  Silicon photomultipliers (SiPMs) are a good alternative to photomultiplier
tubes (PMTs) because their gain and quantum efficiency are comparable to PMTs.
However, the largest single-chip SiPM is still less than 1~cm$^2$. In order to
use SiPMs with scintillators that have reasonable sensitivity, it is necessary
to use multiple SiPMs. In this work, scintillation detectors are constructed
and tested with a custom 2x2 SiPM array. The layout of the SiPMs and the
geometry of the scintillator were determined by performing Geant4 simulations.
Cubic NaI, CsI, and CLYC with 18~mm sides have been tested. The output of the
scintillation detectors are stabilized over the temperature range between --20
and 50~$^{\circ}$C by matching the gain of the SiPMs in the array. The energy
resolution for these detectors has been measured as a function of temperature.
Furthermore, neutron detection for the CLYC detector was studied in the same
temperature range. Using pulse-shape discrimination, neutrons can be cleanly
identified without contribution from $\gamma$-photons. As a result, these
detectors are suitable for deploying in spectroscopic personal radiation
detectors (SPRD).
