📋 Tender Overview
Contract awarded for Acquisition, installation, and commissioning of an electrostatic dose modulation system for a high-resolution transmission electron microscope (hrtem) for the technical research services of the university of alicante. lot-0000, title: acquisition, installation, and commissioning of an electrostatic dose modulation system for an ultra-high resolution transmission electron microscope (hrtem) for the technical research services of the university of alicante. description: the object of the contract consists of the acquisition, installation, and commissioning of an electrostatic dose modulation system for an ultra-high resolution transmission electron microscope (hrtem) for the technical research services of the university of alicante. the processing of this file is justified by the need to complete and expand the functional capabilities of the ultra-high resolution transmission electron microscope acquired by the university of alicante under the action eqc2024-008935-p, by incorporating a fully integrated and compatible electronic dose modulation system with the jeol jem-f200 transmission electron microscope in cold-feg/cfeg configuration. high-resolution transmission and scanning electron microscopy requires precise control of the electronic dose applied to the sample, especially in low-dose experiments, pulsed illumination, and the acquisition of images or analytical data under conditions where it is necessary to minimize irradiation effects without altering the optical conditions of the microscope. the system subject to the contract will allow for ultra-fast modulation, attenuation, and interruption of the electron beam through an electrostatic deflector located before the sample, enabling temporal control of the illumination and the dose applied during operation in tem and stem modes. its availability will better meet the needs of the research groups using the service, especially in work requiring precise beam control, low-dose acquisition, or pulsed illumination. estimated value excluding vat: 259998.00 eur.Acquisition, installation, and commissioning of an electrostatic dose modulation system for a high-resolution transmission electron microscope (hrtem) for the technical research services of the university of alicante.
