A high frequency, large amplitude helium filled RFQ (Radio Frequency Quadrupole) beam cooler and buncher was developed and tested for use in the TITAN (TRIUMF's Ion Trap for Atomic and Nuclear science) Penning trap mass spectrometer facility. This device will cool and bunch radioactive ion beams for use in TITAN's high precision mass measurements of short-lived isotopes and other experiments. A test stand was built to test the transmission and properties of ions from a surface ion source through injection optics, the linear Paul trap RFQ and the extraction optics in both continuous and pulsed modes. The efficiency of the device was determined to be on the order of 60% in continuous mode. The present measurements confirm a transverse emittance of the extracted beam in bunched mode operation of 4 pi-mm-mrad at an extraction energy of 4 keV.
