	This paper presents measurements of the beam transmission performed on the 4-rods RFQ currently under operation at Fermilab. The beam current has been measured at the RFQ exit as a function of the magnetic field strength in the 2 LEBT solenoids. This measurement is compared with a scan performed on the Fermi Grid with the beam dynamics code TRACK. A particular attention is given to the impact, on the RFQ beam transmission, of the space-charge neutralization in the LEBT and of the field asymmetry on the 4-rods RFQ.
