Abstract :
A 4-rod-RFQ (radio-frequency quadrupole) has been built for the deceleration of antiprotons which will be extracted from LEAR at 2.0 MeV and injected at 0.2 MeV into the RF-mass spectrometer built by CSNSM, Orsay, for the high-precision mass comparison of protons and antiprotons (PS189). The properties of the RFQ system, which should improve the counting rate by a factor of up to 10/sup 3/, and the status of the project are reported.<>
