	abstract = {<p>High secondary emission yield (SEY), and the subse- quent build-up of a secondary electron cloud, may se- verely limit the stability of high-intensity particle beams inside particle accelerators. One of the best candidates of beam pipe coating for reduced SEY has been amorphous carbon (a-C) produced by direct current (D.C.) magne- tron sputtering. Here we used pulsed laser deposition (PLD), to prepare a-C films from a pure carbon target at substrate temperatures ranging from 300 K to 773 K. The ablating laser was a Nd:YAG system operating at 1064 nm wavelength. With increasing temperature the optical band gap dropped from about 2.1 eV to 1.0 eV. This trend indicates transition from predominantly a-C films to films with more graphitic content, which was also con- firmed by Raman measurements. SEY spectra were taken upto 1732 eV of primary electron energy. The maximum SEY value decreased from 1.9 in a-C films down to 1.4 in highly graphitic films deposited at higher temperatures</p>
