Xenon strobe electronic circuit project

A very simple strobe can be made using electronic scheme from this figure. Strobe is connected directly to the outlet, so measurements and experiments are very dangerous .
Potentiometer P1 used should have a plastic spindle and must be mounted so that no metal part of it, can not be touched.
Strobe is made with a gas discharge bulb, which is U-shaped and filled with xenon.
Diodes D1 and D2 together with capacitors C1 and C2 form a dual voltage mains voltage raises to about 600 V, voltage is applied between the anode and cathode tube.
To ignite the lamp is required 5 ... 10 kV at the control electrode. Lamp ignition occurs after the gas insulation barrier penetrations and is accompanied by a large increase in current through the tube. Relatively high potential for grid order is obtained from the ignition transformer TR1. To produce a high potential in the secondary winding, the primary current to be interrupted suddenly, it made the thiristor Th1.
Capacitor C3 is charged from capacitor C2 (charged to 300 V) by TR1 transformer primary, which has a low resistance. Once the threshold of the diodes D3 and D4 penetration is reached, triac Th1 enter in conduction state. At this point, the capacitor C3 is discharged quickly through the primary winding of TR1, which will induce a voltage in the secondary winding huge determining xenon tube ignition.
Adjust P1 determine load capacitor C3 and therefore the ignition frequency of the tube.
Resistance R1 is coupled to the neutral network and is used as a current limiter.
Gas discharge tube can be of type 60 W / s and can be purchased in stores (as well as ignition transformer).
