TI - Multiharmonic Buncher for the Isolde Superconducting Recoil Separator Project J2 - Proc. of HB2023, Geneva, Switzerland, 09-13 October 2023 CY - Geneva, Switzerland T2 - ICFA Advanced Beam Dynamics Workshop on High-Intensity and High-Brightness Hadron Beams T3 - 68 LA - english AB - The ISOLDE Superconducting Recoil Separator (ISRS) is a proposal of building a very compact separator ring as an instrument in the HIE-ISOLDE facility. The injection of the HIE-ISOLDE beam into this ring requires a more compact bunch structure, so a Multi-Harmonic Buncher device is proposed for this task. The MHB will operate at a frequency of 10.128 MHz, which is a 10\% of the linac frequency, and would be installed before the RFQ. The MHB is desgined as a two electrodes system, and the MHB signal, composed for the first four harmonics of the fundamental frequency, is fed into the electrodes that are connected to the central conductor of a coaxial waveguides. The full design of the MHB is presented, including electromagnetic optimization of the electrode shape, optimization of the weights of each of the harmonic contribution, mechanical and thermal design of the structure. The RF generation and electronics to power up the device are also presented. A solution that generates directly the composed signal andis then amplified by a solid state power amplifier is also presented in this contribution.
