A pulsed magnet is used to kick single electron bunches into the SLAC A-line from the 120 Hz LCLS-1 bunch train. These single bunches are transported to the End Station Test Beam facility. It is mandated that extraction from the LCLS beam does not disturb the non-kicked pulses. An 8.7 mrad kick is required to extract a bunch; without compensation the following bunch experiences a 3 m kick; with compensation this kick is reduced to less than 0.1 m which is well within the jitter level of about 0.2 m. Electron and photon diagnostics were used to identify problems arising from eddy currents, beam feedback errors, and inadequate monitoring and control protocol. This paper discusses the efforts to diagnose, remedy, and control the pulse snatching. Show Partial Abstract
