Mini Pixel and Large Pixel Chamber

When working with small (up to approximately 2cm2) or large (60x60cm^2) beams, we make use of different pixel chambers to ensure proper size, shape and uniformity are delivered to the target samples. The operator is able to monitor and tune the beam based off measurements that are displayed through these ion chambers.  Both of the chambers are useful when working with low flux beams that may not be visible to the beam imaging camera. The mini pixel chamber can also be used when operating with a small beam spot in order to minimize unnecessary material in the beam. The large pixel chamber is used when running with a 60 X 60cm2 beam where the digital beam camera and other ion chambers are too small to contain the entire beam.
