The ALTO facility is powered by a 50 MeV/10μA linear electron accelerator dedicated to the production of radioactive beams. The production mode is based on the photo-fission process of a thick UCx target heated up to 2000°C and using the ISOL technique. For the ionization of the released fission fragments, three ion source types can be coupled to the target: Febiad ion source, surface ion source, and laser ion source. The facility can deliver the radioactive ions beams to six different experimental set-ups. The mono-charged RIB exiting from the source must be separated using a magnetic dipole in order to select a nucleus before its transmission through electrostatic devices up to the experimental set-ups. This paper is focus on the separator which was build and exploited with success since 40 years. We propose to revisit this dipole with a precise field-map calculation and particles transport simulations. These results will be use as a first brick of the understanding and reliability of the transmission along the RIB lines at the ALTO facility.

PERLE will be a unique leading edge facility designed to push advances in accelerator technology, to provide intense and highly flexible test beams for component development. In its final configuration, PERLE provides a 500 MeV elec-tron beam using high current (20 mA) acceleration during three passes through 801.6 MHz cavities. This presenta-tion outlines the technological choices, the lattice design and the main component descriptions.

Before launching the assembly of the series cryomodules, CEA developed a medium-beta cryomodule technology demonstrator in a collaboration with IPNO, LASA and ESS. This paper briefly presents the cryomodule assembly and summarizes the main results of the high RF power tests performed in 2018 in a dedicated test stand in CEA Saclay. The main ESS requirements were reached: E_{acc} = 16.7 MV/m in cavities, Pforward = 1.1 MW in power couplers, RF pulses length = 3.6 ms at 14 Hz. The piezo tuners efficiently compensated the Lorentz forces detuning and could stabilize the accelerating field better than 1% over the full length of the expected ESS 2.86 ms beam pulse without any LLRF regulation system. Following this successful validation CEA started the assembly of the first ESS medium-beta series cryomodule PB - JACoW Publishing CP - Geneva, Switzerland SP - 1940 EP - 1943 KW - cavity KW - cryomodule KW - cryogenics KW - linac KW - status DA - 2019/06 PY - 2019 SN - 978-3-95450-208-0 DO - DOI: 10.18429/JACoW-IPAC2019-TUPTS006 UR - http://jacow.org/ipac2019/papers/tupts006.pdf ER - TY - CONF AU - Kraft, H.

This project aims at exploring the transmutation of long-lived nuclear wastes. A first phase is planned to validate the reliability of a 100 MeV/4 mA Protons LINAC carrying the beam toward an ISOL facility, prefiguring the real MYRRHA demonstrator at 600 MeV. This project is called MINERVA. This paper presents the status of the beam dynamic studies for the high energy beam transport lines at 100 MeV. In agreement with the project require-ments, we describe the specificities of these beam lines for which it is needed to implement a fast kicker-septum. This system will separate the beam between two main lines: toward the beam dump or the ISOL facility. We also describe the studies on the Beam Position Monitor (BPM) selected for MYRRHA. Part of this work was sup-port by the MYRTE project of the European Union.

In this paper we will report the optics design and beam dynamics simulations for the beam line dedicated to subatomic physics, more specifically for the measurement of the proton radius. This measurement requires extremely low energy spread (5×10−4) and small beam sizes with low divergence at three beam energies: 30, 50 and 70 MeV. The beam line includes a D-type chicane coupled to a dechirping passive structure, which generates inductive wakefields in order to get the performances required for such measurement.
