Abstract :

For the preparation of the CMS Phase I upgrades, which consisted of the replacement of the photomultiplier tubes, we tested 1800 Hamamatsu R7600U-200-M4 photomultiplier tubes at the University of Iowa Photodetector Test Laboratory. Among the tests performed, measurements of gain, response uniformity and linearity can be listed. The new photomultiplier tubes will provide better light detection performance, a significantly reduced background and unique handles to recover the signal in the presence of background. This report will provide the details of the photomultiplier tube measurements; describe the calorimetry upgrade and the nature of the essential upgrade elements with supporting test results.
