Description
We propose a new radio frequency timer of keV energy electrons. By converting a time distribution of incident electrons to a hit position distribution on a circle, ellipse or spiral, by means of the radio frequency fields laying in the range 500-1000 MHz, this device achieves extremely precise timing. Streak Cameras, based on similar principles, routinely operate in the ps and sub-ps time domain, but have substantial dead time associated with the readout system. Here, we present a new type of RF timing technique, where the position sensor, consisting of microchannel plates and a delay-line anode, position information produces in the form of a ∼ns duration pulses and readout can be realized by using regular electronics. Measurements made with sub-ps duration laser pulses, synchronized to the radio frequency power, produced a timing resolution of ∼10 ps. This ultra-high precision technique has potential applications in a large variety of scientific devices.
