PVX-4140高壓脈沖發(fā)生器±3500V（粒子束靜電調(diào)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(gè)直接偶合式，風(fēng)冷固態(tài)半橋式（圖騰柱）的設(shè)計(jì)，提供同樣快速脈沖上升和下降時(shí)間，功耗低，而且?guī)缀鯖]有過沖，下沖或者振鈴。在負(fù)載或者鏈接電纜，由于電弧和不足，它具有過流檢測(cè)和關(guān)閉電路來保護(hù)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(hù)邏輯電路，支持電力，能源儲(chǔ)存和輸出的網(wǎng)絡(luò)被納入PVX-4140。它可以直接連接到負(fù)載，并且不需要串聯(lián)或并聯(lián)的電阻，脈沖發(fā)生器和負(fù)載，或附加的能量儲(chǔ)存（電容器組）之間阻抗匹配網(wǎng)絡(luò)。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(diǎn) 0到±3500V脈沖輸出 <25ns上升和下降時(shí)間 >30KHz的脈沖重復(fù)頻率 防止弧，短路和負(fù)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(yīng)用 該P(yáng)VX-4140是適合于驅(qū)動(dòng)提取網(wǎng)絡(luò)和偏轉(zhuǎn)板上用于粒子束靜電調(diào)制在飛行時(shí)間的質(zhì)譜法和加速器。它的強(qiáng)大和靈活的設(shè)計(jì)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(guān)，聲換能器，微通道板，光電倍增管和圖像增強(qiáng)。
