	A THz radiation source in a form of coherent radiation from short electron bunches has been constructed at the Plasma and Beam Physics (PBP) research facility, Chiang Mai University. The accelerator system consists of an RF-gun with a thermionic cathode, an alpha-magnet as a magnetic bunch compressor, and a SLAC-type linear accelerator. Coherent transition radiation emitted from short electron bunches passing through an Al-vacuum interface was used as the THz radiation source. This THz radiation can be used as a source of the THz imaging system and THz spectroscopy. Details of the accelerator system and THz radiation production will be presented. A plan for extension to accommodate Free Electron Lasers (FEL) optimized for mid-infrared and far-infrared/THz radiation will also be discussed.

	Funding: This work has been supported by the Department of Physics and Materials Science at Chiang Mai University, the Thailand Center of Excellence in Physics, and the Thailand Research Fund. A possibility to develop a compact linac-based Infrared Free-electron Laser (IR-FEL) facility has been studied at Chiang Mai University (CMU) in Thailand. Characteristics of the emitted FEL light and reliability in operation of the facility are determined by the properties of an electron injection system, an undulator, and an optical cavity. The proposed injector system for the future IR-FEL is based on the RF linear accelerator system at the Plasma and Beam Physics Research facility (PBP-linac) at CMU. However, the required electron beam properties for the IR-FEL are different from the current available electron beams from the PBP-linac. Numerical and experimental studies to modify the existing system to be able to drive the IR-FEL have been performed. The results of the studies and the proposed injector system parameters will be presented in this contribution.
