    SOXS (Son Of X-Shooter) is a unique spectroscopic facility that will operate at the ESO New Technology Telescope (NTT) in La Silla from 2021 onward. The spectrograph will be able to cover simultaneously the UV-VIS and NIR bands exploiting two different arms and a Common Path feeding system. We present the design of the SOXS instrument control electronics. The electronics controls all the movements, alarms, cabinet temperatures, and electric interlocks of the instrument. We describe the main design concept. We decided to follow the ESO electronic design guidelines to minimize project time and risks and to simplify system maintenance. The design envisages Commercial Off-The-Shelf (COTS) industrial components (e.g. Beckhoff PLC and EtherCAT fieldbus modules) to obtain a modular design and to increase the overall reliability and maintainability. Preassembled industrial motorized stages are adopted allowing for high precision assembly standards and a high reliability. The electronics is kept off-board whenever possible to reduce thermal issues and instrument weight and to increase the accessibility for maintenance purpose. The instrument project went through the Preliminary Design Review in 2017 and is currently in Final Design Phase (with FDR in July 2018). This paper outlines the status of the work and is part of a series of contributions describing the SO

    (SPIE, 2018-06) Brucalassi, A.; Araiza-Durán, J.A.; Pignata, G.; Campana, S.; Claudi, R.; Schipani, P.; Aliverti, M.; Baruffolo, A.; Ben-Ami, S.; Biondi, F.; Capasso, G.; Cosentino, R.; D'Alessio, F.; D'Avanzo, P.; Gardiol, D.; Hershko, O.; Kuncarayakti, H.; Munari, M.; Ricci, D.; Riva, M.; Rubin, A.; Zanmar Sanchez, R.; Scuderi, S.; Vitali, F.; Achrén, J.; Arcavi, I.; Bianco, A.; Cappellaro, E.; Colapietro, M.; Della Valle, M.; Diner, O.; D'Orsi, S.; Fantinel, D.; Fynbo, J.; Gal-Yam, A.; Genoni, M.; Hirvonen, M.; Kotilainen, J.; Kumar, T.; Landoni, M.; Lehti, J.; Li Causi, G.; Loreggia, D.; Marafatto, L.; Mattila, S.; Pariani, G.; Rappaport, M.; Salasnich, B.; Smartt, S.; Turatto, M.
    SOXS (Son of X-Shooter) will be the new medium resolution (R∼4500 for a 1 arcsec slit), high-efficiency, wide band spectrograph for the ESO-NTT telescope on La Silla. It will be able to cover simultaneously optical and NIR bands (350-2000nm) using two different arms and a pre-slit Common Path feeding system. SOXS will provide an unique facility to follow up any kind of transient event with the best possible response time in addition to high efficiency and availability. Furthermore, a Calibration Unit and an Acquisition Camera System with all the necessary relay optics will be connected to the Common Path sub-system. The Acquisition Camera, working in optical regime, will be primarily focused on target acquisition and secondary guiding, but will also provide an imaging mode for scientific photometry. In this work we give an overview of the Acquisition Camera System for SOXS with all the different functionalities. The optical and mechanical design of the system are also presented together with the preliminary performances in terms of optical quality, throughput, magnitude limits and photometric properties. © 2018 SPIE.

    Son Of X-Shooter (SOXS) is the new instrument for the ESO 3.5 m New Technology Telescope (NTT) in La Silla site (Chile) devised for the spectroscopic follow-up of transient sources. SOXS is composed by two medium resolution spectrographs able to cover the 350-2000 nm interval. An Acquisition Camera will provide a light imaging capability in the visible band. We present the procedure foreseen for the Assembly, Integration and Test activities (AIT) of SOXS that will be carried out at sub-systems level at various consortium partner premises and at system level both in Europe and Chile. © 2018 SPIE.

    The common path of SOXS (Son of X-Shooter)
    (SPIE, 2018-06) Claudi, R.; Aliverti, M.; Biondi, F.; Munari, M.; Zanmar Sanchez, R.; Campana, S.; Schipani, P.; Baruffolo, A.; Ben-Ami, S.; Brucalassi, A.; Capasso, G.; Cosentino, R.; D'Alessio, F.; D'Avanzo, P.; Hershko, O.; Kuncarayakti, H.; Rubin, A.; Scuderi, S.; Vitali, F.; Achrén, J.; Araiza-Durán, J.A.; Arcavi, I.; Bianco, A.; Cappellaro, E.; Colapietro, M.; Della Valle, M.; Diner, O.; D'Orsi, S.; Fantinel, D.; Fynbo, J.; Gal-Yam, A.; Genoni, M.; Hirvonen, M.; Kotilainen, J.; Kumar, T.; Landoni, M.; Lehti, J.; Li Causi, G.; Marafatto, L.; Mattila, S.; Pariani, G.; Pignata, G.; Rappaport, M.; Ricci, D.; Riva, M.; Salasnich, B.; Smartt, S.; Turatto, M.
    Son of X-Shooter (SOXS) will be a high-efficiency spectrograph with a mean Resolution-Slit product of 4500 (goal 5000) over the entire band capable of simultaneously observing the complete spectral range 350-2000 nm. It consists of three scientific arms (the UV-VIS Spectrograph, the NIR Spectrograph and the Acquisition Camera) connected by the Common Path system to the NTT and the Calibration Unit. The Common Path is the backbone of the instrument and the interface to the NTT Nasmyth focus flange. The light coming from the focus of the telescope is split by the common path optics into the two different optical paths in order to feed the two spectrographs and the acquisition camera. The instrument project went through the Preliminary Design Review in 2017 and is currently in Final Design Phase (with FDR in July 2018). This paper outlines the status of the Common Path system and is accompanied by a series of contributions describing the SOXS design and properties after the instrument Preliminary Design Review. © 2018 SPIE.

    SOXS (Son of X-shooter) is a wide band, medium resolution spectrograph for the ESO NTT with a first light expected in early 2021. The instrument will be composed by five semi-independent subsystems: a pre-slit Common Path (CP), an Acquisition Camera (AC), a Calibration Unit (CU), the NIR spectrograph, and the UV-VIS spectrograph. In this paper, we present the mechanical design of the subsystems, the kinematic mounts developed to simplify the final integration procedure and the maintenance. The concept of the CP and NIR optomechanical mounts developed for a simple pre- alignment procedure and for the thermal compensation of reflective and refractive elements will be shown. © 2018 SPIE.
