Abstract :
A lithium lens will be used to focus the 120 GeV proton beam on the antiproton production target to a spot size of about 0.1 mm, as part of the planned upgrade to the FNAL antiproton source target station. Improved focusing increases antiproton yield and corrects for possible future emittance dilution of the incident proton beam. The lens, with a radius of 3 mm and length of 8 cm, is expected to operate at a gradient of 2667 T/m and a current of 120 kA. The lens is similar in design to the antiproton collection lens
