Electrostatic and ferrite core monitors in the TARN

Electrostatic monitors and a ferrite core one are installed in the TARN. As these monitors do not disturb a beam in detection, they are efficient for the operation of the TARN, for instance, for the adjustment of the injection system. One of the monitors works in the loop of phase locking system for the RF stacking. To reject the noise from the RF system, a harmonic of a higher order in the beam signal is extracted through a resonator. In this report, the construction of the monitors and the characteristics of the TARN measured by them are described. (author)
