Status of the Upgrades for the CMS Hadron Calorimeter (to be merged with 86)

The CMS collaboration is planning a set of improvements to the detector's hadron calorimeters in the coming years. These changes will include the replacement of the HPD photodetectors with silicon photomultipliers, the introduction of increased depth segmentation to the calorimeter, and the inclusion of TDC capabilities to the detector's ADCs. The status of the research and development for these upgrades will be discussed, along with the results from the testing of the upgraded microTCA readout electronics which is being evaluated with current LHC data taking.
