Tracking atomic reactions.

Part twenty seven creating an laser circuit etched asteroid satellite interstellar galaxies. Traditional imaging techniques can't be used to photograph BECs.
Because the extra energy added by the light in these cameras causes the particles to heat back up again, changing the gas back into a solid and destroying the BEC. What are BOSE-EINSTEIN CONDENSATES? When particles called bosons are cooled to temperatures close to absolute zero they turn into a dilute gas. This change of state is known as a Bose-Einstein condensate (BEC). Absolute zero is -273.15 Celsius (-459.67 Fahrenheit) is the coldest temperature possible. The boson particles change into this state because the drop in temperature reduces how much energy they have. Bose-Einstein condensates have zero viscosity and they behave like a single 'blob-like' mass. By studying these blobs, scientists can track atomic changes and processes. Traditional imaging techniques can't be used to photograph BECs because the extra energy added by the light in these cameras causes the particles to heat back up again, changing the gas back into a particle and destroying the BEC.

More recent scientific breakthroughs involved imaging the BECs using a type of laser imaging called off-resonant photons. This laser bounces its energy off the atoms, rather than into them, to avoid heating them too much. However, this process only works for a short period of time before too much energy is used and the BECs heat up again.
Michael Hush from the University of Nottingham, with researchers from Australia, have developed a computer program that simulates this off-resonant imaging, as well as the behaviour of the Bose -Einstein condensates to reveal exactly what happens during the process. They were then able to virtually filter the heating effect, and therefore the energy produced, into the magnetic coils used to keep the BECs cold to keep them cooler for longer and study the atomic processes for longer.

By studying BECs, scientists can track atomic processes. Samples of BECs were created in labs, using apparatus pictured, during the 1990s. Traditional imaging can't be used to photograph BECs because the energy added by the light causes the particles to heat up. They were then able to virtually filter the heating effect, and therefore the energy produced, into the magnetic coils used to keep the BECs cold. Instead of heating up the particles, this method meant the energy could be used to keep them cooler for longer, letting scientists study atomic processes for longer.
