There is a need for a new and innovative photon detector that can replace the photomultiplier tube (PMT) in particle physics experiments. This photon detector has to fix the shortcommings of the PMT, yet retain the advantages that the PMT provided. If such a photon detector could be found, it would revolutionalize the way photons are detected in high energy physics and could influence the design and structure of particle accelerators themselvese.
The new photon detector has to fix the primary flaws of the PMT, namely its large size and its sensitivity to magnetic fields. The new Silicon Photomultiplier (SiPM) is a device that has the potential. Instead of using a series of dynodes to amplify the signal of the photon, it uses 2 highly charged electron plates.
