In science:

To quantify this latter source of polarisation loss, a realistic simulation of depolarisation and spin precession in the BDS is presented. A realistic bunch train is generated by using PLACET to track bunches through a misaligned linac in which a 1:1 correction and dispersion free steering is made.
Precision Polarimetry at the ILC: Concepts, Simulations and experiments
Figure 1 illustrates the luminosity degradation due to collimation wakefield effects for both the ILC and CLIC, based on simulations using the codes PLACET and GUINEAPIG , and assuming nominal parameters.
Proposal for Single-Bunch Collimator Wakefield Measurements at SLAC ESTB
For the particular collimator geometry considered in this section, the geometric kick factor as a function of the collimator half gap is shown in Fig. 15 (bottom), comparing the PLACET simulation results with the analytical calculation for the diffractive regime.
Proposal for Single-Bunch Collimator Wakefield Measurements at SLAC ESTB
These results have been obtained from beam tracking simulations using the code PLACET.
