Even if you have n’t seen any James Bond films , you ’re likely cognizant that thespace optical maser battledepicted in Moonraker rank among the dazed setting in the franchise ’s account . But there ’s a raw laser gun in township that ’s actually sound and opening up for business . It is not a weapon .
The European X - ray Free Electron Laser ( XFEL ) will begin control in September , and it will shoot 27,000 optical maser pulses per minute , 200 times more per 2nd than the next highest - performing gun in California . scientist do n’t often expend laser guns to snap astronauts , and only sometimes apply them to channelize PowerPoints . Instead , cerebrate of the European XFEL as an incredibly gamy - speed and elaborated motion-picture show camera .
“ That sucks , and is not what laser do in movies , ” is a thought you might have . But bear with me , the European XFEL is really kind of cool .
The 1.5 billion - euro optical maser supersede its predecessor , FLASH , in Germany . According to theexperiment ’s site , the organization hold in 768 cavities on a one - nautical mile foresightful tobacco pipe with alternate electromagnetic line of business , send the electrons back and forth in a wobble . Changing an negatron ’s direction do it to pip light forrader , but then that light ( which moves a little moment faster than the high - muscularity electrons ) , also influences how the electron move and go on to beam , in turn creating the x - ray of light pulses . The experimentation floor the electrons and stay fresh the ex - rays .
A lot of high - zip , bantam x - beam heart rate means the gadget can be used to take detailed pictures of cells or particle like protein down to their atoms . They can also get really fast phenomena , like chemical bonds forming , according to theEuropean XFEL internet site . The radiation can also be used to study private atoms or molecules under extreme conditions . You may have visualise some of the work done usingsynchrotron radiation sickness — that ’s the kind of stuff scientist might need to do with the European XFEL . This can help researchers empathize the most canonic physics , or help them develop new drugs based on the best potential knowledge of cells and their function .
There are other ten - shaft of light lasers in enjoyment , and they ’re in high requirement by scientist , but they do n’t touch nearly the public presentation of the newest one ; one in California pulses 120 times per second , while another in Japan break away at 60 pulsation per second , agree toa jam release on Phys.org . But other innovative optical maser guns came online recently or will open shortly , report Nature , including one in Switzerland and another in South Korea .
Germany has been celebrating — laser are shining over the nearby urban center of Hamburg to hail theexperiment ’s comer .
But as right as XFEL is , it wo n’t prevail supreme for long , writes Nature . The SLAC National Accelerator Laboratory will open up a readiness that can pulse a million time per s in the 2020s .
