  We simulate the capture process of MgF molecules into a frequency-chirped
molecular MOT. Our calculations show that by chirping the frequency, the MOT
capture velocity is increased by about of factor of 4 to 80 m/s, allowing for
direct loading from a two-stage cryogenic buffer gas beam source. Moreover, we
simulate the effect of this frequency chirp for molecules already present in
the MOT. We find that the MOT should be stable with little to no molecule loss.
The chirped MOT should thus allow loading of multiple molecule pulses to
increase the number of trapped molecules
