Variation of Control Characteristics of Power Thyratron Tubes With
Variation of control characteristics of power thyratron tubes with frequency by H W Snyder A THESIS Submitted to the Graduate committee In partial fulfillment of the requirements for the degree of Master of Science in Electrical Engineering Montana State University © Copyright by H W Snyder (1949) Abstract: A study was made of the variation in the control characteristics of three electrode thyratron tubes operation at frequencies up to 1080 cycles per second. Tests were made on thyratron tubes in half-wave rectification with magnitude d-c grid voltage control. The existence of two control characteristics, a starting control characteristic and an extinguishing control characteristic, at higher-than-power frequencies was confirmed. The starting control characteristic was determined to be dependent uoon frequency of spoiled anode voltage, lnterolectrode capacitance, and tube "dark" currents which are determined by geometry of electrode structures. Extinguishing control characteristic was found to be a tube deionization phenomenon. VA IATION 07 CO-T OL GHA . 4CT2BI3 TIC5 OF 'OmLA THYKATAOw TJDGJ AlTH FRGQJZNCY by H. - .

One of the most significant advancements presented for discharge-pumped gas lasers. The IGBTs are connected in switching is the invention of the IGBT by B. J.

Gas Discharge Tubes If You've Ever Witnessed a Lightning Storm, You've Seen Electrical Hysteresis in Action (And Probably Didn't Realize What You Were Seeing)
Gas discharge tubes If you've ever witnessed a lightning storm, you've seen electrical hysteresis in action (and probably didn't realize what you were seeing). The action of strong wind and rain accumulates tremendous static electric charges between cloud and earth, and between clouds as well. Electric charge imbalances manifest themselves as high voltages, and when the electrical resistance of air can no longer hold these high voltages at bay, huge surges of current travel between opposing poles of electrical charge which we call "lightning." The buildup of high voltages by wind and rain is a fairly continuous process, the rate of charge accumulation increasing under the proper atmospheric conditions. However, lightning bolts are anything but continuous: they exist as relatively brief surges rather than continuous discharges. Why is this? Why don't we see soft, glowing lightning arcs instead of violently brief lightning bolts? The answer lies in the nonlinear (and hysteric) resistance of air. Under ordinary conditions, air has an extremely high amount of resistance. It is so high, in fact, that we typically treat its resistance as infinite and electrical conduction through the air as negligible. The presence of water and dust in air lowers its resistance some, but it is still an insulator for most practical purposes. When enough high voltage is applied across a distance of air, though, its electrical properties change: electrons become "stripped" from their normal positions around their respective atoms and are liberated to constitute a current. In this state, air is considered to be ionized and is called a plasmarather than a gas.
