We present an exploratory study of the quasi-beam function on a $N_f = 2 + 1 + 1$ twisted mass lattice of size $24^3 \times 48$, with a pion mass of $350$ MeV and of lattice spacing $0.093$ fm. We show preliminary results for longitudinal momentum of up to $1.7$ GeV and transverse separation of up to $0.28$ fm. We also discuss the possible renormalization of the bare matrix element using RI/MOM scheme and outline the next steps in extracting the continuum TMDPDF.
