We developed and tested a lower momentum compaction factor (low alpha) lattice at the Taiwan Photon Source (TPS). Operating in a low alpha lattice can provide picosecond bunch lengths for time-resolved research and generate coherent IR/THz synchrotron light. A bunch length of about 2.5 picosecond rms was measured by a streak camera in low alpha mode while operating in routine users mode it is as long as 10 picosecond. In this paper, we discuss related processes and measurements.
