    Abstract: Systems, devices, and methods for converting a raw neutron beam to a specified deliverable format having a targeted energy range, size, and direction are described. Embodiments of a neutron beam converter can include numerous regions based on location, function, dimension, and/or constituent material. The regions can include a central region, an intermediate region, a peripheral region, and a frontal region. Materials are also described.

    Abstract: A method for monitoring and controlling neutron beams includes performing a calibration process for a monitoring dosimeter at a first set of conditions for directing a neutron beam towards an object location, the neutron beam being emitted from a neutron-generating target in response to an incident charged particle beam, the process comprising: obtaining data indicating a first neutron flux measured by the monitoring dosimeter between the monitoring dosimeter and the object location, the monitoring dosimeter offset from the axis by a distance equal to or greater than the beam radius; obtaining data indicating a second neutron flux measured by a reference dosimeter between the target and the object location; storing calibration data including a correlation between the first neutron flux and the second neutron flux; and based on the calibration data, using the monitoring dosimeter to monitor neutron flux incident on a patient during boron neutron capture therapy treatment.
