The phrase "are accelerated in a" is correct and usable in written English.
It can be used in contexts where you are discussing processes or phenomena that are being sped up or enhanced in a particular manner or environment.
Example: "The reactions are accelerated in a controlled environment to ensure optimal results."
Alternatives: "are hastened in a" or "are expedited in a".
This generates tight bunches of electrons that are accelerated in a 1-kilometer section of SLAC's linear accelerator.
Subsequently they are accelerated in a high-power superconducting radio-frequency (SRF) linac that has been constructed in my group.
An example is the coating formation process Cold Spray (CS), in which high Stokes number particles are accelerated in a supersonic nozzle and free jet.
There he made the first direct observation of synchrotron radiation -- the electromagnetic radiation given off when high-energy particles are accelerated in a strong magnetic field -- and its experimental verification in 1945.
The results support the viewpoint that electrons that generate the continuum gamma-ray and hard X-ray emissions in impulsive solar flares are accelerated in a turbulent reconnecting current sheet.
One explanation for this emission would be what is called synchrotron radiation, which arises when charged particles are accelerated in a magnetic field.
Working independently, they improved a technique known as mass spectrometry to identify proteins by how quickly they are accelerated in an electric field.
They are accelerated in an air eductor, and are impacted onto a target in the velocity range 15 – 30 ms−15
Dr. Fenn improved a technique known as mass spectrometry, which identifies molecules like proteins by how quickly they are accelerated in an electric field.
The process discussed in the article is ion implantation which is a material engineering process by which ions of a material are accelerated in an electrical field and impacted into a solid.
Ironically, this is precisely what has been accelerated in a desperate effort to raise scores on standardized tests, the heart of the reform efforts you champion.
