	Funding: Work partially supported by the Spanish Government (MINECO-CDTI) under program FEDER INTERCONNECTA. The 72.75 MHz LINCE RFQ is designed to function at room temperature. Effective operation of the RFQ cavity requires efficient water cooling in order to dissipate significant resistive power non-uniformly distributed on the copper walls and vanes. This amounts to about 10 kWfor one 0.5m long RFQ section. Cylindrical cooling channels have been designed and optimized by varying their diameter and position in order to minimize the frequency shift generated by thermal displacements. The article reports results of power loss simulations coupled with electromagnetic modelling studies and their consequences on the RFQ performance in terms of resonant frequency and thermal deformations.

	Funding: Work partially supported by the Spanish Government (MINECO-CDTI) under program FEDER INTERCONNECTA The low-energy part of the LINCE facility can be based on a 72.75MHz normal-conducting RFQ designed to give a 450 keV/u boost for A/Q=7 ions in about 5m length. The vanes have been electromagnetically designed to accommodate dedicated RF windows producing effective separation of the RFQ modes in an octagonal-shaped resonance chamber. This article outlines the optimization of the quality factor of the cavity by using numerical methods for electromagnetic calculations.
