Information On E-Beam Evaporation Systems

The physical vapor deposition or PVD is a method where there will be an extreme, electron beam is generated from a filament and navigated via electric and magnetic fields to strike source material, for example is pellets of Au, then vanish it within a vacuum environment is called E-Beam evaporation. There is some point where as the source material is heated by the energy transfer to the surface atoms that will have enough energy to leave the surface.  It will traverse the vacuum chamber, at thermal energy not less than 1 eV and can be used to coat a substrate placed above the vaporizing material. 300 mm to 1 meter is the average working distances.

evaporationThe chamber pressure must be below the point as the thermal energy is low.  This is by means of free path is longer than the expanse between the electron beam source and the substrate. The average distance of an atom or molecule can transport in a vacuum chamber is called the free path. This is typically around 3.0 x 10-4 Torr or lower. It materializes before it bumps into the other particle therefore disturbing its course to some degree.

First and foremost, the information on e-beam evaporation systems purpose is to run an e-beam evaporation process at the elevated end of the pressure array to allow a wide beam ion beam source to be employed at the same time for film densification or other property adjustment. The evaporation without ion beam assist can be done at any pressure below. Although the process will always be to increases the pressure due to outgassing of materials within the vacuum chamber.

There are electron e-beam evaporation sources. These are the Single Pocket, Rotary Pocket and Linear Pocket. For more information regarding e-beam evaporation systems, visit this this here www.angstromengineering.com.

How Our Brain Processes Music

brain

It’s so interesting to see how our brain reacts to music and how music affects us. Music can be a passion and distraction at the same time. Here’s a couple of surprising facts behind the science of music.

Music that is happy or sad can affect how we feel about faces. After listening to happy or sad music, our brain inherently sees a neutral face as either more happy or more sad. This face would have a neutral expression, but for some reason our brain interprets it accordingly to the music that is being played.

Moderate sound level music playing in the background may increase our creativity. However, high sound level music can distract us from our work flow. So the next time you need to be creative, put on some ambient music in the background.

This next one might not be as surprising. The music we prefer to listen to can predict our personality. People who like to listen to classical music are more creative and have higher self-esteem. People who like rap music have high self-esteem and are outgoing. Dance music enthusiasts are outgoing and creative. The list goes on and on, but you get the jist.

So yes, music does affect our brain and the way we think from time to time. With more studies, we will be sure to find out more about how music affects our brain!
