Much of the development work on the photomultiplier tube was performed by RCA in facilities in the United States and the former Soviet Union in the latter half of the 20th century. The superior sensitivity (high current amplification and high S/N ratio) of photomultiplier tubes is due to the use of a low-noise electron multiplier which amplifies electrons by a cascade sec- ondary electron emission process. (A) For the 3‐Laser FACSAria, the Cytometer Settings results (fixed PMTs) showed very good stability, with day‐to‐day variation <5% in both the V450 channel (near UV laser, 375 nm), PerCP and PC7 channels (blue laser, 488 nm), and the APC channel (red laser, 633 nm). Today, the photomultiplier tube remains unequalled in light detection in all but a few specialized areas. Photomultiplier tubes (PMTs) has been saved to your wishlist successfully. On these days concurrent increases in APC channel PMT voltage was seen (right graph). Photomultiplier tubes (PMTs), also known as photomultipliers, are remarkable devices. The data presented in the present study was primarily acquired on an LSRFortessa instrument, and 8‐peak Rainbow beads MFI stability on the Fortessa is shown in Figure 5.
