Resumo
A boron thin ¯lm can be used for neutrons conversion and in electrically charged particles and further detection.
Since boron has a high evaporation temperature and the thickness of the boron layer needs to have few microns,
pulsed laser deposition also known as PLD can be used. When producing thin ¯lms with the PLD technique,
the target absorbs energy promoting the material ablation creating a plasma plume that deposits material
on a substrate, thus creating a thin ¯lm. Since all the deposition occurs in a vacuum chamber, the residual
heat of the plasma that condensate at the substrate can build up, thus potentially source of concern if the
substrate sensitive to temperature somehow. This work reports the analysis of the variation of temperature
in a microscope slide (substrate) as a function of the energy of femtosecond laser pulses. For measuring the
substrate temperature a type-K thermocouple was used together with associated electronics. The thermocouple
was ¯xed to the back of substrate with thermal grease for vacuum and connected to the microchip using a feed
through in the vacuum chamber. Was detected the increase of the substrate+¯lm starting at 6oC from initial
temperature (room) for the minimal laser energy 100 microjoules (25 femtoseconds).
