@Mališa Vučinić Introducing @Sara Faour, new PhD student working on SCuM
- Get SCuM working over a wide range of temperatures then introduce security aspects
- @Kristofer PISTER suggests testing over a huge temperature range to demonstrate successful operation outside of usual crystal temperature ranges
