Abstract	The facility for experimental investigation of a copper cavity lifetime under multiple action of 30 GHz microwave power pulses is created now by the collaboration of CLIC (CERN), JINR (Dubna) and IAP RAS (Nizhny Novgorod). A design of the test cavity, an estimation of the operating parameters of the FEM oscillator and the RF power transmission line was already discussed at FEL'2003. Last year was devoted to the achievement of the design parameters of all of the elements of the facility. We have developed the equipment and the procedure of RF transmission line adjustment, improved the stability of the linac power supplies, created the new system of data acquisition. Effect of central mode splitting in Bragg resonators is one of the problems under study. Start of the full-scale experiments is planned to the end of 2004.
