PVX-4140高壓脈沖發(fā)生器±3500V（粒子束靜電調制）
The PVX-4140 pulse generator is a direct-coupled, air-cooled solid-state half-bridge (totem pole) design, offering equally fast pulse rise and fall times, low power dissipation, and virtually no over-shoot, under-shoot or ringing. It has over-current detection and shut-down circuitry to protect the pulse generator from potential damage due to arcs and shorts in the load or interconnect cable. 該PVX-4140脈沖發(fā)生器是一個直接偶合式，風冷固態(tài)半橋式（圖騰柱）的設計，提供同樣快速脈沖上升和下降時間，功耗低，而且?guī)缀鯖]有過沖，下沖或者振鈴。在負載或者鏈接電纜，由于電弧和不足，它具有過流檢測和關閉電路來保護脈沖發(fā)生器受到潛在的損害。 All control and protection logic circuitry, support power, energy storage and output network are incorporated into the PVX-4140. It can be connected directly to the load, and does not require series or shunt resistors, impedance-matching networks between the pulser and the load, or additional energy storage (capacitor banks). All of this is taken care of within the PVX-4140. 所有的控制和保護邏輯電路，支持電力，能源儲存和輸出的網(wǎng)絡被納入PVX-4140。它可以直接連接到負載，并且不需要串聯(lián)或并聯(lián)的電阻，脈沖發(fā)生器和負載，或附加的能量儲存（電容器組）之間阻抗匹配網(wǎng)絡。所有這一切都被悉心照料在PVX-4140中。 Features 0 to ±3500V Pulse Output <25ns Rise And Fall Times >30KHz Pulse Repetition Frequency Protected Against Arcs, Shorts And Load Transients Voltage And Current Monitor Outputs 特點 0到±3500V脈沖輸出 <25ns上升和下降時間 >30KHz的脈沖重復頻率 防止弧，短路和負載瞬變 電壓和電流監(jiān)視器輸出 Applications The PVX-4140 is well suited for driving extraction grids and deflection plates for electrostatic modulation of particle beams in time-of-flight mass spectrometers and accelerators. Its robust and versatile design also makes it well suited for pulsing or gating power tube grids, Pockels cells and Q Switches, acoustic transducers, microchannel plates, photomultiplier tubes and image intensifiers. 應用 該PVX-4140是適合于驅動提取網(wǎng)絡和偏轉板上用于粒子束靜電調制在飛行時間的質譜法和加速器。它的強大和靈活的設計也使得它非常適合用于脈沖或門控功率管電網(wǎng)，普克爾盒和Q開關，聲換能器，微通道板，光電倍增管和圖像增強。
