The LIPAc accelerator will be a linear CW deuteron accelerator capable of delivering a 9 MeV, 125 mA beam which aims to validate the technology that will be used in the future high power accelerator-driven neutron source, IFMIF. In summer 2017 a campaign of measurements was done during the injector commissioning, in which a Fluorescence Profile Monitor based on an Intensified CID camera (ICID) was used to measure the beam transverse profile at the extraction of the ion source. In this contribution we review the design of the ICID, its performance and discuss the measurements carried out. The performance of ICID monitors for its use in future accelerators will be assessed.
The design and procurement of 98 Intersection Control Racks is part of the Spanish in-kind contribution to the European XFEL. This cabinet contains all the necessary electronics to control both the phase shifter and the quadrupole magnet positioning table that belong to the intersections of the undulator segments. A closed-loop control system has been developed, achieving a repeatability of less than 10 μm and 1 μm, respectively. Special care has been taken to get a repeatable design that minimizes electromagnetic noise and interference. Extensive tests have been conceived and applied to ensure reliable industrial production and quality assessment. Validation tests have been automated, facilitating the identification of defective components and unusual situations during serial production. This paper describes the Intersection Control Rack hardware and software, the design process, the quality assurance system and the main technical difficulties arisen at every design phase.
The LIPAc accelerator [1] will be a 9 MeV, 125 mA CW deuteron accelerator which aims to validate the technology that will be used in the future IFMIF accelerator. Several types of Beam Position Monitors -BPM’sare placed in each section of the accelerator to ensure a good beam transport and minimize beam losses. Prototypes of almost all the BPM’s have been already fabricated. Acceptance tests have been carried out on each device. The output of the vacuum leak tests and electrical tests will be analyzed in this contribution. In addition, the test bench to characterize the BPM’s has been upgraded and validated using some prototypes in order to obtain a better global measurement accuracy of the electrical center offset. The test bench can be used to crosscheck the simulations with the real response of each BPM. The result of the comparison will be discussed in detail.
The AMIT cyclotron will be a 8.5 MeV, 10 A CW H accelerator which aims to deliver a beam for radioisotope production. In order to properly validate all the beam commissioning steps, a set of diagnostics needs to be implemented. They must cover all the commissioning phases: ion source characterization, medium energy acceleration and nominal energy at full current. Due to compactness of the design, the number of beam diagnostics is limited and restricted to the most essential ones during operation. An overview of the diagnostics that are planned for the characterization of the cyclotron will be discussed in this contribution. In all the commissioning phases, beam current probes are essential to validate the cyclotron and each subsystem. As a main diagnostic, a movable probe has been designed and simulated for optimization of the cyclotron. The thermal simulations of the probe and the mechanical integration are presented.
