Abstract
To conduct experiments to determine the amplitude of the electric field and the transformation ratio in the wake field accelerator based on dielectric structures excited by electron bunches of the Almaz-2 electron accelerator, a probe was developed and manufactured. The probe consists of a ¼ wavelength antenna (27 mm) and a detection circuit based on a 2A201A microwave diode. To calibrate the probe, a measuring stand was assembled, consisting of a microwave generator and a horn emitter. A SPEKTRAN spectrum analyzer (Germany) was used as a microwave power meter, and a digital oscilloscope was used as a meter of the detected signal from the probe. The results of measurements made on the stand show that at a microwave radiation power of 26 mW/m2 and an electric microwave field strength of 2.6 V/m at the measurement point, the output signal from the probe is 1 mV.
