MINERVA is a new X-ray facility under construction at the ALBA synchrotron specially designed to support the development of the ATHENA (Advanced Telescope for High Energy Astrophysics) mission. The beamline design is originally based on the monochromatic pencil beam XPBF 2.0 from the Physikalisch-Technische Bundesanstalt (PTB), at BESSY II already in use at this effect. MINERVA will host the necessary metrology equipment to integrate the stacks produced by the cosine company in a mirror module (MM) and characterize their optical performances. From the opto-mechanical point of view, the beamline is made up of three main subsystems. First of all, a water-cooled multilayer toroidal mirror based on a high precision mechanical goniometer, then a sample manipulator constituted by a combination of linear stages and in-vacuum hexapod and finally an X-ray detector which trajectory follows a cylinder of about 12 m radius away from the MM. MINERVA is funded by the European Space Agency (ESA) and the Spanish Ministry of Science and Innovation. MINERVA is today under construction and will be completed to operate in 2022., Proceedings of the 11th Mechanical Engineering Design of Synchrotron Radiation Equipment and Instrumentation, MEDSI2020, Chicago, IL, USA

During the ALBA design phase, the protein macromolecular protein crystallography beamline, XALOC, required several in-house developments. The major part of these designs was at the end station where the necessity of customization is always much higher. The most relevant of these instruments was the beam conditioning elements table [1]. This accurate stage, which supports the diffractometer as well, includes the four movements required to align the components to the nominal beam as well as position the diffractometer. This design compacts, especially the vertical and pitch movements, both in a single stage, with a couple of stages for all four excursions. The solution maximise the stiffness and preserves at the same time the resolution close to 0.1��m while being able to withstand a half tone of payload. Thanks this compactness and performances this design concept, the vertical and pitch combined stage, was not only applied at XALOC for its diffractometer and detector table, but it has been widely adapted at several ALBA beamlines: at NCD-SWEET [2] as a detector table, a beam conditioning elements table [3] and sample table, at MSPD beamline as the KB table, at NOTOS beamline as metrology table, and also at the new ESA MINERVA beamline [4] for their sample mirror modules positioning. Beamlines have not been the only beneficiaries of this design, also different kind of instrumentation like an hall probe measuring bench [5], and even a stitching platform for the ALBA optics laboratory [6]. Moreover, the concept has outreach ALBA and has been adopted also at other facilities worldwide, synchrotrons and also scientific instrumentation suppliers around Europe. This poster presents most of the applications of the skin concept and their variations and main measured performances., Proceedings of the 11th Mechanical Engineering Design of Synchrotron Radiation Equipment and Instrumentation, MEDSI2020, Chicago, IL, USA

A new 6-DOF sample manipulator has been designed for the ALBA Synchrotron PhotoEmission Electron Microscopy (PEEM) experimental station, based on a commercial Elmitec LEEM 3. The new design includes full motorization of all 6 axes with position feedback, no backlash, and maximized stability, crucial to achieve the best spatial resolution of down to 8 nm (in so-called LEEM mode). The in-plane longitudinal and transversal motions with sub-micron resolution are based on high precision linear guides, while the pitch and roll stages (sample tilt), guided by angular guides, are actuated by a double-flexure system, which enhances the overall rigidity of the system. The vertical stage is composed by a high rigidity recirculating roller screw and cross roller guides. Finally, 360° yaw rotation is supplied by a differentially pumped commercial rotary stage. On top of the stage, the sample support is mounted on a customized DN63CF flange. This support keeps the original functionalities of the sample manipulator and holders, with 6 independent electrical contacts, and the possibility to heat the sample up to 2000 K and cool it to 100 K with an improved liquid nitrogen cooling system., Proceedings of the Mechanical Eng.~Design of Synchrotron Radiation Equipment and Instrumentation, MEDSI2018, Paris, France

In the recent years, the number of high power lasers devoted to particle acceleration has increased in Europe. Additionally to this, some synchrotrons and accelerators are integrating these lasers in its lines, increasing the scientific synergies. The HP laser must be transported in HV. The use of HV also permits good cleanliness in the optical set up. As addition, is necessary to create an adaptable and modular design where several chambers could be assembled together. One additional constrain is the stability. A new model of HV chambers is presented. These consist in a frame where the walls are exchangeable panels, which make easier the introduction of a new configuration of ports. The system was designed as construction blocks. For a proper connection of the chambers a new interior fixation and pushers system was designed. Thanks to this, coupling new HV chambers, the volume total can be also easily modified. Finally, a third generation decoupled system is integrated inside, consisting of a stable breadboard, this supported by six columns that implement a preloaded kinematical mount, providing both an outstanding stability and a fine regulation (1st RM: 77Hz)., Proceedings of the 9th Edition of the Mechanical Engineering Design of Synchrotron Radiation Equipment and Instrumentation Conference, MEDSI2016, Barcelona, Spain

This paper reports design, modelling, simulation and optimization results for the ALBA MIRAS infrared radiation extraction mirror. Finite element analysis (FEA) was used to simulate the thermal mechanical behaviour of the device. With the aim to ensure a good thermal performance, conservative assumptions were applied: all of the incident Bending Magnet (BM) radiation is absorbed at the mirror surface, constant bending magnetic field and low thermal contact between the mirror Al 6061 and the OFHC copper arm. A novel solution has been implemented in order to provide an effective cooling by a natural convection on the in-air part of extraction mirror assembly. This has voided the necessity for a water cooling that often causes problems due to the associated vibrations. The power conditions were calculated by using SynRad+. The main ALBA Storage Ring design parameters are: 3 GeV, 400 mA and 1.42 T. According to these conditions, the mirror absorbs 15 W with a peak power density of 0.51 W/mm2. The peak temperature calculated was 63.2 °C. The real measurements reported during the commissioning stage showed a good thermal performance, in agreement with the results predicted by FEA., Proceedings of the 9th Edition of the Mechanical Engineering Design of Synchrotron Radiation Equipment and Instrumentation Conference, MEDSI2016, Barcelona, Spain

Analizamos 23 parámetros de control, en 632 máquinas de ordeño y su relación con la calidad de la leche. Tomando la pezonera como punto de unión entre máquina - vaca se realizaron ensayos sobre dos juegos de pezoneras, se tomaron mediciones del touch point pressure difference (TPPD), pulsación, vacíos de ordeño, muestras bacteriológicas en el interior de las pezoneras así como análisis de microscopía de escáner electrónico. Finalmente tomando como referencia una ganadería “tipo” con 60 vacas en ordeño se estudiaron entre las diferentes posibilidades que nos podemos encontrar en el mercado (sala o robot de ordeño) los principales condicionantes a la hora de decidir; inversión inicial, mano de obra, producción, consumo energético, alimentación o calidad de vida. Los resultados del estudio muestran que la calidad de la leche guarda relación con el tipo de instalación, coincidiendo la mejor calidad con las instalaciones con mejor puesta a punto, 88% en salas de ordeño, 86% en circuitos y 82% en las cántaras. El deterioro de las pezoneras en sistemas de ordeño robotizado (SOR) y la necesidad de reemplazo están más condicionados por la carga bacteriana que por los desfases o retardos en la respuesta mecánica. Desde el punto de vista de la selección entre diferentes alternativas en explotaciones de carácter familiar y tamaño medio (60 vacas en ordeño) podemos concluir que la inversión inicial más económica es poner una sala de ordeño (2 x 6) equiparable en tecnificación y rendimiento a un SOR. Si imputamos la mano de obra, en SOR se ordeñan 13 y 5,8 veces más de kg/h que en sala con 3 y 2 ordeños respectivamente. El índice de calidad de vida calculado en función de 10 variables fue en SOR 2,5 y 4 veces mayor que ordeñando 2 y 3 veces al día. El coste energético es mayor en SOR con respecto a dos ordeños y la mejor eficiencia de alimentación se consigue en el caso de 2 ordeños, seguido de SOR y de 3 ordeños en sala. La producción anual se maximiza con 3 ordeños en sala pero el beneficio neto máximo se consigue en SOR.
