The purpose of the contract is to supply a laboratory cryostat for conducting tests and measurements that allows the characterization of electronic components at cryogenic temperatures before being integrated into cryogenic receptors of greater complexity. Minimum external dimensions of the dewar without the cover: 340 mm width x 340 mm depth x 115 mm high. The thickness of the bottom of the dewar will be 20 mm and that of its side walls will be 22 mm.

The system object of this contract is an instrument to maintain samples for macromolecular crystallography under cryogenic conditions, by means of a continuous laminar flow of cold gas. The system needs to be compatible with the use of nitrogen and helium gases as cryogenic gas, since the end station has been designed to allow work both in a helium environment (by means of a helium chamber) and in air. Nitrogen and helium will be input to the system as gas. The range of temperatures at sample position shall cover from 80 K to 300 K, with a high temperature stability at sample position. Achieving lower temperatures (20 K or lower) would also be beneficial for operation.

The supply requested consists of a positioning system, with a high load capacity, that allows high precision movements of an instrument in its operational spatial conditions; that is, under vacuum conditions (of the order of 10-6 mbar) and low temperature. In addition to performing the aforementioned movements with great precision and accuracy (rotations of ±20° with respect to two axes), the knowledge of the final position in which the equipment remains must be known with very low total error (minimum uncertainty), resulting It is also essential that it works correctly under vacuum conditions, that it is compatible with degassing processes (bake-out) and that it is compatible with its integration in an ISO-5 clean room. The concept of the proposed system is one of the so-called GIMBAL -from here on-, that is, based on a pivoting support that allows the rotation of an object around two orthogonal axes.

Design, manufacture of all mechanical components, integration and execution of all verifications and tests to ensure compliance with the functional requirements and specifications. The Rotary Vacuum Union is located at the top of the target axis, connecting the target to the helium inlet and outlet pipes that are fixed and It is essential to ensure that there is no refrigerant gas leakage, for this the sealing system must incorporate a helium injection system that always guarantees that the gas contained within the system cooling of the Target Station does not leak through the Union. The quality of the welds will be achive providing welding qualitication records (WPQR) in accordance with EN ISO 15614-1: 2018, welding procedure specifications (WPS) and welder performance qualification according to EN ISO 14732: 2013

The ROC is a device placed in the scattered neutron beam between the sample and the detector. It consists on an array of absorbent blades periodically spaced, which constrain the angular view of each point at the surface of detection. The blades are made of a polymeric material (PETP) coated with several layers of a neutron absorbent substance (e.g. Gd-Oxide). All those blades are under vertical stress, the aim of this is to maintain them straight and parallel among them. These blades are hold in a stiff frame screwed on a plate (trolley). The frame made of non magnetic alloy (aluminium alloy) is surrounding the blades on the sides and on the top and bottom. No pillar or stiffener is admitted in the path of the neutron beam. Moreover, those blades have to swing over certain angular amplitude delta2theta which has to be a multiple of the periodicity of the ROC. The velocity of the swing must be constant and reproducible.

The Proton Beam Window (PBW), is a component allocated in the path of the beam, and separates two atmospheres at different pressure levels. On one side of the PBW is the throttle atmosphere, with high to ultra-high vacuum levels; and on the other side, the white atmosphere, which would have a medium vacuum level. The PBW, which consists of two 1 mm thick plates, is crossed by the proton beam, which will deposit approximately 5kW in its volume. This power is evacuated by a 2mm water channel, cooled by a flow of 0.3kg water that circulates inside these plates. To ensure the required vacuum conditions on both the throttle and the blank side, the PBW must be properly sealed on both sides, ensuring that the atmospheres on each side are maintained, with a leakage rate of less than 2 - 3 · 10-5 mbars –l/a. The sealing device will be placed on both sides of the window, and fixed so that it descends attached to it. Once in position, the seal must be activated remotely, so as to guarantee the leakage rate of 2 - 3 · 10-5 mbars –l/a.
