We describe a novel particle telescope, the Advanced enerGetic Ion eLectron tElescope (AGILE), which utilizes

full pulse shape discrimination to identify solar energetic particles (SEP), and characterizes their spectra from

about 2 to 200 MeV/nuc for most species from H to Fe. AGILE is a compact, low mass, and low-power particle

telescope suitable for CubeSat platforms that enable multi-point measurements in interplanetary space. AGILE will

employ high heritage solid state detectors, a state-of-art high-speed sampling ASIC, as well as novel algorithms to

characterize SEP to advance the

understanding of charged particle energization, loss, and transport throughout the heliosphere.

AGILE will resolve ion isotopes (e.g. $^3$He vs. $^4$He) with high robustness and reliability.

Currently, a prototype of the instrument is being built and will be part of

science payload on the GenSat-1 CubeSat. GenSat-1 is expected be launched early 2022 into a

high inclination low earth orbit, with AGILE collecting data over the polar regions, i.e., the open field line

regions accessed by SEP.
