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