Made in ex-USSR in 80' year.
History
One of the few cavity flash lamps. Its most well-known application is the pumping of a ruby active element in the head of a pulsed holographic setup. The laser head itself, due to such a strange design of the lamp, also looked unusual and, for the most part, collective farm.
However, as practice has shown, the efficiency of these lamps as pumping lamps left much to be desired - in fact, only that part of the light flux that irradiates the active element inside the cavity is used. What leaves the outside of the lamp, although it is reflected, still does not get inside. And the reliability of such lamps left much to be desired.
Another unpleasant effect of this design is the low inductance of the discharge channel, which led to high pulsed currents and required the introduction of a pull-down choke. However, often its role was played by a transformer for sequential ignition of the lamp. But this did not prevent the lamps from sometimes exploding, crippling the active element and head reflectors.
Later, a modification of this lamp was released under the name IFPP2-7000. The changes affected mainly the shape of the electrodes, the methods of their soldering, and the presence of seals on the terminals made of silicon-organic material.
The only known Soviet-made cavity lamp, the IFPP-7000, was used to pump the UIG-1 laser machine.
Parameters:
The operating voltage on the storage capacitor is 2600 V (maximum allowable 2340 V from the bottom and 2860 V from the top)
The capacity of the storage capacitor is 1800 uF.
The duration of the light pulse is 1 ms.
The smallest interval between flashes is 30 seconds.
Size: 250x180 mm. Diameter of tube 30 mm.
Accordingly, the energy at which the lamp is operated should not exceed about 6 kJ.
First too photos is from internet, that I liked very much, other is actual mine on this item that you will receive!
