| Description
| - The COMPASS tokamak, recently transferred from UKAEA Culham to IPP Prague, is equipped with a set of saddle coils for producing controlled resonant magnetic perturbations (RMPs). In the future experimental programme of COMPASS we plan to focus on studies of RMPs, especially in view of their application as an ELM control mechanism and their planned use in ITER. In the present contribution we describe the preparatory calculations for the planned experiments. We computed the spectra of perturbations for several different equilibra predicted by MHD simulations and determined the positions and sizes of the resulting islands. It is shown how the saddle coils of COMPASS can be adapted to our equilibria to obtain good island overlap at the edge, which is believed to be a key component in the ELM mitigation effect. The techniques used for adapting the coils to achieve this result are described. Those are fairly general and could be used in the design of RMP coils on other machines.

- Tokamak COMPASS, nedávno přenesený z UKAEA Culham do ÚFP AV, je vybaven sadou sedlových cívek pro vytváření rezonantních magnetických perturbací (RMP). V budoucím experimentálním programu COMPASSu se plánujeme soustředit na studie RMP, zejména vzhledem k jejich využití jako mechanismu kontroly ELMů (edge localized modes) a jejich plánovanému použití v ITERu. V tomto příspěvku popisujeme přípravné výpočty pro plánované experimenty. Spočítali jsme spektra perturbací pro různé magnetické rovnováhy předpovězené MHD simulacemi a určili jsme polohy a rozměry výsledných magnetických ostrovů. Je ukázáno jak mohou být sedlové cívky na COMPASSu přizpůsobeny na naše rovnováhy za účelem dosažení dostatečného překryvu ostrovů na okraji, což je pokládáno za klíčovou součást efektu zmírnění ELMů. Jsou popsány techniky použité pro přizpůsobení cívek za účelem dosažení tohoto výsledku. Tyto techniky jsou poměrně obecné a mohly by být použity pro návrh RMP cívek na jiných zařízeních. (cs)
