  High performance calorimetry conducted at future hadron colliders, such as
the FCC-hh, poses a significant challenge for applying current detector
technologies due to unprecedented beam luminosities and radiation fields.
Solutions include developing scintillators that are capable of separating
events at the sub-fifty picosecond level while also maintaining performance
after extreme and constant neutron and ionizing radiation exposure. The RADiCAL
is an approach that incorporates radiation tolerant materials in a sampling
'shashlik' style calorimeter configuration, using quartz capillaries filled
with organic liquid or polymer-based wavelength shifters embedded in layers of
tungsten plates and LYSO crystals. This novel design intends to address the
Priority Research Directions (PRD) for calorimetry listed in the DOE Basic
Research Needs (BRN) workshop for HEP Instrumentation. Here we report
preliminary results from an experimental run at the Fermilab Test Beam Facility
in June 2022. These tests demonstrate that the RADiCAL concept is capable of <
50 ps timing resolution.
