A new free electron laser is proposed. It is composed of two electron beams-the inner beam moves along a straight line while the outer one travets in a helical orbit. The operation mechanism of the new FEL is that the outer beam works as the cyclotron maser pump while the inner one serves as the lasing active medium.The advantage of this new FEL is tnat with the same beam energy it has the shorter wavelength than that of the FEL with the magnetie wiggler pump. This is because the outer beam is in essence a large-orbit...

This is because the outer beam is in essence a large-orbit ggrotron which is suitable for harmonic operation. The two beams might be produced by one electron gun so that no extra kind of eguipment is needed.Vlasov kinetic theory of the FEL with cyclotron maser pump is presented, linear growth rate obtained and two schemes of cyclotron maser pumps are proposed.

本文提出一种新的自由电子激光器方案,由内外两束电子构成,内电子束作直线运动,外电子束产生回旋脉塞不稳定性,其辐射的回旋波反射后充当泵波,与作为激光工作物质的内电子束相互作用,产生相干散射。这种新方案的优点是:在相同的电子束能量下,可以获得比常规自由电子激光短的波长。这是因为外束实际上是一种大轨道回旋管,适合工作于高次谐波 此外,它结构紧凑,产生泵波的外束可与内束共用一个高压电源和真空系统,甚至可由同一电子枪产生,不增加设备种类。 本文给出了回旋脉塞泵自由电子激光的动力学理论,求得了线性增益,并提出了两种回旋脉塞泵方案。

Aiming at the phenomena such as big noise from the equipment, unstable pressure,deposition inside the pump shell, serious corrosion of some parts and high emulsification of the fluid in the use of zinc-containing antiwear hydraulic fluid, the relation between the performance of the fluid and its chemical composition and structure was studied. The rig test showed that the performance of the zinc-con-taining antiwear hydraulic fluid not only related to its zinc content, but also affected by calcium content.Adding...

The rig test showed that the performance of the zinc-con-taining antiwear hydraulic fluid not only related to its zinc content, but also affected by calcium content.Adding a proper amount of calcium-containing detergent can increase the hydrolytic and thermal stabilities of the fluid.

According to the design discharge capacity andpressure of the flooding well, the calculatingmethod of the parameters and construction designof water flood pump set is given out, it is provedfrom the practical site utilization that using theelectric submersible pump as water flooding pumpcan get water from scattered water source,and thepump can operate outdoors,thus costing less basicmoney. Water flooding electric pump operatesmoothly,less troubles and maintainace- Althoughit consumes more electrcity than the piston pump,the latter needs much more basic investment. Syn-thetically comparing, the benefits of the sub-mersible water flooding pump is better than thepiston pump.
