	To provide electron bunches with exceptionally high brightness, RF gun cavity should operate with the extreme electric and magnetic fields. The RF probe is required for the mostly reliable and precise measurements of the RF field phase and amplitude directly from the cavity. The implementation of an RF probe in the cavity design generates a set of coupled problems, which is analyzed and compared for different operating frequencies and different RF pulse length. Both general dependencies and particularities are considered. Some recommendations for practical choice of the RF probe are presented.

A.G. Golovkina
St. Petersburg State University, St. Petersburg, Russia

The mathematical model of multi-point kinetics is proposed in the paper. The transients in subcritical reactor driven by proton linac taking into account the fuel and coolant temperature feedbacks are analyzed using this model. In contrast to the widely used point kinetics model, the proposed model makes it possible to more accurately take into account the heterogeneity of the material composition in the core. That is the one of the main features of transmutation systems with accelerator-driver.
