LISA Pathfinder: Optical Metrology System monitoring during operations

The LISA Pathfinder (LPF) mission has demonstrated excellent performance. In addition to having surpassed the main mission goals, data has been collected from the various subsystems throughout the duration of the mission. This data is a valuable resource, both for a more complete understanding of the LPF satellite and the differential acceleration measurements, as well as for the design of the future Laser Interferometer Space Antenna (LISA) mission. Initial analysis of the Optical Metrology System (OMS) data was performed as part of daily system monitoring, and more in-depth analyses are ongoing. This contribution presents an overview of these activities along with an introduction to the OMS. © Published under licence by IOP Publishing Ltd.ESA/22331/09/NL/HBESA/16238/10/NL/HBDLRBundesministerium für Wirtschaft und EnergieDFG/EXC/QUES

LISA Pathfinder: OPD loop characterisation

The optical metrology system (OMS) of the LISA Pathfinder mission is measuring the distance between two free-floating test masses with unprecedented precision. One of the four OMS heterodyne interferometers reads out the phase difference between the reference and the measurement laser beam. This phase from the reference interferometer is common to all other longitudinal interferometer read outs and therefore subtracted. In addition, the phase is fed back via the digital optical pathlength difference (OPD) control loop to keep it close to zero. Here, we analyse the loop parameters and compare them to on-ground measurement results.DLRFederal Ministry for Economic Affairs and Energ

Assessment of Youth-Friendly Postabortion Care Services: A Global Tool for Assessing and Improving Postabortion Care for Youth

This tool is designed to help assessment teams, project managers, supervisors, and providers collect detailed information on the quality of Postabortion Care (PAC) services provided to adolescents at a given facility in order to make services more youth-friendly. It can also be used before PAC services have been established to see how best to design PAC services to meet youth’s needs. The assessment process facilitates the development of action plans for quality improvement that can help facilities address policy, operations, training, and other program areas needing adjustments and change. The tool also provides essential baseline information, allowing for repeated applications to measure changes and the impact of program interventions. Although the tool is primarily for use by a team, it may also be used by an individual

LISA Pathfinder: First steps to observing gravitational waves from space

LISA Pathfinder, the European Space Agency's technology demonstrator mission for future spaceborne gravitational wave observatories, was launched on 3 December 2015, from the European space port of Kourou, French Guiana. After a short duration transfer to the final science orbit, the mission has been gathering science data since. This data has allowed the science community to validate the critical technologies and measurement principle for low frequency gravitational wave detection and thereby confirming the readiness to start the next generation gravitational wave observatories, such as LISA. This paper will briefly describe the mission, followed by a description of the science operations highlighting the performance achieved. Details of the various experiments performed during the nominal science operations phase can be found in accompanying papers in this volume

LISA Pathfinder closed-loop analysis: a model breakdown of the in-loop observables

This paper describes a methodology to analyze, in the frequency domain, the steady-state control performances of the LISA Pathfinder mission. In particular, it provides a technical framework to give a comprehensive understanding of the spectra of all the degrees of freedom by breaking them down into their various physical origins, hence bringing out the major contributions of the control residuals. A reconstruction of the measured in-loop output, extracted from a model of the closed-loop system, is shown as an instance to illustrate the potential of such a model breakdown of the data

Listening to women: relational approaches to female offender management

Purpose: To explore women’s experiences of criminal justice systems to inform the development of guidance on working with women.Design/methodology/approach: A two-part, independent samples, qualitative study utilising semi-structured interviews incorporating both IPA and Thematic Analysis was conducted. In study 1, semi-structured interviews were conducted with six women on probation in the community and data were analysed using Interpretative Phenomenological Analysis. Interviews in study 2 were conducted with seven women in custody with data analysed using inductive-deductive thematic analysis. The applicability and expansion of study 1 themes was then explored.Findings: Seven emergent themes indicated relational approaches to offender management may improve experiences of judicial systems for female offenders and for their probation officers. This approach may help prevent common systemic issues from perpetuating negative interactions between these groups. Specific suggestions for developing relational security and consistency of care within these relationships are provided. Practical implications: Taking a relational approach to female offender management may help remedy some of the systemic difficulties faced by female offenders and their probation officers. Originality: By focussing on the experiences of women screened in to the Offender Personality Disorder Pathway this study provides insight as to how this service can assist in the development of relational security between probation staff and their clients
