Zusammenfassung:Systems and methods used to deliver a processing gas having a desired diborane concentration to a processing volume of a processing chamber are provided herein. In one embodiment a system includes a borane concentration sensor. The borane concentration sensor includes a body and a plurality of windows. Here, individual ones of the plurality of windows are disposed at opposite ends of the body and the body and the plurality of windows collectively define a cell volume. The borane concentration sensor further includes a radiation source disposed outside of the cell volume proximate to a first window of the plurality of windows, and a radiation detector disposed outside the cell volume proximate to a second window of the plurality of windows.
