X-ray camera makes A-grade particle detector
In the particle identification business, two pieces of information are vital: energy and spatial location. By measuring its energy you can work out the mass of your mystery particle. From its spatial location on the surface of a detector, you can work out where the particle came from and therefore how big the event was that produced the particle in the first place. For the range of energies close to one million electron volts (1 MeV) a popular energy range to probe, with uses in a variety of fields from cancer treatment research to astrochemistry there are currently two leading methods of detecting particles. But both are limited in the types of molecules they can detect, and both sacrifice one type of information spatial location or energy measurements for the other.
