Featured Inquiry 1:
I am interested in finding out more information about your triggered spark gaps for a project I am working on. My requirements are a standoff of up to 40 kV, a peak current of around 10 kA, a pulse energy of 100 J, and a pulse rep rate of 20 Hz. I also need a very long life gap. At least 10^8 firings. Can you provide a product to meet these requirements?

Featured inquiry 2:
We are making an Ignitor for Igniting a 250W Xenon ARC. Lamp and we need a
suitable Ignitor which can generate voltage of up to 40KV for ignition of Xenon
Please see the picture of the reference Spark gap as an attachment. We require a
device which has a similar working to this spark gap shown in the picture.
The coil or the transformer we have already made and it works well with the
spark gap shown in picture.
Please suggest suitable model which falls under your range of production so that we may start trials and freeze ASAP.

Thyratrons are used in such devices as radars with
different power levels, high-power pulsed technical, electrophysical,
medical devices and lasers. Sophisticated design and high quality
ceramic-metal envelope determines long lifetime and very accurate and
reliable operation of hydrogen thyratrons under wide range of environmental
- pulsed lasers power supplies
- medical apparatus
- electrophysical instrumentation
Triggered Three-Electrode Spark Gap Switches are ceramic-metal sealed off gas discharge trigatron-type devices with a co-axial trigger electrode. These Gas Discharge Tubes contain no mercury and, due to an advanced design, feature high reliability and a long lifetime being operating under wide range of environmental conditions.

Del Mar Photonics supply trigger transformers for triggered spark gaps and other applications. Contact us to today to discuss your application or requesta quote.
Trigger Transformers are used to provide a fast high voltage pulse up to 30kV/Ás and more. This high voltage pulse is applied to the trigger electrode to initiate switching action in the three-electrode spark gaps. Either positive or negative pulses can be obtained from all of the transformers.
