  The radiation hardened beam instrumentations workshop was held on February
3rd and 4th, 2022 to identify the technological challenges on the beam
instrumentation for multi-Mega-Watt (MW) beam facilities. We invited a speaker
from a high energy neutrino beam facility (CERN, Fermilab and J-PARC), a
collider detector group (CERN and Fermilab), a neutron spallation source
facility (ESS, J-PARC and SNS), and a rare-isotope beam facility (FRIB).
Although, the operational beam parameter for each institution is unique due to
their different physics goals, we realize that there is a common issue on the
beam instrumentation. Therefore, it will be tackled by a collaborative R&D
effort among facilities. We summarize an output from the workshop in the paper,
and propose a possible R&D for the future radiation hardened beam
instrumentations with a global effort.
