mains ac xenon tube flasher circuit

The circuit was taken from one of the old elektor electronics magazine and it is indeed a very cute little circuit which may be used for creating high intensity lighting effects during festivals, parties and fun gatherings. Diodes D1 and D2 along with the capacitors C1 and C2 form a voltage doubler circuit which creates a voltage level twice the v

alue of the input voltage (across C1/C2). As the name suggests, its a tube filled with inert xenon gas. A metal ring is attached toward the anode side of the tube which becomes the gate trigger point of the device. Thisring isterminatedwith a wire so that it can be connected with s pulse source. When a high voltage is set across the anode/cathode pins of the tube and a pulse applied across the trigger gate wire and cathode, the tube gets charged up and allows the whole voltage across its Anode. cathode to pass through creating an intense arc lighting inside the tube due to thepassageof the high speed electrons through the xenon gas.
