs.ornl.gov/ui/doi/426) from the measurements of the CsINa response to low energy nuclear recoils by the COHERENT collaboration. ...The release corresponds to the results published in "D. Akimov et al 2022 JINST 17 P10034". We share the data in the form of raw ADC waveforms, provide benchmark values, and share plots to enhance the transparency and reproducibility of our results. This document describes the contents of the data release as well as guidance on the use of the data.
Phys. Rev. Lett. 131, 221801 (2023) Using an 185-kg NaITl array, COHERENT has measured the inclusive
electron-neutrino charged-current cross section on ^{127}$I with pion
decay-at-rest neutrinos ...produced by the Spallation Neutron Source at Oak Ridge
National Laboratory. Iodine is one the heaviest targets for which low-energy
($\leq$ 50 MeV) inelastic neutrino-nucleus processes have been measured, and
this is the first measurement of its inclusive cross section. After a five-year
detector exposure, COHERENT reports a flux-averaged cross section for electron
neutrinos of $9.2^{+2.1}_{-1.8} \times 10^{-40}$ cm$^2$. This corresponds to a
value that is $\sim$41% lower than predicted using the MARLEY event generator
with a measured Gamow-Teller strength distribution. In addition, the observed
visible spectrum from charged-current scattering on $^{127}$I has been measured
between 10 and 55 MeV, and the exclusive zero-neutron and one-or-more-neutron
emission cross sections are measured to be $5.2^{+3.4}_{-3.1} \times 10^{-40}$
and $2.2^{+3.5}_{-2.2} \times 10^{-40}$ cm$^2$, respectively.
The COHERENT collaboration searched for scalar dark matter particles produced at the Spallation Neutron Source with masses between 1 and 220~MeV/c\(^2\) using a CsINa scintillation detector sensitive ...to nuclear recoils above 9~keV\(_\text{nr}\). No evidence for dark matter is found and we thus place limits on allowed parameter space. With this low-threshold detector, we are sensitive to coherent elastic scattering between dark matter and nuclei. The cross section for this process is orders of magnitude higher than for other processes historically used for accelerator-based direct-detection searches so that our small, 14.6~kg detector significantly improves on past constraints. At peak sensitivity, we reject the flux consistent with the cosmologically observed dark-matter concentration for all coupling constants \(\alpha_D<0.64\), assuming a scalar dark-matter particle. We also calculate the sensitivity of future COHERENT detectors to dark-matter signals which will ambitiously test multiple dark-matter spin scenarios.
Phys. Rev. D 108, 072001 (2023) Using neutrinos produced at the Spallation Neutron Source (SNS) at Oak Ridge
National Laboratory (ORNL), the COHERENT collaboration has studied the
Pb($\nu_e$,X$n$) ...process with a lead neutrino-induced-neutron (NIN) detector.
Data from this detector are fit jointly with previously collected COHERENT data
on this process. A combined analysis of the two datasets yields a cross section
that is $0.29^{+0.17}_{-0.16}$ times that predicted by the MARLEY event
generator using experimentally-measured Gamow-Teller strength distributions,
consistent with no NIN events at 1.8$\sigma$. This is the first inelastic
neutrino-nucleus process COHERENT has studied, among several planned exploiting
the high flux of low-energy neutrinos produced at the SNS.
We measured the cross section of coherent elastic neutrino-nucleus scattering (\cevns{}) using a CsINa scintillating crystal in a high flux of neutrinos produced at the Spallation Neutron Source ...(SNS) at Oak Ridge National Laboratory. New data collected before detector decommissioning has more than doubled the dataset since the first observation of \cevns{}, achieved with this detector. Systematic uncertainties have also been reduced with an updated quenching model, allowing for improved precision. With these analysis improvements, the COHERENT collaboration determined the cross section to be \((165^{+30}_{-25})\times10^{-40}\)~cm\(^2\), consistent with the standard model, giving the most precise measurement of \cevns{} yet. The timing structure of the neutrino beam has been exploited to compare the \cevns{} cross section from scattering of different neutrino flavors. This result places leading constraints on neutrino non-standard interactions while testing lepton flavor universality and measures the weak mixing angle as \(\sin^2\theta_{W}=0.220^{+0.028}_{-0.026}\) at \(Q^2\approx(50\text{ MeV})^2\)
