Joaquin PortillaAn experimental study of amplitude modulation (AM) and phase modulation (PM) noise spectra in cascaded amplifiers was carried out as a function of the number of amplification stages and the input power. Flicker and white noise contributions were determined, as well as effective noise figure (NF) from AM and PM noise spectra from small-signal to large-signal regimes. Simultaneous measurements of AM and PM noise were performed, and associated correlation was measured as a function of the offset frequency from the carrier. Measurements exhibited, in general, quite low AM–PM correlation levels both in the flicker and white noise parts of the spectrum. In some particular amplifier configurations, however, measurements showed some peaks in the correlation at some specific input power levels in the transition zone, from a quasi-linear to strong compression. The results show that the effective noise figure decreases with the number of stages for a given carrier output power level.

A new compact linear proton accelerator project (named LINAC 7) for multiple low-current applications, designed and built in-house at the Beam Laboratory of the University of the Basque Country (UPV/EHU) is described. The project combines the University, a research technology center and a private company with the aim of designing and building a compact, low-current proton accelerator capable of accelerating particles up to 7 MeV. In this paper, we present an overview of the accelerator design, summarize the progress and testing of the components that have been built, and describe the components that are being designed that will allow us to achieve the final desired energy of 7 MeV.

Large scientific projects present new technological challenges, such as the distributed control over a communication network. In particular, the middleware Experimental Physics and Industrial Control System (EPICS) is the most extended communication standard in particle accelerators. The integration of modern control architectures in these EPICS networks is becoming common, as for example for the PXI/PXIe and xTCA hardware alternatives. In this paper, a different integration procedure for PXI/PXIe real-time controllers from National Instruments is proposed, using LabVIEW as the design tool. This methodology is considered and its performance is analyzed by means of a set of laboratory experiments. This control architecture is proposed for achieving the implementation requirements of fast controllers, which need an important amount of computational power and signal processing capability, with a tight real-time demand. The present paper studies the advantages and drawbacks of this methodology and presents its comprehensive evaluation by means of a laboratory test bench, designed for the application of systematic tests. These tests compare the proposed fast controller performance with a similar system implemented using an standard EPICS IOC provided by the CODAC system.

The baseline design for the ESS-Bilbao light-ion linear accelerator and neutron source has been completed and the normal conducting section of the linac is at present under construction. The machine has been designed to be compliant with ESS specifications following the international guidelines of such project as described in Ref. [1]. The new accelerator facility in Bilbao will serve as a base for support of activities on accelerator physics carried out in Spain and southern Europe in the frame of different ongoing international collaborations. Also, a number of applications have been envisaged in the new Bilbao facility for the outgoing light ion beams as well as from fast neutrons produced by low-energy neutroncapture targets, which are briefly described.

Inari Badillo Fernández is a lecturer at the Department of Electricity and Electronics of the University of the Basque Country. Electronic engineer since 2009, master degree in Advanced Electronic Systems (2011) and PhD in Electronic Engineering at the University of the Basque Country (2015).
His research work has been mainly devoted to the development of technology applied to particle accelerators, beginning with the PhD thesis “Advanced Techniques for Diagnostics and Control Applied to Particle Accelerators” to the present, working at the LINAC7 project at the IZPIlab laboratory in control related tasks.
In the area of distributed control, he has taken part in several collaboration projects with some of the main laboratories in the field of particle accelerators such as the Rutherford Appleton Laboratory (United Kingdom) or the Helmholtz-Zentrum Berlin für Materialien und Energie GmbH (Germany). In them, he has been involved in the design and development of several devices. He has also worked in collaboration with GMV company and CIEMAT in the development of particle accelerator technology oriented to fusion in IFMIF-DONES and IFMIF-EVEDA. In the last mentioned, he tested and validated in-situ several tools developed for the facility.
This research work has resulted in several journal and conference articles.
